[security-sig] Cancelling this month's meeting
by Jeremy Stanley 02 Nov '22

02 Nov '22

I'm on vacation this week and don't expect to be around a computer tomorrow in order to chair the meeting, so am cancelling it for November. If anyone had topics they wanted to bring up, please just raise them here on the ML or in the #openstack-security channel on OFTC and I'll try to follow up there as appropriate. Additionally, we discussed at the PTG that the standing meeting time is inconvenient for multiple participants, so I'll be following up with a poll to work out a more consensual schedule. Thanks! -- Jeremy Stanley

[Kolla-ansible][Xena] How to update an Openstack deployment with new containers?
by wodel youchi 01 Nov '22

01 Nov '22

Hi, The documentation of kolla-ansible Xena does not talk about updating an existing Xena deployment with new containers. Could you please help with this? I found some lines about that in Yoga version, saying that, to update an existing deployment you have to : 1 - Update kolla-ansible it self : $ source xenavenv (xenavenv) $ pip install --upgrade git+ https://opendev.org/openstack/kolla-ansible@stable/xena 2 - Update the container Images with Docker pull 3 - Update my local registry if I am using one, and in my case I am, so I deleted the registry images then I recreated them. 4 - Then finally deploy again (xenavenv) $ kolla-ansible -i multinode deploy Is this the right procedure? because I followed the same procedure and I think it didn't change anything. For example I am taking nova-libvirt container as and example, in my local registry I have this : [root@rcdndeployer2 ~]# docker images | grep nova-libvirt 192.168.2.34:4000/openstack.kolla/centos-source-nova-libvirt xena 5be83d680102 31 hours ago 2. 34GB quay.io/openstack.kolla/centos-source-nova-libvirt xena *5be83d680102* *31 hours ago * 2. 34GB [root@rcdndeployer2 ~]# docker inspect -f '{{ .Created }}' *5be83d680102 * *2022-10-25*T02:33:13.172550584Z But in my compute nodes I have this : root@computehci24 ~]# docker ps | grep nova-lib b56a12bfd482 192.168.2.34:4000/openstack.kolla/centos-source-nova-libvirt:xena "dumb-init --single-…" *5 months ag**o Up Up 5 months (healthy) nova_libvirt* Regards.

Discontinuing Winstackers
by Lucian Petrut 01 Nov '22

01 Nov '22

Running Openstack on Windows has been driven by Cloudbase Solutions ever since Folsom (2012). Here are the most noteworthy contributions: * nova hyper-v driver - in-tree plus out-of-tree compute-hyperv driver * os-win - common Windows library for Openstack * neutron hyperv ml2 plugin and agent * ovs on Windows and neutron ovs agent support * cinder drivers - SMB and Windows iSCSI * os-brick Windows connectors - iSCSI, FC, SMB, RBD * ceilometer Windows poller * manila Windows driver * glance Windows support * freerdp gateway * last but not least, CI test systems for (most of) the above Due to a shift in business focus and the increased operational costs of maintaining the CI systems, we are no longer in a position to proactively support Openstack on Windows. However, we will continue to support Cloudbase-init (cloud-init equivalent for Windows) as well as the Openstack Windows imaging tools. If there are any interested parties that would like to step up as Winstacker maintainers, please let us know and we will provide any required assistance. Regards, Lucian Petrut Cloudbase Solutions Winstackers PTL

[OSSN-0091] BMC emulators developed in OpenStack community do not preserve passwords on VMs
by Jay Faulkner 31 Oct '22

31 Oct '22

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 ## Summary ## When deploying VirtualBMC or Sushy-Tools in an unsupported, production-like configuration, it can remove secret data, including VNC passwords, from a libvirt domain permanently. Operators impacted by this vulnerability must reconfigure any secret data, including VNC passwords, for the libvirt domain. These virtual machine emulators are tools to help emulate a physical machine's Baseboard Management Controller (BMC) to aid in development and testing of software that would otherwise require physical machines to perform integration testing activities. They are not intended or supported for production or long-term use of any kind. ## Affected Services / Software ## * Sushy-Tools, <=0.21.0 * VirtualBMC, <=2.2.2 There is no impact to any OpenStack software or services intended for production use. ## Patches ## * VirtualBMC: https://review.opendev.org/c/openstack/virtualbmc/+/862620 * Sushy-Tools: https://review.opendev.org/c/openstack/sushy-tools/+/862625 ## Discussion ## To perform some advanced operations on Libvirt virtual machines, the underlying XML document describing the virtual machine's domain must be extracted, modified, and then updated. These specific actions are for aspects such as "setting a boot device" (VirtualBMC, Sushy-Tools), Setting a boot mode (Sushy-Tools), and setting a virtual media device (Sushy-Tools). This issue is triggered when a VM has any kind of "secure" information defined in the XML domain definition. If an operator deploys VirtualBMC or Sushy-Tools to manage one of these libvirt VMs, the first time any action is performed that requires rewriting of the XML domain definition, all secure information -- including a VNC console password, if set -- is lost and removed from the domain definition, leaving the libvirt VM's exposed to a malicious console user. ## Recommended Actions ## Operators who may have been impacted by this vulnerability should immediately remove use of VirtualBMC and/or Sushy-Tools from their production environment. Then, validate and if necessary, reconfigure passwords for VNC access or any other impacted secrets. ## Notes ## The OpenStack team will ensure documentation is updated to clearly state these software packages are intended for development/CI use only, and are not safe to run in production. ## Credits ## Julia Kreger from Red Hat ## References ## Author: Jay Faulkner, G-Research Open Source Software This OSSN: https://wiki.openstack.org/wiki/OSSN/OSSN-0090 Original Storyboard bug: https://storyboard.openstack.org/#!/story/2010382 Mailing List : [Security] tag on openstack-discuss(a)lists.openstack.org OpenStack Security Project : https://launchpad.net/~openstack-ossg CVE: CVE-2022-44020 -----BEGIN PGP SIGNATURE----- Version: FlowCrypt Email Encryption 8.3.8 Comment: Seamlessly send and receive encrypted email wsFzBAEBCgAGBQJjYDhhACEJEGt12Tm0JMbUFiEEvF1YmsGLSYuWqE+ta3XZ ObQkxtSCUw/9FEeakvlf06BWrk5Lc3TGwUKV0WiLaE4M0xjljkzg/3/580/E nhOTl/raPszlzgkGdrQTaH3Sj4AwUTdPHqqxjyK/Xb1DIm+CfS3bdbP0aLHG Y3Su4Z74unMaKbnbyDYhM1qMIzPyBruLpqiyYJGhSuzU/fu1O/LCWfSicvKK YDmAHJ9TjXuTMdWrLrkMknvJaLe0aJrNW5iqDnIh6YrUC2Pioi5h+OFKwDpn Ea+YnlAxKR7OQGRGcY3AwP1Jq87pdHZagcVThc/wnCATKT/FtaIogDkUnoMn qI+6MNjV3R4kyQCbyo35KeIDWm+541XsK0GoR5hcvR1AkwciSPBAkt3VHxpa p0g9hVcNTv+tWwN8LrdLRPMDuqKA51eNUvQCV8W+H42wS0uoaMPXglbZIuwv AmEoK8UC8Gii8cPoIkiZGSSOo4i+tlE/q+L/Mgs1opyt1Klcxs/Lm1PNylET XqLw70qKrfqWabZpKUxMS3F9JwyCkgnD5+t2x/qsqg5Hq+kUZqP8be3Oc7K7 He/gIneWDMpH1+J9Tm5ofyxtJCA+V96+cXoXYk8SncVf/O5djgd48UkQo1iJ NZlKxJsaKH5+JyPuXkR6hyqDrIkmbJRh4aU9nJBQyFho0fXuQVlC2iUOGa0F BgUFs5J6oQtglAAuyUoNuhuBJBwdW09NxQ4= =6yXE -----END PGP SIGNATURE-----

[oslo][tooz][openstack-ansible] Discussion about coordination (tooz), too many backend options, their state and deployment implications
by Christian Rohmann 31 Oct '22

31 Oct '22

Hallo openstack-discuss, apologies for this being quite a long message - I tried my best to collect my thoughts on the matter. 1) The role of deployment tooling in fulfilling the requirement for a coordination backend I honestly write this, triggered by openstack-ansible plans to add coordination via the Zookeeper backend (https://lists.openstack.org/pipermail/openstack-discuss/2022-October/031013…) On 27/10/2022 13:10, Dmitriy Rabotyagov wrote: > * Add Zookepeer cluster deployment as coordination service. > Coordination is required if you want to have active/active > cinder-volume setup and also actively used by other projects, like > Octavia or Designate. Zookeeper will be deployed in a separate set of > containers for LXC path First of all I believe it's essential for any OpenStack deployment tooling to handle the deployment of a coordination backend as many OS projects just rely in their design and code to have it in place. But I am convinced though there too many options, that some stronger guidance should be given to people designing and then deploying OS for their platform. This guidance certainly can be in the form of a comparison table - but when it comes to using deployment tooling like openstack-ansible, the provided "default" component or options for something might just be worth more than written text explaining all of the possible approaches. This hold especially true to me as you can get quite far with no coordination configured which then results in frustration and invalid bugs being raised. And it's not just openstack-ansible thinking about coordination deployment / configurations. To just point to a few: * Kolla-Ansible: https://lists.openstack.org/pipermail/openstack-discuss/2020-November/01883… * Charms: https://bugs.launchpad.net/charm-designate/+bug/1759597 * Puppet: https://review.opendev.org/c/openstack/puppet-oslo/+/791628/ * ... 2) Choosing the "right" backend driver I've recently been looking into the question what would be the "best" tooz driver to cover all coordination use cases the various OS projects require. Yes, the dependencies and use of coordination within the OS projects (cinder, designate, gnocchi, ...) are very different. I don't want to sound unfair, but most don't communicate which of the Tooz services they actually require. In any case, I might just like something to cover all possible requirements to "set it (up) and forget it, no matter what OS projects run on the platform. Apart from basic compatibility, there are qualities I would expect (in no particular order) from a coordination backend: * no "best-effort" coordination, but allowing for actual reliance on it (CP if talking CAP) * HA - this needs to be working just as reliably as my database as otherwise the cloud cannot function * efficient in getting the job done (e.g. support for events / watches to reduce latency) * lightweight (deployment), no additional components, readily packaged * very little maintenance operations * easy monitoring I started by reading into the tooz drivers (https://docs.openstack.org/tooz/latest/user/drivers.html) of which there are more than enough to require some research. Here are my rough thoughts: a) I ruled out the IPC, file or RDBMs (mysql, postgresql) backend options as they all have strong side-notes (issues when doing replication or no HA at all). Additionally they usually are not partition tolerant or support watches. b) Redis seems quite capable, but there are many side notes about HA and this also requires setting up and maintaining sentinel. c) Memcached supports all three services (locks, groups, leader-election) tooz provides and is usually already part of an OpenStack infrastructure. So looked appealing. But it's non-replicating architecture and lack of any strong consistency guarantees make it less of a good "standard". I was even wondering how tooz would try it's best to work with multiple memcached nodes (https://bugs.launchpad.net/python-tooz/+bug/1970659) d) Then there only is Zookeeper left, which also ticks all the (feature-)boxes (https://docs.openstack.org/tooz/latest/user/compatibility.html) and is quite a proven tool for coordination also outside of the OpenStack ecosystem. On the downside it's not really that well known and common (anymore) outside the "data processing" context (see https://cwiki.apache.org/confluence/display/ZOOKEEPER/PoweredBy) Being a Java application it requires a JVM and its dependencies and is quite memory heavy to store just a few megabytes of config data. Looking at more and more people putting their OS control plane into something like Kubernetes it also seems even less suitable to be "moved around" a lot. Another issue might be the lack of a recent and non-EoL version packaged in Ubuntu - see https://bugs.launchpad.net/ubuntu/+source/zookeeper/+bug/1854331. Maybe (!) this could be an indication of how commonly it is used outside of e.g. Support from TLS was only added in 3.5.5 (https://zookeeper.apache.org/doc/r3.5.5/zookeeperAdmin.html#Quorum+TLS) e) Consul - While also well known and loved, it has, like Zookeeper, quite a big footprint and is way more than just a CP-focused database. It's more of an application with man use cases. f) A last "strong" candidate is etcd. It did not surprise me to see it on the list of possible drivers and certainly is a tool known to many from running e.g. Kubernetes. It's actually already part of openstack-ansible deployment code as a role (https://github.com/openstack/openstack-ansible/commit/2f240dd485b123763442a…) as it is required when using Calico as SDN. While etcd is also something one must know how to monitor and operate, I allow me to say it might just be more common to find this operational knowledge. Also etcd has a smaller footprint than Zookeeper and it beeing "just a Golang binary" comes with (no) less dependencies. But I noticed that it does not even support "grouping", according to the feature matrix. But apparently this is just a documentation delay, seehttps://bugs.launchpad.net/python-tooz/+bug/1995125. What's left to implement would be leader-election, but there seems to be no technical reason why this cannot be done. this by no means is a comparison with a clear winner. I just want to stress how confusing having lots of options with no real guidance are. The requirement to chose and deploy coordination might not be a focus when looking into designing an OS cloud. 3) Stronger guidance / "common default", setup via OS deployment tooling and also used for DevStack and tested via CI To summarize, there are just too many options and implications in the compatibility list to quickly chose the "right" one for one's own deployment. While large-scale deployments might likely not mind for coordination to have a bigger footprint and requiring more attention in general. But for smaller and even mid-size deployments, it's just convenient to offload the configuration of coordination and the selection the backend driver to the deployment tooling. Making it way too easy for such installations to not use coordination and running into issues or every other installation using a different backend creates a very fragmented landscape. Add different operating system distributions and versions, different deployment tooling, different set and versions of OS projects used, there will be so many combinations. This will likely just cause OS projects to receive more and non-reproducible bugs. Also not having (a somewhat common) coordination (backend) used within CI and DevStack does not expose the relevant code paths to enough testing. I'd like to make the analogy to having "just" MySQL as the default database engine, while still allowing other engines to be used (https://governance.openstack.org/tc/resolutions/20170613-postgresql-status.…) Or labeling certain options as "experimental" as Neutron just did with "linuxbridge" (https://docs.openstack.org/neutron/latest//admin/config-experimental-framew…) or cinder with naming drivers unsupported (https://docs.openstack.org/cinder/ussuri/drivers-all-about.html#unsupported…) My point is that just having all those backends and no active guidance might make Tooz a very open and flexible component. I myself would wish for some less confusion around this topic and having a little less to think about this myself. Maybe the "selection" of Zookeeper by openstack-ansible is just that? I would love to hear your thoughts on coordination and why and how you ended up with using what. And certainly what your opinion on the matter of a stronger communicated "default" is. Thanks for your time and thoughts! Christian

[tacker][ptg] Antelope PTG Summary
by Yasufumi Ogawa 28 Oct '22

28 Oct '22

Hi all, We had great PTG sessions in Tacker team, and hopefully all. This is a summary of what we discussed during our sessions in three days. All of items and the results of discussion is here [1]. Day 1 (18 Oct 2022) 1. Reducing resources for FTs - We shared suggestions for fixing critical issues in functional tests in which we've had some unreasonable failures, especially at the end of releases. - Removing/deprecating unecessary legacy features and its tests. - Quick analysis for the failures [1]. - Wishlist for the item [2]. - Agree to focus on jobs has the large num of failures to revise tests. 2. Support tacker-db-manage for Multi DB backend - Support for PostgreSQL doesn't work, for insatnce, some issues in tacker-db-manage. - We agreed to not only fix the issues, but also take care other backends. - Revise tacker-db-manage for supporting multi DB backend. Start to support Postgres in antelope first, and other ones in the next releases then. - Proposed design is not so mature for now, so continue to discuss to revise. 3. Migrate OpenStack testing from Ubuntu Focal (20.04) to Ubuntu Jammy (22.04) - We agreed to migrate Focal to Jammy Ubuntu release as one of the community goal in this release [4]. - Candidate patches for the update have already proposed by manpreetk not only for tackder but also other releated projs. - https://review.opendev.org/c/openstack/tacker/+/861137 - https://review.opendev.org/c/openstack/tacker-horizon/+/861571 - https://review.opendev.org/c/openstack/python-tackerclient/+/861572 - https://review.opendev.org/c/openstack/tosca-parser/+/861136 - https://review.opendev.org/c/openstack/heat-translator/+/861158 https://etherpad.opendev.org/p/migrate-to-jammy 4. Bug Triage in Tacker - Add item of bug triage in IRC etherpad to discuss about bug triage. Day 2 (19 Oct 2022) 1. Operator Hour - Guys from KDDI and NTT Docomo joined and proposed their proposals as telcom operators [5]. 1.1. Support of redanduncy - For availability, essential to make Tacker redundant for commercial use, but less than we expected for the current impl. - What is the tacker specific consideration point is store VNF packages. 1.2. Error handling and recovering operation - More tests for changing error status, disaster recovery are required. 1.3. Detailed logs - Not enough log messages especially for management drivers. - Error message in tacker-server.log and tacker-conductor.log is usefull and enough for vnfm-admin, but like openstack vnflcm op show comannd and api's information is not enough for vnfm-user. 1.4. Roadmap - Having explicit roadmap is helpful for oprators to be interested. - Comply with ETSI NFV Rel4 is one of the good example for the direction. 2. Add sample coordinate VNF script using coordination API - We agreed to implement interfaces ETSI NFV SOL002 v3.5.1 defines the Coordination VNF interface for coordination with external management components. 3. Revise automatic operation state transition for N-Act configuration - v2API has a function to automatically transition opocc in an intermediate state to the final state when the tacker-conductor starts up, to recover inoperable opocc in the PROCESSING state by conductor down. - It causes a problem in N-Act setting. The opocc which are being handled by other working conductors are also automatically transitioned to the final state. We propose solutions for limiting opocc to be transitioned to those handled by the downed conductor. 4. Set different number of instances for same delta and aspectId - Fix overwriting the value for same aspect and delta id. - Multi VDUs Scale of V1 API isn’t supported by the issue. 5. Continue to update the remaining patch from Zed version - Move forward reviews on gerrit. Day 3 (20 Oct 2022) 1. Enhancement of Tacker API Resource Access Policy - Current Tacker policy control access to API resources by default role such as admin or any only. - We propose Fine-grained API resource access management based on user and VNF information according to operator usecases. 2. Secure RBAC: Implement support for project-reader persona in Tacker - As per the TC and community wide goal, next cycle 2023.1 is the must for all projects to implement the phase-1 (project personas). Plan to do it in Tacker in 2023.1 cycle will be helpful in community wide goal [6][7]. - Conclusions: Clarify conflicts can be caused while introducing new roles of S-RBAC to implement the fine grained APIs 3. Support Tacker auto-scale and auto-heal without NFVO (k_fukaya) - Zed release supported, Fault Management/ Performance Management(FM/PM) interfaces, and AutoHeal and AutoScale with external monitoring. However, Heal or Scale execution must be triggered by NFVO. This feature proposes implementing support receiving alerts from external monitoring tools, which can be VNFM driven AutoHeal and AutoScale without NFVO. 4. Discuss Tacker support versions and updates for K8s/Helm/Prometheus - The support versions in Antelope should be determined, as some versions may be inconsistent and support may expire before release. Considering the support period and development risk, it seems good to decide on the following. - k8s : 1.25 (current latest version) - helm : 3.10 (current latest version) - prometheus : 2.42 (next LTS version) - Update test patch for k8s 1.25.2 and helm 3.10.1 - https://review.opendev.org/c/openstack/tacker/+/860633 (Zuul +1) - Add version information under user guide. 5. AWS vim support - Add support for EC2 as VIM for the first step for AWS. - Whole discussion is here [8]. 6. Marking Deprecated and obsoleting of Legacy API - Should start to discussion about deprecation and obsoleting Legacy Tacker API (excluding VIM feature). - Deprecation process should follow as "Deprecation Guidelines" [9]. - The key point is - APIs should be marked deprecated before obsoleting and should be marked for at least 12 months. - An email thread will be started on openstack-discuss to determine how many people are using the deprecated API. - We will continue our discussion and move towards removing the Legacy API (excluding VIM feature).

[Ceilometer] RADOS GW metrics : cannot get radosgw.objects.size metric
by Taltavull Jean-François 28 Oct '22

28 Oct '22

Hello, I'm trying to get the 'radosgw.objects.size' metric, that is the total bucket objects size per tenant. I expected to get one sample per tenant but I get one sample per bucket instead, as with the 'rados.containers.objects.size' metric. Here is my pollster definition: ''' - name: "radosgw.objects.size" sample_type: "gauge" unit: "B" value_attribute: ". | value['usage'] | value.get('rgw.main',{'size':0}) | value['size']" url_path: "FQDN/admin/bucket?stats=True" module: "awsauth" authentication_object: "S3Auth" authentication_parameters: my_access_key,my_secret_key,FQDN user_id_attribute: "owner | value.split('$') | value[0]" project_id_attribute: "tenant" resource_id_attribute: "id" ''' I tried with "resource_id_attribute: "tenant" but it does not work better. Any idea ? Is there something wrong in the pollster definition ? Regards, Jean-Francois

[openstack-ansible][ptg] Antelope PTG results
by Dmitriy Rabotyagov 27 Oct '22

27 Oct '22

Hi everyone! As you might know, the OpenStack-Ansible team had Project Team Gathering on October 18, 2022 and we had quite good discussions. This email is a relatively short sum-up of decisions that were taken during it: * Add Zookepeer cluster deployment as coordination service. Coordination is required if you want to have active/active cinder-volume setup and also actively used by other projects, like Octavia or Designate. Zookeeper will be deployed in a separate set of containers for LXC path * Move out Ubuntu Jammy from experimental state except Ceph integration. This is because community repo does not have ceph packages built for Ubuntu 22.04, so we will switch default to use Ubuntu's native repository to get ceph from. With that you won't be able to pick what ceph version to use, but it will work for most usecases. * Continue supporting Ubuntu Focal (20.04) until Antelope release as upgrade path from Yoga to Antelope should exist and on TC PTG it was decided that it should be tested by projects on Ubuntu 20.04. * Update docs regarding level of support for integrated ceph-ansible deployment with openstack-ansible to address expectations on upgrade path. * Address concerns regarding Glance configuration with COW backends, with regards to OSSN notice: https://wiki.openstack.org/wiki/OSSN/OSSN-0090 * Switch distro path to experimental due to lack of maintainers. We should document that and mention that help is needed to keep it alive. If not - the feature can be removed in the future. * Cover OVN with TLS encryption. Leverage PKI role for that. * We also agreed to switch the default network driver used by OpenStack-Ansible to OVN as default. However, at the moment there is not much hands-on experience on OVN from the core team, so we can not switch default right now as we won't be efficiently helping with OVN deployments. So following switching plan was defined: ** Document reference OVN architecture that we are going to provide ** Document implementation of extra networks that are required for octavia, trove, etc. ** Switch AIO to OVN as default ** Add LXB jobs to neutron role ** Switch default for non-AIO ** Ensure that users who were relying on previous default (and using LXB) have proper override during upgrade. * Improve documentation for the Ironic role with adding a couple of scenarios. * Convert our dynamic inventory to an inventory plugin which will be installed during ansible bootstrap. * Create a repository for the skyline role. We are allowed to take https://github.com/jrosser/openstack-ansible-os_skyline as base and move it under openstack-ansible umbrella * Simplify documentation regarding provider_networks in openstack_user_config and suggest using neutron_provider_networks instead. * Continue working on improving our CI coverage, including returning to molecule testing but rely on the ansible and constraints version from the integrated repo. At the same time finish cleanup of old functional tests, including run_tests.sh, tox, etc. * Deprecate rsyslog_server/client roles as they are hardly used as of today. You can also check etherpad [1] where notes were taken during PTG and that we aim to update with progress on these points implementation: [1] https://etherpad.opendev.org/p/osa-antelope-ptg

[cinder] Problem with restoring purestorage volume backup
by Ришат Азизов 26 Oct '22

26 Oct '22

Hello! We have a problem with cinder-backup with cephbackup driver and volume on purestorage. When backing up purestorage volume with cinder-backup with cephbackup driver it creates in ceph pool and everything is ok. But when we try to restore the backup, it is not restored with an error "rbd.ImageNotFound" in the screenshot attached to this email. This happens because the original image is not in rbd, it is in purestorage. It is not clear why the cinder is trying to look for a disk in the ceph. Could you please help with this? Thanks. Regards.

[manila] Antelope PTG Summary
by Carlos Silva 25 Oct '22

25 Oct '22

Hello, Zorillas and interested stackers. Thank you for the productive PTG we had last week. Here goes the summary for the past week's discussions. In case you would like to see the expanded versions, please refer to [0] or check out the recordings in the Manila YouTube Channel [11]. Different approaches for the images we use in our jobs - Recent changes in the Manila CI (related to the service image) made the jobs take longer to run and become more resource intensive, causing jobs to fail more often due to lack of resources in dsvm - We have been looking for approaches to tackle this issue - In the short term, if a job keeps failing due to such issues, we will split it into two jobs - One to run scenario tests (these tests spawn VMs) - One to run API tests - We agreed that this can get worse in the future with dsvm images that could be even more resource demanding, and that we will look for containerized approaches to try and solve this issue Share backup - (kpdev) The proposed approach for share backup has changed - An existing specification [1] was restored - The idea is to have new APIs for share backup and a new generic Backup driver in a similar way to what Cinder does. - This would allow backends to have their specific implementations for share backups - Reviews for this specification are ongoing Secure RBAC changes - Goutham has shared with the community all the good progress we had in Manila, and also mentioned what we did in Zed, after all the operator's feedback. - Now, we are entering a phase where we want to test a lot! - We have a CI jobs and some test cases covered, but we still want to have more coverage - During Antelope, we will promote a hackathon in order to accelerate the functional tests coverage Outreachy Internships - On this topic, ashrodri, fmount, gouthamr and carloss shared the two proposed Outreachy project that are Manila related - ashrodri and fmount are proposing a project to have an intern creating a multi-node test environment with Devstack and Ceph [2], as these tests are becoming more resource demanding - carloss and gouthamr are proposing a project for an intern to work in Manila UI [3]. The idea is to close down the gap of features between Manila UI and the Manila API. OpenStackSDK Manila Status - This has been an effort for some time, and during the Zed cycle some code was merged for integrating share groups and share group snapshots. - This is a good candidate project for an internship, and the idea is that we will be able to get some interns working on this project (potentially a project for a college capstone project) OSC Updates - Zed was the release we targeted to reach feature parity with the native client, and we made it! - We had an idea to add a deprecation warning to the native manila client, but that will need to wait - There is still a missing bit for adding the deprecation warning: having version autonegotiation working, which is something we are targeting for Antelope - OSC is now the primary focus of the project when doing implementations for CLIs. Bandit Testing / VMT - The Manila team was introduced to the VMT (vulnerability management team) and Bandit, and we had contributors sharing their ideas around having manila under the VMT and running bandit tests. - VMT - The audience agreed with the conditions to be under the overseen repos. - Goutham has volunteered to be the security liaison for Manila - Bandit - There were some errors pointed out in a preliminar test run [4]. - We will add a bandit non-voting job and file bugs against third party drivers that have issues pointed out by the new job - New bugs will be filed and will be distributed across community members All Things CephFS - Ingress aware NFS Ganesha - Ceph Orchestrator is now capable of creating an ingress service to front-end a cluster of active-active NFS Ganesha instances via a single load-balanced IP address - Previously, we would only use one single instance of NFS Ganesha. This introduces a SPOF and is not suitable for production environments without HA being handled externally (like TripleO deployments do). With this change, Manila CephFS NFS users would be able to deploy multiple NFS Ganesha servers and leverage inbuilt HA capabilities - Currently though manila client restrictions (access rules) will not work since NFS-Ganesha sees the ingress service's IP instead of the client's IP address. - ffilz proposed his design to support the PROXY protocol with NFS-Ganesha. Ceph Ingress can pass the Client's IP address to NFS-Ganesha [5] - An alternative would be to have cephadm assign stable IP addresses to ganesha instances - No driver changes are anticipated in either approach - AI: Investigating deploying ceph-ingress with devstack - Migration tool for Manila with CephFS NFS - After the new helper was introduced to the driver, we are able to interact with cephadm-deployed CephNFS service (which comes with a lot of benefits) - Now, we need to figure out how to upgrade deployments with CephFS NFS using the current helper (which interacts with NFS Ganesha through DBUS) - There are two main issues: - Representing a change in exports when migrating across NFS Servers (current use case) or when decommissioning NFS Servers - Representing exports from multiple servers - a special case enabling migration where an old server will eventually be decommissioned: - These issues were talked through and possible solutions were proposed and will be worked on in the following cycles. More details on [6] - DHSS=True for CephFS driver - Currently, CephFS driver, whether you'd like to use it for Native CephFS, NFS via DBUS, NFS via ceph-mgr only supports DHSS=False. The request of this feature was raised during the OpenInfra Summit in Berlin from several Manila users. - We discussed some alternatives for making it happen: - 1) Operator determines Ceph cluster limits, and creates isolated file systems and declares multiple manila backends with each filesystem - 2) Subvolume groups - pinning a subvolume group to mds can isolate/dedicate mds load - CephFS CI issues - The lack of resources in the dsvms is affecting the CephFS Native and NFS jobs, causing them to be unstable. The jobs often run into timeouts - The situation could get worse as Jammy Jellyfish packages are not available yet - We will ask the ceph-users if jammy release bits can be made available Oversubscription enhancements - Storage pools supporting thin provisioning are open to oversubscription. This caused some problems mentioned in [7]. - We have an open specification which we intend to merge in the Antelope cycle, as well as the changes to address such issue FIPS - We have shared our testing status with regards to FIPS. We have jobs merged on stable branches up to wallaby for both manila and python-manilaclient repositories. - The next steps would be a more in-depth code audit to identify non-compliant libraries and making our jobs voting - We agreed to make our jobs voting when the Ubuntu images supporting FIPS are out - For drivers using non FIPS compliant libraries, we will notify the maintainers Metadata API update - Metadata APIs for share snapshots were added during the Zed cycle - The goal for this cycle is to have functional testing and the CLI merged. Both patches are under review and expected to be merged not late in the release. Manila CSI - The CSI plugin's been pretty stable in the last six months [8] - There was a good talk presented at KubeCon by Robert Vasek [9] - The next steps include getting a fix for an issue involving long snapshot names in the CephFS backend and supporting volume expansion in the OpenShift Manila CSI driver operator Manila Configuration of VLAN Network information - A issue was found where Contrail Neutron Plugin did not return the VLAN ID during port allocation [10] - To tackle this issue, we have agreed to add metadata to the share network APIs so the administrators would be able to add VLAN as metadata and drivers would be able to consume it. *Better use of bug statuses* - Our bugs were stuck in "New" instead of "Confirmed" or "Triaged" and this could be misleading. - We agreed to tag the bugs as confirmed or triaged depending on the outcome of our triaging and not leave bugs as "new" - We will ask the bug assignees to update their open bugs in case one of them has the new status, so we can have a better visibility [0] https://etherpad.opendev.org/p/antelope-ptg-manila [1] https://review.opendev.org/c/openstack/manila-specs/+/330306 [2] https://www.outreachy.org/outreachy-december-2022-internship-round/communit… [3] https://www.outreachy.org/outreachy-december-2022-internship-round/communit… [4] https://gist.github.com/gouthampacha/c0d96966670956761b2b620be730efe2 [5] https://docs.google.com/document/d/1orjNjtEeeyRrgvbQuFU5BdsCnZG9gF3MymDCZl-… [6] https://etherpad.opendev.org/p/antelope-ptg-manila-cephfs [7] https://etherpad.opendev.org/p/manila_oversubscription_enhancements [8] https://github.com/kubernetes/cloud-provider-openstack/commits/master/pkg/c… [9] https://www.youtube.com/watch?v=XfpP9pBTXfY&t=1145s [10] https://bugs.launchpad.net/charm-manila/+bug/1987315 [11] https://www.youtube.com/playlist?list=PLnpzT0InFrqBzbSP6lcYDStKpbEl3GNHK Thanks, carloss

[Glance] Antelope PTG Summary
by Pranali Deore 25 Oct '22

25 Oct '22

Hello Everyone, We had our sixth virtual PTG between 18th OCt to 21st OCT 2022. Thanks to everyone who joined the virtual PTG sessions. Using bluejeans app we had all the discussion around different topics for glance, glance + cinder, glance + ceph, fips and secure RBAC. I have created etherpad[1] with notes from the session and also included the recordings of each session. Here is the short summary of the discussions. Tuesday, OCT 18th 2022 # Zed Retrospective On the positive note, we have merged a number of useful features this cycle. We managed to implement glance-download internal plugin to download the image from remote glance, Implemented support for immediate caching of an image, Extended the functionality of stores-detail API to expose store details of other stores and we have removed the scope scheck from scope_types for all project resources and done with phase 1 as per the revised community goal. In addition to that we have successfully organized the review party before each milestone to perform group review to cover the review load till the final milestone. On the other side we decided to organize a midcycle general cross project meetup/drivers meetup towards the end of the 2nd milestone to increase our presence in cross-projects. Recording: https://bluejeans.com/s/II_@CAqrZdd - Chapter 1 # Distributed responsibilities among cores/team This cycle also we have decided to follow the distributed leadership internally, we are going to distribute below responsibilities among the team, Release management:pranali Bug management: cyril Meetings: pranali Stable branch management: cyril and Erno Cross project communication: abhishekk Mailing lists: share responsibility, pranali PTG/summit preparation:pranali Vulnerability management: glance-coresec group Infra management: periodic-jobs - abhishekk migration of test jobs -abhishekk Recording: https://bluejeans.com/s/II_@CAqrZdd - Chapter 2 # Default Glance to configure multiple stores Glance has deprecated single store configuration since Stein Cycle and this cycle we are going to start putting our efforts to deploy glance using multistore by default and then remove the single store support from glance. Recording: https://bluejeans.com/s/II_@CAqrZdd - Chapter 3 # Add missing CLI support for some Glance API in Openstack Client The CLI support for all glance APIS is already there in GlanceClient and the similar CLI support we need to have in OpenstackClient, in this Cycle we are going to put efforts to have OSC support for all the missing glance APIs. Recording: https://bluejeans.com/s/II_@CAqrZdd - Chapter 4 # Glance Cache improvements, restrict duplicate downloads This is abou how we can avoid multiple downloading of the same image in cache on first download Spec : https://review.opendev.org/c/openstack/glance-specs/+/734683 We had this spec in the last cycle & decided to break the image into chunks and when the first request gets to the backend store it will start caching that image and if any other request comes in between and if caching is still in process it will read from the chunks created by the first request. But currently we have made one caching state to check if the image is still in caching but that was relying on md checksum to check if the image iterator has read the image completely or not but in new images we might not have checksum, multihash or size of the image, bcz if that is not present with the image we won't be able to change the state of image and thus we will never be able to resolve the issue of checking the image is in caching or not. Decided to dig more on the size verification & need to revisit this topic during mid-cycle meeting and update the spec with the solution for handling the multiple request and multiple chunks Recording: https://bluejeans.com/s/II_@CAqrZdd - Chapter 5 Wednesday OCT 19th , 2022 # Image uploads to the filesystem driver are not fully atomic No efficient way to reproduce this issue, so it's decided to mark it as 'Won't fix' Recording: https://bluejeans.com/s/j_UgZFw_jEV - Chapter 1 # DB migration constant change handling Till now we have all the migration scripts by the name of the cycle and since currently release has been change to 2023.1 which is going to break the migration test because when our DB sync tool runs it will check the initial version liberty and it finds the migration script from the liberty and traverse through all the directories till the current release and executes all the scripts available in that path. Decided to fix this by updating the data migration current release to '2023.1' and check with actual migration script to check whether there is any regression or not and check if it executes the scripts in serial manner. Recording: https://bluejeans.com/s/j_UgZFw_jEV - Chapter 2 # Configurable Soft Delete Stephen initiated this topic for nova and oslo.db but also sent out a mail for glance, cinder and for other projects, if we would be interested in the idea https://lists.openstack.org/pipermail/openstack-discuss/2022-October/030729… But Glance replies a lot on soft delete and doesn't allow hard delete as glance allows the user to specify the UUID of the image , so it's part of a security promise of an immutable images that you are not able to delete an image and then recreate image with same UUID right after, hence soft delete model can't be removed from Glance. Recording: https://bluejeans.com/s/j_UgZFw_jEV - Chapter 3 # Secure RBAC As per the revised community goal, till zed cycle we must have the project prosona implementation & drop the system scope which we have already done in glance. We have implemented project scope for image apis in wallaby & in Xena we have managed to move all policy checks to API layer and implemented project scope of metadef APIs. During zed cycle, we had discussed that like which apis should be exposed to system scope but after the operators feedback & as per the revised community goal it was decided to drop the system scope, we just had to remove the scope scheck from scope_types for all project resources, so we are done with Phase 1. In Antelope Cycle glance is going to switch the new defaults flag ON, once it is verified by tempest for all the services. Recording: https://bluejeans.com/s/j_UgZFw_jEV - Chapter 4 # Image Export with Metadata This is about exporting images with associated metadata for importing into another Glance deployment. This cycle we need some volunteers to work on this, the glance team will help in terms of reviews/finalizing the design etc otherwise we will revisit this in the next cycle. This session was not recorded as it was a small discussion # Fips Overview Path forward: - Investigate on the time outing of the existing glance fips job - Try to do the centos9 jobs stable till wallaby, so could possibly move to voting - Have ubuntu jobs working & running and make them stable Recording: https://bluejeans.com/s/j_UgZFw_jEV - Chapter 5 Thursday, OCT 20th, 2022 # Option needed to create image in erasure coded ceph pool To use the erasure coded ceph pool feature where the data will be held needs to be specified during image creation, a config option is needed. Decided to write a spec first describing this in detail and modify the existing devstack job for ceph. Recording: https://bluejeans.com/s/cNEJ@Yq_hv5 - Chapter 1 # Parallelization of RADOS image writes when creating an image This is for parallelization of image writes into ceph, by increasing the amount of data written at once. Decided to not have this without testing to measure if there's an actual gain. Recording: https://bluejeans.com/s/cNEJ@Yq_hv5 - Chapter 2 # Add chunk download support for rbd backend Rbd supports random reading, and the rbd driver is designed to support partial download. But the current version disables this feature, and doesn't implement the chunk support. There is potential future use for it, but there's nothing that users would gain from this. If not usable through the API then we will drop this. Recording: https://bluejeans.com/s/cNEJ@Yq_hv5 - chapter 3 # Operators hour No operator joined the session # Speedup upload images for Swift backend Upload images using Swift backend is slow due to the synchronous way of uploading fragments and which causes loading that can take several hours, especially in cases with very large images. Decided to update the spec with two implementations one as traditional & one for multithreaded one, by having a new configuration option ``swift_store_thread_pool_size`` to the Swift store backend. Recording: https://bluejeans.com/s/cNEJ@Yq_hv5 - Chapter 4 Friday, OCT 21st, 2022 # Cross project meet with Cinder # Glance Image Direct URL access Issue Glance has OSSN-0090[2] describing the security risk when you are operating glance with 'show_multiple_locations' or if the end user facing glance-api has 'show_image_direct_url' options set to true. When glance shares a common storage backend with nova & cinder, it is possible to open some known attack vendors by which malicious data modification can occur. Decided to fix this by going with the solution proposed by Rajat during last cycle, to remove the show_multiple_locations config option and to have below 2 new location APIs[3] which will replace the image-update mechanism for consumers like cinder and nova in glance, 1. Location ADD API: Design this api in way that the location will be added only once during image create when the image is in QUEUED state and no-one should be allowed to add location after the image is active This wouldn't require the 'service role' and a basic check on the glance side to check image status should suffice. 2. Location GET API: This will show all the locations associated with an existing image. Returns an empty list if an image contains no locations. This would still require the 'service role' since we don't want to expose locations to end users. Glance has dependency on keystone for 'service role' which is going to be implemented in this cycle as per phase 2 target mentioned in SRBAC community goals[4]. Recording : https://bluejeans.com/s/B4Rlifuwx_l - Chapter 1 You will find the detailed information about the same in the PTG etherpad[1] along with the recordings of the sessions and milestone wise priorities at the bottom of the etherpad.

[kolla] [train] Endpoints fail when one controller is down
by Albert Braden 25 Oct '22

25 Oct '22

Some of our clusters are heavily used, and in those clusters we get complaints when we reboot a controller (or sometimes when we deploy and containers restart). Is that normal, or does it mean that we have something configured wrong? The symptoms are intermittent 504 from endpoints, and VM creation/deletion failing or partially completing, for example the VM is created but without DNS records. We are not following the "Removing existing controllers" procedure [1] before rebooting the controller; is that necessary to avoid these issues? 1. https://docs.openstack.org/kolla-ansible/latest/user/adding-and-removing-ho…

[TripleO] 2023.1 Antelope PTG summary
by Rabi Mishra 25 Oct '22

25 Oct '22

Hi All, Hope y'all had a great PTG last week and a great weekend. I would like to thank everyone who participated/contributed to Tripleo PTG sessions and helped all of us "share and learn". Though personally I don't like long emails, this summary is going to be a bit longer, please bear with me. We had a total of ten sessions spread over two days with very good participation (most sessions with 35+ [max 44] in attendance) and we shared/ discussed a multitude of topics. # Welcome and Zed Retrospective The highlights of the Zed cycle was collaboration across teams to add some new features and fine-tune features implemented in previous cycles that includes; Standalone roles, nftables switch, OVN RAFT support, ephemeral heat for upgrade use cases, CI jobs for Deployed Ceph and Ceph Container Promotion in CI etc. There was a discussion on the suggestion to stop backporting feature removals from stable branches as we did for wallaby in the last few cycles. Though TripleO does not follow stable policy, backporting feature removals with dependent patches across repos more often than not leads to broken CI and user support cases. We would be well placed if we can identify and do those before zed release and avoid the firefighting later. [Action Items] - Update zed review priorities etherpad[1] with deprecation/removal patches [All] # Standalone Ansible Roles Status Update James provided an update on the current status of "Standalone Ansible Roles' POC and we discussed the possible future scope of it beyond the current "scale-out compute" use case. He also demoed molecule based automation of deploying/testing a compute node with the new meta-role. Chandan shared the current work on CI jobs/scenarios to deploy computes with standalone roles. [Action Items] - Prioritize review/merge of proposed patches[2] on this topic [tripleo-core] - Finish the CI jobs for testing standalone roles and make them voting [Chandan/tripleo-ci-core] # Standalone Ansible Roles and External Ceph John presented his work to integrate computes deployed with standalone roles with external ceph. We don't plan to extend this effort to include tripleo deploying ceph using standalone roles, unless there is a requirement for that in the future. [Action Items] - Prioritize review of ceph related standalone role patches.[tripleo-core] # Multi-rhel support for Compute Brendan gave an update on the ongoing effort for multi-rhel support, different options evaluated and current POC status with composable roles approach. There is still some work left on automating role split during upgrade, which is expected to be completed this cycle. [Action Items] - Finish composable roles POC and test upgrade procedure manually [upgrades team] - Add CI jobs to test the proposed procedure upstream as feasible [upgrades team] - Implement role-split automation during upgrade [Takashi/Rabi] # OpenStack SDK, Ansible Collections OpenStack and TripleO We discussed the issues around openstacksdk backward incompatibility and the current pinning for it in RDO/TripleO. We agreed on an action plan to pre-release ansible-openstack-collection (AOC) for RDO/TripleO (though it is still not fully compatible with latest openstacksdk) and remove the pin so that Zed RDO can be released with openstacksdk 0.101.0. [Action Items] - Bump openstacksdk to 0.101.0 for RDO master and zed [Jakob/Alfredo] - Update RDO ansible-collections-openstack to the 2.0.0 pre-release [Jakob/Alfredo] # TripleO and Distributed Project Leadership (DPL) In this session, we discussed the possibility of opting for DPL in TripleO and sharing the responsibilities across multiple leaders in the team. There were a number of volunteers for different liaison roles and we in general agreed that it would be a good thing to do. We would propose the required change to governance sometime this cycle, unless there is any concern. [Action Items] - Finalize all required liaison roles and propose patch to openstack governance repo [Rabi] # Migration from puppetlabs/apache As part of the broader effort to reduce the puppet footprint, Cedric presented the ongoing effort to replace puppetlabs/apache with the new ansible role "tripleo_httpd_vhost"[3]. A few services have already been migrated and remaining ones are expected to be done this cycle with broader participation from sub teams. [Action Items] - Review/merge the already proposed patches for migration [tripleo-core] - Plan and work on migrating remaining services [Cedric] # State of CI CI team presented on a vast range of topics that included, - Added coverage of upgrade jobs across upstream check/gate, periodic component pipeline and periodic integration pipeline in zed (Marios) - Upstream jobs for multi-rhel testing (Marios) - Current state of OVB Jobs (Chandan) - TripleO CI Jobs on IBM Cloud and the new feature to hold nodes for troubleshooting (Chandan) - Tempest Allow List (Arx/Pooja/Soniya) - Tempest Dashboard (Arx/Lukas) # Container Capabilities We revisited the topic of privileged containers for services and how we can possibly avoid those by allowing the required limited container capabilities. As all these services are mostly for the compute role, we agreed that it would probably be better to align this effort with "Standalone Roles" for better testing. # OS Migrate Status Update Jirka provided an update on the tenant migration tool 'os-migrate', an ansible collection that is not a TripleO umbrella project, but used by the upgrades team. It's possible that I missed some important points from these discussions. Please feel free to add them by replying to this thread. All session etherpad links are in the main schedule etherpad[4] for reference. I'll share the session recordings once they're made available to us. Thanks Again.

[cloudkitty] Antelope PTG summary
by Rafael Weingärtner 25 Oct '22

25 Oct '22

Dear all, The CloudKitty project had a great PTG meeting. Thanks to the OpenInfra Foundation for holding it. Also, thanks to all who have dedicated precious time to attend. We started the meeting by revisiting the latest release and discussing the review format we have adopted in the past two years. Looking at the result of our process, we decided to maintain it, as it seems to bring results and concentrate our efforts on getting CloudKitty better and evolving throughout time. While reviewing the past release, we discussed the situation with patch [1] (Allow rating rules that have 12 digits in the integer part of the number). This patch is a bug fix, and we discussed the idea of backporting it. However, as it is a patch that affects the database schema, it can be troublesome to backport it. Therefore, before doing any work, we will consult the mailing list to gather others opinions on this matter. Users could upgrade CloudKitty to address this issue, if they need to, instead of applying a patch. Pierre volunteered to execute this "inquiry" with the CloudKitty user base in the mailing list. While discussing the ElasticSearch (ES) improvements in CloudKitty to support ES 7, we raised the concern that Kolla-ansible is moving from ElasticSearch to OpenSearch. Therefore, we need to evaluate if this can have an impact in CloudKitty. Most certainly it will impact people using ES as the backend. The goal is to revisit this discussion in our next bi-weekly meeting, and then communicate for users and community (Topics for meeting of 31/10/2022 [2]). Furthermore, as the current CloudKitty team is a bit small, we have decided to focus on the following topics for the Antelope cycle. - Multiple rating types for the same metric -- One metric being used to generate different rates - Different time frame group by options -- provide group by options to group by day of the year, week of the year, month, and year. - Improve some timeouts handling when using Gnocchi backends. This one needs some checking with Zigo, who was the one that reported this situation. Zigo, I added you to this e-mail, can you reply back with more details regarding this situation? - A regression API that takes the resource ID Or project ID or scope ID, and executes a regression (prediction) based on the collected data so far for the given resources/elements/scope. - Add CloudKitty API reference docs ( https://docs.openstack.org/cloudkitty/latest/api-reference/index.html) to https://docs.openstack.org/api-ref/ We also briefly discussed the situation with Monasca, which has already been deprecated from Kolla-ansible, and might be losing some traction and support. Therefore, we (as a community), might need to start thinking about deprecating it, and removing some non-tested code from our code base. We do understand that deprecating and removing support is complicated for users, but nobody is maintaining and testing that integration. Therefore, it tends to get broken and unstable over time. However, if somebody wants to volunteer to maintain and improve it, you are welcome :) In summary that is the outcome of our small, but efficient PTG meeting. Let's keep improving and making CloudKitty better. If I missed something, please do not hesitate to reply back. Also, if somebody needs any help, you can always ping me :) See you guys. Have a nice week! [1] https://review.opendev.org/c/openstack/cloudkitty/+/837200 [2] https://etherpad.opendev.org/p/cloudkitty-meeting-topics -- Rafael Weingärtner

[neutron] Antelope PTG summary
by Rodolfo Alonso Hernandez 25 Oct '22

25 Oct '22

Hello Neutrinos: This is a quick summary of what we have discussed during the PTG week. Zed summary and retrospective: - Here is the output of this session: https://etherpad.opendev.org/p/neutron-antelope-ptg#L83 Spec handling: - To have a core reviewer assigned per spec. This reviewer will engage the community to review the spec and will be a kind of "godfather". - To have a weekly status report of the active specs in the community, to visibilize them, boost their impact and "coerce" the community to review them. Neutron CLI deprecation: - To remove the CLI code. - Python bindings: - Investigate and report the effort needed to make this migration in neutron client consumers (Nova, Horizon, Heat, etc). - Request other projects using the python bindings to move to OpenStack SDK. - Stop merging new features. Quota classes: - Information: https://docs.openstack.org/project-team-guide/technical-guides/unified-limi… - Neutron RFE: https://bugs.launchpad.net/neutron/+bug/1993288 - Still under development in the community, this is still not an accepted community goal, thus we won't start the development until some cons are discussed with the TC members (see the Neutron RFE description). Pyroute2 session: - IPmock, a new class to mock some pyroute2 objects: https://lab.pyroute2.org/ - Pluggable netlink engines. Still not compatible with NetNS (namespaces) - Transactional engine: - A daemon is always reading the netlink and inotify, and builds a DB with the system information. Data is read faster. This could be not compatible with the current sync calls using privsep. - Using NDB class. - Customize message parser, to reduce the amount of data retrieved from the kernel. - Dump/list operators will be generators (to check the compatibility with privsep). Remove the failed devstack migration and get back to what is called "neutron-legacy" (that was discussed before in a PTG but we didn't start the reversion). DNS subdomain support in ML2/OVN: - https://review.opendev.org/c/openstack/neutron-specs/+/832658 - On hold until there is a use case. DNS resolver in ML2/OVN: - https://bugzilla.redhat.com/show_bug.cgi?id=2104568 - The main devoplment part falls in the OVN core team. Once finished, the Neutron part should be almost trivial. ML2/OVN flow metering. - Same as we currently have with ML2/OVS + iptables firewall (currently not supported with native firewall because we can't count OF flows). - Same as the previous feature, the main development is in the OVN core team. Neutron QA: - Implement a grenade job based on the SLURP cadence, testing from Y to A (done). - Have the "tempest-integrated-networking" job in our gate/check queues (patch under review). PCI Device Tracking In Placement (Nova-Neutron session): - The different approaches are still under development. - Spec to be proposed during this release (see etherpad to check the possible implementation options). Port binding switchdev capabilities (Nova-Neutron session): - We agreed that the current implementation is incorrect: Neutron should not modify the port binding dictionary. Nova is not reading it but overwriting it. - We won't change the current code but no new features will rely on it. Nova mutable MTU support (Nova-Neutron session): - For now, Neutron will document that a network MTU change requires a VM reboot (ot port detach/attach operations) to be applied on this port. S-RBAC: - Neutron has three implemented personas: system wide admin, project user and project reader. - Tempest will integrate all RBAC testing projects during this release. Once done, the new RBAC flag will be enabled by default. - Neutron will create the corresponding RBAC job/jobs. - Neutron needs to identify what is called "service role" calls (done from other projects). This is a new concept that will be included in next releases. nftables migration: - The current iptables legacy interface could be deprecated. During this release, Neutron will start an epic to move the current iptables API to the new nftables API; if possible, incrementally, mixing both APIs in the same agent. Please, if there is any missing topic, let me know. Regards and thank you for attending and participating.

[Cinder][Nova]Zombie process prevention for Cinder and Nova APIs
by yu-kishimoto＠kddi.com 24 Oct '22

24 Oct '22

Hi all, I'm trying to fix issues of spawning zombie processes for Cinder and Nova APIs during instantiation in an IaC (Ansible which is not openstack-ansible). Does someone can kindly help me to solve the issue or give me some clues like parameter changes that can be expected to be effective? - Issues The cinder api service process(port: 8776) existed in a zombie state. The neutron api service process(port: 9696) required for nova existed in a zombie state. - What the IaC does Use an existing tenant to create a network and subnet, then use 8volumes to instantiate 8VMs. - Workarounds and what I've done so far Identify and kill zombie processes. - Environment OS: CentOS Stream 8 Kernel: 4.18.0-408.el8.x86_64 OpenStack: Yoga(Deployed by PackStack: https://www.rdoproject.org/install/packstack/) Nova: 25.0.1 Neutron: 20.2.0 Cinder: 20.0.1 KeyStone: 21.0.0 -- Yukihiro Kishimoto Technologist KDDI Co., Ltd.

[magnum] Antelope PTG summary
by Jake Yip 24 Oct '22

24 Oct '22

Dear all, Magnum had a great meeting during the latest PTG. Thanks to OpenInfra Foundation for holding it. Also, thanks to all who has found precious time to attend. As the current Magnum team is quite small, we have decided on the following: - Deprecate the Fedora Atomic driver - This is EOL. - Deprecate the CoreOS driver - This is similarly EOL. - Deprecate the Docker Swarm driver. Kubernetes has became the container orchestration engine of choice now. With our limited resources, it will be more efficient to support the most popular choice well, instead of multiple choices. - Mark branches before Victoria as unmaintained. These branches only support Kubernetes versions that has been EOL. - Most excitingly, move towards adding Cluster API support for Kubernetes. This allows the Magnum project to leverage off upstream effort in creating and managing a Kubernetes cluster. We understand that removing support is difficult for users, but we believe this is for the better. Our main aim is to keep the project moving fast enough to keep up with upstream Kubernetes. If anyone is willing to help maintain any of the items we plan on deprecating, please drop me a message. Regards, Magnum Team. -- Jake Yip DevOps Engineer, ARDC Nectar Research Cloud

[nova][placement] 2023.1 Antelope PTG summary
by Sylvain Bauza 24 Oct '22

24 Oct '22

We're on a wetty Monday here and I guess this is time for me to take my pen again and write a PTG recap email for the current release, which is 2023.1 Antelope. Yet again, I *beg* you to *not* use any translation tool when reading any etherpad, including Google Chrome embedded translation or it would fully translate the whole etherpad content for *all* readers. In order to prevent any accidental misusage, here is a readonly copy of the Nova etherpad we had for the week https://etherpad.opendev.org/p/r.8ae4e0ef997aebfe626b2b272ff23f1b Again, I'm human and while I can write bugs (actually I write a lot of them), I can also write wrong things in this email and I can misinterpretate something precise. Apologies if so, and please don't refrain them yourself to correct me by replying to this email. Last but not the least, I'm more than open to any questions or remarks that would come from the reading of this long email. Good luck with this very long thread, you should maybe grab a coffee before starting to read it (and I promise to keep it as short as I can). ### Operator hours ### After the success of the productive Nova meet-and-greet session we held in Berlin (packed room w/ lots of feedback), we were eager to again have a discussion with operators, this time virtually which would have hopefully lowered the entry barrier by not requiring an in-person event in order to attend the session. Consequently, we allocated three timeslots of one hour, two back-to-back on Tuesday and one on Wednesday (on different times to arrange time differences between operators). Unfortunately, I have to write here that we only had a very small attendance on Tuesday with only three operators joining (but providing great feedback, thanks btw. !) and *none* on the 1-hour Wednesday slot. As a result, I won't provide statistics about release and project usage here as numbers are too low to be representative, but here is what we discussed : (again, a readonly etherpad is available here https://etherpad.opendev.org/p/r.aa8b12b385297b455138d35172698d48 for further context) # Upcoming features and general discussions - the possibility to mount Manila shares in Nova seems promising. - As nova doesn't support multiple physnets per neutron network today, this prevents the use of routed networks in some cases. - modifying our mod_wsgi usage to be allowed to pass some arguments is requested - operators seem interested in having PCI devices tracked in Placement # Pain points - getting inventories or used/availables resources in Placement becomes costly as it requires N calls, with N be the number of Resource Providers (instead of a single HTTP call). Problem has been acknowledged by the team and some design discussion occurred. - We should paginate on the flavors API and we need to fix the private > public flavor bug. - mediated devices disappearing at reboot is a problem. This has been discussed during the contributor session later, see below. - routing metrics are hard to manage when you have a long list of multiple ports attached. We eventually agreed on the fact the proposal fix could be an interesting feature for Neutron team to develop. That's it for the operators discussions. Let's now discuss about what we discussed in the contributors PTG agenda : ### Cross-project discussions Two projects this time were discussing with the Nova community : # Ironic-Nova The whole session was about the inconsistencies that were happening if a nova-compute was failing down with Ironic rebalancing the nodes. - we agreed on the fact this wasn't an easy problem to solve - a consensus was around the fact Ironic should support a sharding key so the Nova compute could use it instead of using hash rings. - JayF and johnthetubayguy agreed on codifying this idea into a spec - we'd hear feedback from operators about what they feel of the above migration (sharding their node cloud into sharding pieces and providing sharding details to nova) - in parallel of the above, documentation has to be amended in order to recommend for *existing deployments* to setup active/passive failover mode for Nova computes (instead of relying on hashring rebalances) # Neutron-Nova (I'll briefly cover the details here, as it will also be covered by the Neutron PTG recap) - while Nova is finishing up tracking of PCI devices in Placement this cycle, we agreed on defering the modeling of Neutron-based PCI requests until next cycle. This won't have any impact in terms of existing features that will continue to operate seamlessly. - the way we define switchdev capabilities as of now is incorrect. We agreed on modfying Nova to allow it to report such capabilities to Neutron. This may be a specless blueprint or just a bugfix (and then potential backportability), to be determined later. - MTUs are unfortunately immutable. If you change the MTU value by Neutron, you need to restart the instance( (or reattach the port). We consequently agreed on documenting this caveat, which is due to libvirt/qemu not able to change the MTU while the guest is running. - We eventually agreed on letting --hostname (parameter of an instance creation request) to represent a FQDN thru a nova microversion. This value won't be sanitized by nova and directly passed to Neutron as the hostname value. We also agreed on the fact Nova WON'T ever touch the port domain value in metadata, as this is not in the project scope to manage name domains. ### Procedural discussions (skip it if you're not interacting with the Nova contributors) ### # Zed retrospective - We had a productive Zed release and we made a good job on reducing bugs and bug reports. Kudos to the team again. - The microversions etherpad we had was nice but planning microversions usage is hard. WE agreed on rather providing a document to contributors explaining them how to write an API change that adds a new microversion and how to easily rebase this change if a merge conflict occurs (due to the micoversion being taken by another patch that merged) - We agreed on keeping an etherpad for tracking all API changes during milestone-3 - We agreed on filing blueprints for TC goals that impact Nova - bauzas will promote again the use of review-priority label in Gerrit during weekly meetings in order for cores to show their interest in reviewing a particular patch. # Promoting backlog features to new contributors and enhance mentoring - Starting this cycle, we'll put our list of small and easily actionable blueprints into Launchpad bug reports that have a "Wishlist" status and both a 'low-hanging-fruit' and a 'rfe' tag. New contributors or people wanting to mentor a new upstream member are more than welcome to consume that list of 'rfe' bugs and identify the ones they're willing to work on. A detailed process will be documented for helping newcomers to join. - We'll also draft our pile of work we defer into 'backlog specs' if they require further design (and are less actionable from a newcomer perspective) # Other procedural and release discussions - we'll stop using Storyboard for tracking Placement features and bugs and we'll pivot back to Launchpad for the 'placement' sub-project. - we agreed on a *feature* review day possibly 4 weeks before the feature freeze in order to catch up any late design issue we could have missed when reviewing the spec. - we will EOL stein and older nova branches with elodilles proposing the deletion patch. We agred on discussing EOL'ing train at next PTG. - gibi will work on providing a static requirements file for nova that would use minimum versions of our dependencies (non transitively) and modify unit and functional test jobs to rather use this capped requirements file for testing. - we discussed the User Survey and we agreed on discussing any question we may want to add in the next survey during the next weekly meetings. - "2023.1 Antelope" naming is a bit confusing, but we agreed on we should continue to either use "2023.1" or "2023.1 Antelope" for naming our docs. We also wait for guidelines in order to consistently name our next stable branch (2023.1 possibly). (That's the end of procedural and release discussions, please resume here if you skipped the above) ### Technical bits ### # VMware driver status - As currently no job runs happened since April, we agreed on communicating in the nova-compute logs at periodic times that the code isn't tested so operators running it would know its upstream status. - we'll update the supported matrix documentation to refiect this 'UNTESTED' state # TC goals this cycle - for the FIPS goal, we agreed on the fact the current FIPS job (running on centos 9 stream) shouldn't be running on gate and check pipelines. As the current job is busted (all periodic runs go into TIMEOUT state), we also want to modify the job timeout to allow 30 mins more time for running (due to a reboot in the job definition) - for the oslo.privsep goal, no effort is required from a nova perspective (all deliverables are already using privsep). sean-k-mooney can propose a 'rfe' bug (see the note above on new contributors) for modifying our privsep usage in nova (using different privsep context by callers) - for the Ubunutu 2022.4 goal, gmann already provided changes. We need to review them. - for the RBAC goal, let's discuss it in a proper section just below # Next steps on RBAC - we need to test new policy defaults in a full integrated tempest testsuite (meaning with other projects), ideally before the first milestone. - once we check everything works fine as expected, we can flip the default (enabling new policies) before milestone-2 - we'd like to start drafting the new service role usage by two new specs (one for nova, the other one for placement) # Power management in Nova A pile of work I'm proud we gonna start this cycle. This is about disabling/enabling cores on purpose, so power savings occur. - we agreed on supporting it directly in Nova (and to not design and support an external tool which would suppose to draft some heave interface for an easy quickwin). This would just be a config flag to turn on that would enable CPU cores on demand. - a potential follow-up *may* be to use a different CPU governor depending on flavors or images but this won't be scoped for this release. # Power monitoring in Nova I don't really like this name, as monitoring isn't part of the Nova mission statement so I'll clarify. Here, this is about providing an internal readonly interface for power monitoring tools running on guests that would be able to capture host consumption metrics. One example of such monitoring tools is Scaphandre, demonstrated during the last OpenInfraSummit at a keynote. - we agreed on reusing virtiofs support we're gonna introduce in this release for the Manila share attachment usecase - this share would be readonly and would be unique per instance (ie. we wouldn't be supporting multiple guest agents reading different directories) - this share would be enabled thru a configuration flag per compute, and would only be mounted per instance by specific flavor or image extraspec/metadata. # Database soft-deleted records and the archive/purge commands - We don't want to deprecate DB soft-deleted records as some APIs continue to rely on those records. - We rather prefer to add a new parameter to the purge command that will directly delete the 'soft-deleted' records from the main DBs and not only the shadow tables (skipping the need to archive, if the operator wants to use this parameter) # Nova-compute failing at reboot due to vGPU missing devices Talking of bug #1900800, the problem is that mediated devices aren't persistent so nova-compute isn't able to respawn the instances after a reboot if those are vGPU-flavored. - we agreed on the fact that, like any other device, Nova shouldn't try to create them and we should rather ask the operator to pre-create the mediated devices, exaclty like we do for SR-IOV VFs. - we'll accordingly deprecate the mdev creation in the libvirt driver (but we'll continue to support it) and we'll log a warning if Nova has to create one mdev. - we'll change the nova-compute init script to raise a better exception explaining which mdev is missing - we'll document a procedure for explaining how to get existing mdev information and persist them by udev rules (for upgrade cases) # Robustify our compute hostname changes To be clear, at first step, we will continue to *NOT* support nova-compute hostname changes but we'll better detect the hostname change to prevent later issues. - first step to persist the compute UUID on disk seems a good candidate so a spec is targeted this cycle. - next steps could be to robustify our relationships between instance, compute node and service object records but this design will be deferred for later in a backlog spec. # Move to OpenStackClient and SDK OSC is already fully supported in Zed but it continues to rely on novaclient python bindings for calling the Nova API. - we agreed on modifying OSC to rather use openstacksdk (instead of novaclient) for communicating to the Nova APIs. Contributors welcome on this move. - we agreed on stopping to use project client libraries in nova services (eg. cinderclient used by nova-compute) and rather use openstacksdk directly. A 'rfe' bug per project client will be issued, anyone willing to work on it is welcome. - we also agreed on continuing to support novaclient for a couple of releases, as operators or other consumers of this package could require substantial efforts to move to the sdk. - we agreed on changing the release model for novaclient to be independent so we can release anytime we need. # Evacuate to target state We understand the usecase (evacuate an instance shouldn't always turn the evacuated instance on) - that said, we don't want to amend the API for passing a parameter as this would carry a tech debt indefinitely) - we prefer to propose a new microversion that would stop the instance eventually instead of starting it - operators wanting to keep the original behaviour would need to negociate an older microversion to the Nova API as we don't intend to make spawning optionally chosen by API on evacuate. (aaaaaaaaaaaaaaaand that's it for the PTG recap) Kudos, you were brave, you reached that point. Hope your coffee was good and now you feel rejuvenated. Anyway, time for me now to rest my fingers and to enjoy a deserved time off. As said, I'm all up for any questions or remarks that would come from the reading of this enormous thread. -Sylvain

[nova] Proposing EOL of nova project's old stable branches (Stein, Rocky, Queens)
by Elõd Illés 24 Oct '22

24 Oct '22

Hi, At the 2023.1 Antelope PTG, Nova team discussed that currently open Queens, Rocky and Stein branches for Nova teams' repositories will be moved to End of Life. There are multiple reasons behind this decision: - gate of these branches are broken for a couple of months now - zuul job definitions for these branches use the pre-"zuul-v3" [1] style, which makes the maintenance harder of these jobs - CI on Rocky and Queens use Ubuntu Xenial, which is also beyond its public maintenance window date And last but not least bugfix backports to these branches don't really get enough reviews anymore. If anyone has any interest to keep any of the above branches open then this is the last opportunity to step up, otherwise, as Nova team decided on the PTG, these branches will transition to End of Life. Please let us know before November 7th, we will proceed with the transition in case no responses will come till that day. [1] https://docs.openstack.org/project-team-guide/zuulv3.html Thanks in advance, Előd Illés irc:elodilles @ #openstack-nova

[telemetry][cloudkitty][ceilometer] Billing windows instances
by Thomas Goirand 24 Oct '22

24 Oct '22

Hi there! We're using telemetry+cloudkitty for our rating. We're happy of it, though we're having the issue that we would like to bill instances running Windows. The example given in the Cloudkitty doc shows how to bill more when an instance runs Windows. That works in theory, though in practice, Microsoft has a license model based on how many vCPU the instannce runs. So the model that the Cloudkitty documentation shows simply doesn't work with the SPLA thingy. We've looked at options. One way would of course writing a new custom pollster, but we don't like the idea: this would mean polling for all of the thousands of instances that are running in our deployments. So we would very much prefer having ceilometer running on compute node (with polling_namespaces=compute) to do the work, as this scales a way better. However, Ceilometer polls libvirt, which only has the information about the image ID, not the metadata associated with the image (like the property os_type=windows, for example). So, is there a better way than a dynamic pollster? Can this be done with ceilometer on the compute nodes? Cheers, Thomas Goirand (zigo)

Openstack cluster cannot create instances when 1 of 3 rabbitmq cluster node down
by Nguyễn Hữu Khôi 24 Oct '22

24 Oct '22

Description =========== I set up 3 controllers and 3 compute nodes. My system cannot work well when 1 rabbit node in cluster rabbitmq is down, cannot launch instances. It stucked at scheduling. Steps to reproduce =========== Openstack nodes point rabbit://node1:5672,node2:5672,node3:5672// * Reboot 1 of 3 rabbitmq node. * Create instances then it stucked at scheduling. Workaround =========== Point to rabbitmq VIP address. But We cannot share the load with this solution. Please give me some suggestions. Thank you very much. I did google and enabled system log's debug but I still cannot understand why. Nguyen Huu Khoi

[large-scale][oslo.messaging] RPC workers and db connection
by Arnaud Morin 24 Oct '22

24 Oct '22

Hey all, TLDR: How can I fine tune the number of DB connection on OpenStack services? Long story, with some inline questions: I am trying to figure out the maximum number of db connection we should allow on our db cluster. For this short speech, I will use neutron RPC as example service, but I think nova is acting similar. So, to do so, I identified few parameters that I can tweak: rpc_workers [1] max_pool_size [2] max_overflow [3] executor_thread_pool_size [4] rpc_worker default is half CPU threads available (result of nproc) max_pool_size default is 5 max_overflow default is 50 executor_thread_pool_size is 64 Now imagine I have a server with 40 cores, So rpc_worker will be 20. Each worker will have a DB pool with 5+50 connections available. Each worker will use up to 64 "green" thread. The theorical max connection that I should set on my database is then: rpc_workers*(max_pool_size+max_overflow) = 20*(5+50) = 1100 Q1: am I right here? I have the feeling that this is huge. Now, let's assume each thread is consuming 1 connection from the DB pool. Under heavy load, I am affraid that the 64 threads could exceed the number of max_pool_size+max_overflow. Also, I noticed that some green threads were consuming more than 1 connection from the pool, so I can reach the max even sooner! Another thing, I notice that I have 21 RPC workers, not 20. Is it normal?
