[cinder][ceph rbd driver] create volume in EC pool by download, but not clone
by Tony Liu 13 Dec '24

13 Dec '24

Hi, With Antelope, when create a volume in EC pool from image, Cinder downloads the image and upload it to volume, instead of cloning it as create volume in replicated pool. May I know the intention behind it? Why not clone it? Also, in case the intention is to remove dependency, clone and flatten works better. Thanks! Tony

[nova][tc] Removing md5 in password injection
by Thomas Goirand 12 Dec '24

12 Dec '24

Hi, I didn't feel it would be controversial, though it seems removing md5 password injection is still up to debate: https://review.opendev.org/c/openstack/nova/+/935512 Of course, I'd like the TC to agree with me that injecting md5-hashed passwords is, in 2024, to be considered a security problem that should be fixed (and backported) ASAP. BTW, IMO this patch could be using the new feature from oslo_utils.secretutils that Takashi managed to get in: https://review.opendev.org/c/openstack/oslo.utils/+/931899 https://review.opendev.org/c/openstack/oslo.utils/+/935525 These, IMO, should also be backported to earlier oslo.utils releases, so we can fix earlier OpenStack releases in a nicer way. Cheers, Thomas Goirand (zigo)

[cinder][ceph rbd] change volume type
by Tony Liu 12 Dec '24

12 Dec '24

Hi, With Antelope, old volume type is on replicated pool and new volume type is on EC pool. Change volume type doesn't work, volume type remains and no error returns. Is such change supported? I also tried change volume type from one replicated pool to another replicated pool. Doesn't work either. Am I missing anything? Thanks! Tony

[Openstack-ansible][Rabbitmq] Rabbitmq role is installing latest version of rabbitmq even after setting package version in variable file
by Danish Khan 12 Dec '24

12 Dec '24

Dear All, I have upgraded few of my openstack clusters from Ussuri to Wallaby successfully. But it seems rabbitmq repo is changed and now rabbitmq is getting its packages from: https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-server/deb/ubuntu Everything was working fine until I face below issue while running rabbitmq playbook: TASK [rabbitmq_server : Apply rabbitmq policies] ******************************************************************************************************* failed: [rabbit_mq_container] (item={'name': 'HA', 'pattern': '^(?!(amq\\.)|(.*_fanout_)|(reply_)).*', 'priority': 0, 'tags': 'ha-mode=all'}) => {"ansible_loop_var": "item", "changed": false, "cmd": "/usr/sbin/rabbitmqctl -q -n '' set_policy -p / HA '^(?!(amq\\.)|(.*_fanout_)|(reply_)).*' '{\"ha-mode\": \"all\"}' --priority 0", "item": {"name": "HA", "pattern": "^(?!(amq\\.)|(.*_fanout_)|(reply_)).*", "priority": 0, "tags": "ha-mode=all"}, "msg": "Error:\nValidation failed\n\n[{<<\"ha-mode\">>,<<\"all\">>}] are not recognised policy settings", "rc": 69, "stderr": "Error:\nValidation failed\n\n[{<<\"ha-mode\">>,<<\"all\">>}] are not recognised policy settings\n\n", "stderr_lines": ["Error:", "Validation failed", "", "[{<<\"ha-mode\">>,<<\"all\">>}] are not recognised policy settings", ""], "stdout": "", "stdout_lines": []} It seems ha-mode=all is deprecated in latest version of Rabbitmq (4.0.4). I tried to install 3.8 or some other compatible version of rabbitmq but anyway the latest version of rabbitmq is getting installed. I have updated below entries of file /etc/ansible/roles/rabbitmq_server/vars/debian.yml : _rabbitmq_package_version: "3.8.14-1" and _rabbitmq_erlang_version_spec: "{{ (rabbitmq_install_method == 'external_repo') | ternary('1:23.3.4.15-1', '1:22.*') }}" Can someone please help me with this? I guess either I need to find a away to install specific version of rabbitmq to fox rabbitmq policy issue or I need to update parameters of command while applying policy. Regards, Danish Khan

Nothing else comes to mind. Basically it's the desire to avoid ToFU style finger-crossing that the SSH host key you get on initially connecting to a newly booted server instance is really coming from that instance and not a MitM or honeypot. It's possible in most providers to create an authenticated backchannel by abusing the console log, as I described, but that has its own challenges. I suppose there might be alternative management protocols similar to SSH which rely on asymmetric key algorithms to authenticate hosts, but I'm not personally familiar with any (none with the near ubiquity of SSH at any rate). > perhaps we can try and capture this is a spec or separate thread > and work out what an mvp would look like. there would basically be > two part, one extednign the metadata api to support recording the > host key fingerprint somewhere, and then making that discoverable > via the main api perhaps in server show. That would make sense, and it would probably also be a good idea to try to involve e.g. a cloud-init maintainer in any such design discussion, as this would need client-side integration eventually anyway in whatever's going to communicate the key back to nova. > is we allowed read write access to all instance metadata we would > would not actually need to modify the main api as you can already > list metadata on an instance but im worried that could be abused > so i don't know if that is a good idea.

Agreed, I suppose the field could be given a more generic name in case certain kinds of guests wanted to store functionally similar things in it, but as I said I don't know what else that would end up being anyway. -- Jeremy Stanley

Some questions about ironic
by Johnny Hao 11 Dec '24

11 Dec '24

Hi Buddies, I am new to ironic, after some study, I have several questions about it, could anyone help to answer? Thanks a lot. 1. According to the workflow chart below, what's the communication method between nova-compute and Ironic API? HTTP API call or RPC call through mq like rabbitmq? So are the communications between Ironic Conductor and other components of Neutron, Glance and Cinder/Swift etc? 2. Where do Ironic services run (Ironic API/Conductor/Drivers and DB)? In the controller node? Or a separate node is also supported? ** -- Best regards QingFeng Hao

[nova] riscv64 emulation support
by James Page 11 Dec '24

11 Dec '24

Hi Nova Team We've had some initial support for enabling RISCV64 support in Nova in a review for sometime which I refreshed this week: https://review.opendev.org/c/openstack/nova/+/889137 Sean suggested that this really needs a blueprint and discussion at the next Nova meeting (which I can't make) so proposing discussion via ML instead: https://blueprints.launchpad.net/nova/+spec/riscv64-emulation-support I'm also going to look at the nova-emulation job to see if that can be extended to cover RISCV64 as well - there are a few nuances with dependent packages (opensbi) in Ubuntu 24.04 but I think we can come up with something workable for testing. Review and comments are appreciated. Thanks James

OpenStack metrics and logs
by Timothé Bauge 11 Dec '24

11 Dec '24

Hello Stackers, I would like to know what are you all using to monitor and supervise your Openstack clusters ? We are in the process of setting up our own private cloud based on RedHat OpenStack Platform 17.1, we choose not to go with the RedHat Service Telemetry Platform, and were strongly advise against Ceilometer and aodh. At the moment, we built our own stack based on Prometheus (with the plenty of exporters) for the metrics, Graylog + OpenSearch for the logs, and Grafana for the visualisation. For now, we are only looking to retrieve basic information in order to know if a dysfunction occurs, but the end goal might be to go as far as to be able to count the cpu/mem/disk usage per hour per vm per project, etc. So, what are you all using and how did you implement it ? Best regards, [cid:659cb34d-63ad-4c5a-94e4-734ef252c20b] Timothé BAUGÉ timothe.bauge(a)covage.com<mailto:pr%C3%A9nom.nom@covage.com> COVAGE I Wholesale B2B du Groupe Altitude

Hello everyone, As you might know, the Monasca project is not active and was marked 'inactive' since 2024.1 cycle[1]. In this cycle also, this project is leaderless[2] and no maintainer stepped up to maintain it. As discussed in the Leaderless project etherpad[2], the next step is to retire the project. I'm sending this email to propose the Monasca retirement and based on the response, I will proceed next.

Hello Everyone, As per the 2025.2 cycle testing runtime, we need to run upstream CI/CD jobs on Ubuntu Noble (24.04) [1]. For better tracking and speeding up this work, it is the community-wide goal for this cycle[2]. This is the etherpad which has the migration plan and will be used for the tracking: - https://etherpad.opendev.org/p/migrate-to-noble I have prepared the change(WIP) for base jobs migration on Noble (openstack tox jobs, devstack, and tempest) which will migrate most of the projects jobs. Tempest change[3] include dependency on openstack tox, devstack base jobs changes so testing project gate using the the tempest change will test the complete set. Refer to the etherpad for the complete migration plan/steps. * Deadline: Nov 29th 2024 (R18) is the deadline to test/fix the projects jobs and to merge the base jobs running on Noble (openstck tox, devstack, and tempest).

[tc][all] OpenStack Technical Committee Weekly Summary and Meeting Agenda (2025.1/R-16)
by Goutham Pacha Ravi 10 Dec '24

10 Dec '24

Hello Stackers, We're 16 weeks away from the 2025.1 ("Epoxy") release date (2024-04-02) [1]. OpenStack project teams are planning bug squashes and review jams in the next couple of weeks before contribution activity slows due to end-of-the-year holidays around the world. The OpenStack Technical Committee did not merge any new governance changes this week; however, a few proposals are iterating with community and TC review. === Weekly Meeting === The OpenStack Technical Committee held its monthly video conference last week, which was simultaneously recorded via text on IRC [2][3]. The discussion tracked several TC initiatives for this release cycle [4]. Most notably, the recent migration of base integration jobs to Ubuntu 24.04 LTS and Python 3.12 has caused CI jobs to break for several code repos [5]. I’d like to reiterate that project teams must resolve these issues or temporarily pin the nodeset of their test jobs to "ubuntu-jammy" to buy some time for fixes. We then checked on the status of "unmaintained" branches. The release team wanted the TC to solidify processes for two specific issues: nominating "unmaintained" liaisons and establishing guidelines for retiring these branches. The lack of such processes has resulted in the proliferation of "unmaintained" code branches across the community and failure to implement the TC resolution that created these branches [6]. The oldest unmaintained branch is "unmaintained/victoria", and it’s unclear if anyone benefits from keeping it around. Discussion on cleanup has been delayed due to uncertainty about what to do [7]. Meanwhile, branches like Yoga may still have high usage and active contributors, emphasizing the need for a clear process to decide their fate. The technical committee may consider advising the release team to eliminate branches with low usage, but this doesn’t solve the problem of finding volunteers to maintain high-usage branches. The idea is that projects can opt to maintain more branches if there is sufficient user interest and support, but there is currently no process for this, nor is it clear how to recruit volunteers. We agreed to continue this discussion at the next meeting. However, in the meantime, there were no objections to EOL-ing the Victoria, Wallaby, and Xena branches. Clark Boylan (clarkb) noted an issue with building CentOS Stream 10 images using Disk Image Builder, as they cannot boot on several clouds due to the x86_64 v3 CPU instruction set requirement. Only a few provider clouds, including OpenMetal and Rackspace Flex, meet the CPU requirements to boot CentOS 10. This limitation may affect options for regular test nodes, and project teams are advised to take notice. Until all Zuul/Nodepool cloud providers meet the CPU requirements, teams may need to adjust their testing strategies. Jeremy Stanley (fungi) reminded us that nominations for individual member representatives for the OpenInfra Foundation Board of Directors are still open [8]. Ten nominations from members are required to make it onto the ballot. The OpenStack TC's next weekly meeting is today, 2024-12-10. This will be an IRC meeting hosted on #openstack-tc at 1800 UTC. Please find the agenda on the meeting wiki [9]. I look forward to seeing you there. === Governance Proposals === ==== Open for Review ==== Add ansible-role-httpd repo to OSA-owned projects | https://review.opendev.org/c/openstack/governance/+/935694 Retire Murano/Senlin/Sahara OpenStack-Ansible roles | https://review.opendev.org/c/openstack/governance/+/935677 Rework the initial goal proposal as suggested by people | https://review.opendev.org/c/openstack/governance/+/931254 Resolve to adhere to non-biased language | https://review.opendev.org/c/openstack/governance/+/934907 Propose to select the eventlet-removal community goal | https://review.opendev.org/c/openstack/governance/+/934936 Thank you very much for reading!

Kolla-Ansible: Why is handling kolla_*_fqdn in /etc/hosts out of scope?
by Matthias Tinnemeier 09 Dec '24

09 Dec '24

Dear Community, According to the documentation (https://docs.openstack.org/kolla-ansible/2024.2/admin/advanced-configuratio…) the provisioning of kolla_*_fqdn Name Resolution via /etc/hosts must be managed outside of the scope of Kolla. The question, therefore, is why :-) Given the existence of "customize_etc_hosts", there should be at least some logic to implement this behaviour in an automatic way. Is there a particular reason why this is not being implemented via Kolla? Alternatively, would it be worth proposing a patch for this? With kind regards Matthias

a suggestion: use LDAP to manage all openstack components configuration
by Shi Wei 09 Dec '24

09 Dec '24

Hi, everyone, I have a suggestion. we can use LDAP service to mange all openstak components and nodes(including physical nodes and vm nodes).  Because ldap is easy to read and ldap can support DNS and DHCP service. if a node get ip address by DHCP server with ldap. You and get the Mac address information from the LDAP server. and if all components are communicated by domain name. all records are on the LDAP server. if the one node will change IP address, you can just modify on the ldap server.  The ldap server can easy to backup and extend. use ldap command to export as a ldf file.   you can easy to backup before update configuration. if a new component will join, you can extend the schema by .sch file.

Under what circumstances might these ports change? For example, would they differ in custom deployments or under certain OpenStack configurations?

about accelerating database initialization
by Jiatong Shen 07 Dec '24

07 Dec '24

Hello all, I am trying to find out if there are ways to accelerate the database initialization process. We are using openstack-helm for deployment victoria OpenStack cluster and internally openstack-helm uses nova-manage db sync command to bootstrap the database. It works but a little bit slower than expected. Right now, I am measuring this bootstrap command could took around 2 minutes to complete. I'd like to get some advices on accelerating the process as well as what is the reasonable time to have. Thank you very much for your insights. -- Best Regards, Jiatong Shen

Hello, As agreed during the latest IRC meeting, Kolla Yoga and Zed deliverables (Kolla, Kolla-Ansible, Kayobe) are going EOL. [1] Antelope remains as unmaintained, while Bobcat, Caracal and Dalmatian are our current stable releases. Yoga and Zed branches were unmaintained for a while, Kolla community does not have resources to support those branches actively. All changes to those branches have been abandoned.

Open Stack APIs
by darsh.mehta＠crestdata.ai 05 Dec '24

05 Dec '24

Hello, We want to create an integration with OpenStack for which we require the REST APIs to connect to OpenStack. However, OpenStack provides 2 offerings i.e. Cloud and On-Prem. We are referring to the OpenStack API documentation available over here https://docs.openstack.org/api-quick-start/api-quick-start.html#. But it does not specify anywhere whether the APIs are for cloud or on-prem. Are the APIs same for both or do we have separate documentation for each of these? Thanks in advance!

[Neutron] WSGI migration issues and eventlet requirements bump
by Rodolfo Alonso Hernandez 05 Dec '24

05 Dec '24

Hello Neutrinos: There is a patch [1] that is trying to bump the eventlet upper version. However, the tempest job is failing because of Neutron. There is a series of patches [2][3][4][5] that are trying to address the problems we are having with the migration to WSGI. I would ask you to review them soon in order to unblock the requirements patch. On top of this series there is a testing patch with several tempest jobs running. We still have some problems but they are limited. Thanks!

OSA adding compute without deploy host
by Derek O keeffe 04 Dec '24

04 Dec '24

Hi all, I have a controller and 2 compute setup that was deployed some time ago with OSA. It's been running fine since it was deployed but we now have the need for more compute and I was looking at the deploy host to add a compute host to the cluster. Unfortunately it seems the deploy host was repurposed and I have lost all the config. So two questions, 1) Is it possible to manually add a compute to the cluster (I fairly confident this is a yes) and 2) if so is there any documentation or how to that someone could point me to/share? any help would be greatly appreciated. Regards,Derek

[kolla-ansible][neutron][openvswitch]
by Adam Tomas 04 Dec '24

04 Dec '24

Hi everyone. I have strange problem with neutron ml2 plugin. I have a little strange setup: controllers in networkA/subnetA computesA in networkA/subnetA computesB in networkB/subnetB (separate L2, controllers can be connected via routing) Because computesB are on different LAN I had to put on two computes in that lan neutron-dhcp-agents and add them to networks served for instances in locationB. In addition aggregates are created so, that if an instance has network from locationB then it has to start on computes in locationB. computes and controllers have one flat network (vlan 21) ans three vlan networks (221, 51 and 251),, vlans 21 and 221 are in locationA, 51 and 251 in locationB, the ml2_plugin is configured like below: [ml2_type_vlan] network_vlan_ranges = physnet1:221:221,physnet2:51:51,physnet3:251:251 bond0 is the neutron_external_interface and has vlan 21 as native and 221,51 and 251 as tagged vlans. Openstack networks are mapped to corresponding physnets. dhcp_agents in location A are working without any problems, vm's are started without any problem in vlans 21 and 221 with addresses from all subnets from networks in these vlans. In location B when I add dhcp_agent the port is doen (namespaces qdhcpxxxxxxxxx are created on computesB and are replying to their own address, but not the gateway or any other address), port status of dhcp_agent is DOWN, and in logs I have: Device Port(admin_state_up=True,allowed_address_pairs=[],binding_levels=[],bindings=[PortBinding],created_at=2024-12-01T17:52:25Z,data_plane_status=None,description='',device_id='dhcpfd2f8da2-397b-5456-a75c-f9c5bbccb8b1-81b9ac42-6267-48e2-8352-0ae5c09d85fa',device_owner='network:dhcp',device_profile=<?>,dhcp_options=[],distributed_bindings=[],dns=None,fixed_ips=[IPAllocation,IPAllocation],hints=None,id=08c60b9d-ea8f-4a2d-a3b7-5f787d15f45d,mac_address=fa:16:3e:37:27:0c,name='',network_id=81b9ac42-6267-48e2-8352-0ae5c09d85fa,numa_affinity_policy=<?>,project_id='c0e2f3d69c064ae5b5596fd150d550d7',qos_network_policy_id=None,qos_policy_id=None,revision_number=2,security=PortSecurity(08c60b9d-ea8f-4a2d-a3b7-5f787d15f45d),security_group_ids=set([]),status='DOWN',updated_at=2024-12-01T17:52:25Z) is not bound.

In location B the same situation is with all ports - even if I create a port "by hand". The error message (in debug mode!) says not much - Device 08c60b9d\-ea8f\-4a2d\-a3b7\-5f787d15f45d not defined on plugin or binding failed, how can I find what is wrong? I would appreciate any help.

[masakari] failures with new version of Eventlet
by Herve Beraud 04 Dec '24

04 Dec '24

Hey Masakari maintainers, Masakari is failing with new the version of Eventlet https://review.opendev.org/c/openstack/requirements/+/933257 This job failure indicates that Masakari will surely stop working correctly once this version bump will be merged, and we need that requirements bump to support newer versions of Python in OpenStack, so... Masakari is a non-voting job, so even if this job is failing, the requirement bump will proceed, but that would be better if every project is compatible and ready to go. If you need help do not hesitate to: - join us on #openstack-eventlet-removal; - join us at our next meeting (Dec 17) https://wiki.openstack.org/wiki/Eventlet-removal#Recurring_Events. Thanks for your hard work. -- Hervé Beraud Senior Software Engineer at Red Hat irc: hberaud https://github.com/4383/

[tc][all] OpenStack Technical Committee Weekly Summary and Meeting Agenda (2025.1/R-17)
by Goutham Pacha Ravi 03 Dec '24

03 Dec '24

Hello Stackers, This week marks the 2024.2 ("Dalmatian") release trailing deadline [1]. All projects following the cycle-trailing release model [2][3] must release their 2024.2 ("Dalmatian") deliverables by December 5, 2024. No new governance changes were merged in the past week; goal champions and volunteers continued their efforts on the cross-community goals that have been committed to [4]. As Ghanshyam Mann (gmann) highlighted in this mailing list [5], nine project teams need to address CI jobs within their repositories due to the switch of base DevStack (and some tox) jobs to Ubuntu 24.04 LTS. Teams can work around the problem temporarily by pinning the nodeset used to run their failing jobs to Ubuntu 22.04 LTS while they triage and resolve these issues. The Ironic and Neutron teams recently dropped functional testing with the PostgreSQL database. As highlighted at the PTG [6], there is very little motivation within OpenStack's contributor community to support PostgreSQL as a database alternative to MySQL and its derivatives with Oslo.db. The TC has clarified this in a past resolution as well [7]. We are currently identifying places within the documentation where PostgreSQL references need to be removed and aim to address these promptly. If you rely on PostgreSQL, please voice your concerns and consider dedicating time and resources to reviving testing with this database. === Weekly Meeting === TC members met last Tuesday (2024-11-26) on OFTC's #openstack-tc channel [8]. A significant portion of the discussion focused on the state of CI. Members of the Testing and Collaboration Tools SIG highlighted that much of the gate flakiness is due to jobs encountering the new rate limits on DockerHub [9]. Alternatives that may be more suitable for CI usage within open-source communities were discussed. As a result, we encourage project teams to explore these alternatives, as many open-source communities have already done. The OpenStack TC's next weekly meeting is today (2024-12-03). It will be held simultaneously via video (Zoom) and IRC (OFTC's #openstack-tc channel) at 18:00 UTC. The agenda for this meeting, along with participation links, can be found on the wiki [10]. I hope to see you there! === Governance Proposals === ==== Open for Review ==== - Retire Murano/Senlin/Sahara OpenStack-Ansible roles: https://review.opendev.org/c/openstack/governance/+/935677 - Add ansible-role-httpd repo to OSA-owned projects: https://review.opendev.org/c/openstack/governance/+/935694 - Rework the initial goal proposal as suggested by the community: https://review.opendev.org/c/openstack/governance/+/931254 - Resolve to adhere to non-biased language: https://review.opendev.org/c/openstack/governance/+/934907 - Propose to select the eventlet-removal community goal: https://review.opendev.org/c/openstack/governance/+/934936 Thank you for reading!
