Autoscaling based on requests
by open infra 17 Sep '21

17 Sep '21

Hi, I have a requirement to allocate a server(VM) for each user request and make this automatic. Is it possible with Openstack autoscale? Scaling should not be done based on either cpu or memory usage as only one user is supposed to access a single VM. Regards, Danishka

[blazar] Third-party resource type plugins
by Jason Anderson 16 Sep '21

16 Sep '21

Hi all, I’ve just submitted a spec for making resources in Blazar follow a more explicit plugin architecture: https://review.opendev.org/c/openstack/blazar-specs/+/809485 The intent is to allow out-of-tree resource types, to allow deployers/operators to define their own abstractions. This could support some pretty wide-ranging implementations, like reserving bandwidth allocations on switches or perhaps access to other controlled/limited resources. I hope that this change will also enable Blazar to be adopted by a wider set of users and use cases. Please, have a look—it is currently proposed under Xena because there is not yet a Yoga spec section in blazar-specs. Cheers, /Jason

Hi to the Oslo team, Can you please release the openstackdocstheme so it can be used by the StarlingX community? This will correct the double headings issue we see now on every doc page. We've made similar historical release requests for 2.2.4 [1], 2.2.5 [2], and 2.2.7 [3] The StarlingX docs site utilizes a theme variant within the openstackdocstheme repo, but consumes packaged releases. Several recent changes merged to address Sphinx 4.x changes, and the StarlingX community would appreciate a new openstackdocstheme release to make use of them.

[neutron][networking-midonet] Propose to EOL stable/pike, stable/queens and stable/rocky branches of networking-midonet
by Lajos Katona 16 Sep '21

16 Sep '21

Hi, The older than rocky branches of networking-midonet are broken, as it seems that the last merge on stable/rocky and stable/queens happened a year ago, and even the master branch of networking-midonet is not maintained. Considering the above I propose to make stable/rocky, stable/queens, stable/pike branches End Of Life. I will wait until the end of next week for anyone who would like to maybe step up as maintainer of those branches and who would at least try to fix CI of them. If there will be no volunteers for that, I will EOL those branches in networking-midonet. Lajos Katona (lajoskatona)

Neutron
by Zeeshan Haider 16 Sep '21

16 Sep '21

**Scenario**: We are trying to develop our Virtual Network using `Open Virtual Network` or `OVN`, We need our Virtual Network Switches running firstly on the root Virtual Router, and there are some other Virtual Switches as well. I was Working on the `openvswitch` and `OVN` but a lot of things are missing for me, and there are some unlinked dots between the deployment itself and there are some problems. My Question has 3 further Parts. 1. Is it possible at all to use `Neutron` as our Network Manager without OpenStack cloud installation? 2. Is it a good approach? 3. if not then are there any cookbooks available for `OVN`, I am not talking about man-pages. Any help would be highly appreciated. P.S. I am thinking about this because OVN got merged with Neutron, and it could be one of the possibilities. **Note**: Please Don't downvote the question because I don't have that much experience with the network could be a stupid question, will remove it if you provide me the info in the comment section. I have found out that installation is possible I am quoting the answer from `https://bugs.launchpad.net/neutron` by `https://launchpad.net/~amotoki` below. "The way to install neutron is simple: to install neutron with pip (from PyPI package or the git repo), prepare a config file for neutron and start the neutron server (in case of OVN mechanism driver). Distro packages and/or various tools like Ansible playbook are just a wrapper for this. The minimum required config to enable noauth (ie without keystone) is to set auth_strategy to noauth in the config file. I don't know the detail instruction step by step to satisfy your need." Now I want to find out detailed instructions for this purpose. is this possible to get the instructions here

Hi, It's been a long time that Django 3.x is around, and therefore, it'd be nice if Horizon had some kind of support for it. Indeed, sooner or later, Django 3.x will be uploaded to Debian unstable. That day, I hope Horizon doesn't just break. So, what's the status? Is anyone is at least working on it? Cheers, Thomas Goirand (zigo)

[TripleO][RDO] Plan for TripleO packages in RDO Xena release
by Alfredo Moralejo Alonso 15 Sep '21

15 Sep '21

Hi, With OpenStack Xena GA approaching and TripleO as an independent project, we need to clarify how we will handle it in RDO Xena Release. According to the spec [1]: "TripleO would no longer be able to deploy all versions of OpenStack. One idea that was brough forth in the discussions around this topic thus far, is that we can attempt to address this by designating a range of git tags as compatible with a particular OpenStack stable branch." In practical terms: - When will this list be provided? Can I assume shortly after Xena release (around mid october)? - How will this "list of tags compatible with Xena" be provided by the TripleO project? - How may we describe the maintenance status of TripleO in RDO Xena release? We'd like to include a statement in the release notes. Best regards, Alfredo https://specs.openstack.org/openstack/tripleo-specs/specs/xena/tripleo-inde…

Need some clarification about tenant network in TripleO
by wodel youchi 15 Sep '21

15 Sep '21

Hi, It is a newbie question, but I didn't find a real answer, and I have trouble with my deployment, so some help will be appreciated. In the deployment of TripleO in network isolation, a Tenant network is created, that network (in the examples I have seen) have a VLAN-ID and a subnet. I did the same in my deployment, I created that network. My questions : - Is the Tenant network, mentioned in the deployment process, is it the first tenant network created for the admin tenant? and for new tenant I have to create a new network tenant, despite I am not seeing how I would do that? - Or is it a pipe (a conduit) used to pass the traffic of all the tenants that will be created after? Regards.

[nova] Backporting test refactors to stable/train
by Artom Lifshitz 15 Sep '21

15 Sep '21

Hey Elod and Vlad (and the ML, cc'ed) This is continuing the conversation Elod and I had on IRC. The immediate context is [1], which is a test refactor backport that in turn enables conflict-free backporting of at least two fixes. >From Red Hat's point of view, we will have to care about stable/train for *very* long time, so we'd like to do everything we can to make our lives easier, including backportings things are aren't strictly necessary (like test refactors) in order to greatly facilitate future backports, which tend to be of the "func reproducer test + actual fix" variety. Elod made the excellent point that while this approach does make backports to train much easier to both write and review, it also "postpones" all of the manual conflict resolution work onto anyone doing stable/stein backports. I went and gathered data. I looked at the last 6 months of backports in Gerrit. At the time of this writing, stable/train 72 [2] had and stable/stein had 24 [3]. Out of the latter, Vlad Gusev was the main non-Red Hat contributor. So my proposal is simple: I'm willing to help resolve conflicts in stable/stein backport for folks like Vlad, if it means making backports to stable/train easier. I'm confident that it would still mean an overall reduction in man-hours for backports, even if I become personally on the hook to deal with the fallout of backporting test refactors to stable/train. Cheers!

[tc][neutron] Use Kea insted of Dibbler for IPv6 PD
by Lajos Katona 15 Sep '21

15 Sep '21

Hi, In Neutron we have a bug (see [1]) that states Dibbler is concluded (see [2]), and the developer of Dibbler suggests using Kea (see [3]) instead. Before we start checking technical things first thing is that Kea is MPL2.0 licensed (see [4]) and not sure if we can pull that as dependency to Openstack. Kea is an ISC project so looks safe, but I am not familiar with these legal things. How can we check and be sure?

[nova] "Migrating" ComputeNode within ComputeHost / vmwareapi ComputeNode per ESXi
by Wiesel, Fabian 15 Sep '21

15 Sep '21

Hi, I am looking at adding the option for the vmwareapi driver to expose the individual ESXi hosts. A compute-host would represent a cluster in vsphere, and each ESXi-host within a cluster would be a ComputeNode. The main question here is, how to handle a hypervisor initiated change of the compute-node and if the community is open to extending the compute-driver interface for such a use-case. The secondary one is, if there is interest in having the upstream vmwareapi driver getting this functionality. * What are we trying to solve by that? Our users are asking for that feature, because they want to know, if a payload of two VMs runs on the same physical host, as the performance characteristics are quite different. We also gain there from an operational and code perspective: - Nova would become aware of the actual resources per ESXi host instead of the aggregated ones. - Resources could also be more faithfully represented in the resource-tree (e.g., shared storage as an aggregate). - Capabilities, (cpu-flags, architecture,… ), Numa topology, and even small things like up-time can be faithfully reflected on a per-host basis. - The internal scheduling decisions in the driver for ephemeral storage and compute (for live-migration) can be handled by standard placement & nova scheduling. * Why do we need to change the driver interface? Main problem here is that VSphere might migrate a VM between two ESXi-hosts for various reasons. So, the driver would need a way to communicate such a change somehow. But even if we disable all kind of migrations on VMware side, we still need a way to migrate the VMs from the single compute-node for the whole cluster to the compute nodes for each individual ESXi-hosts. * Proposed Driver API Change The Compute-Manager is currently periodically polling the driver with ComputeDriver.get_info(self, instance, use_cache) which returns an InstanceInfo, which is essentially only the power-state. Adding two new optional fields to InstanceInfo could allow the driver to inform the manager about - the current compute-node - the compute-node the VM is migrated to This allows the Compute-Manager to take care of updating the node field and the resource-allocations accordingly. Additionally, we can notify the manager over Instance lifecycle events, allowing for a faster reflection of a compute-node change. The lifecycle events could be - EVENT_LIFECYCLE_COMPUTE_NODE_MIGRATION_STARTED - EVENT_LIFECYCLE_COMPUTE_NODE_MIGRATION_COMPLETED Or one could generalize the current life-migration events to include also such compute-node changes. I am looking forward for your feedback. Cheers, Fabian

[puppet] Propose retiring puppet-freezer
by Takashi Kajinami 14 Sep '21

Hello, Today I looked into the current code of puppet-freezer and noticed this module is still very incomplete. Most of its implementations are inherited from the cookiecutter template, and the module doesn't support fundamental resources like packages, services and so on. Because we haven't seen any interest in fixing that feature gap for a long time, I'll propose retiring the module during this cycle. Please let me know if you have any concerns. If I don't hear any objections I'll submit a series of patches to retire the module. Thank you, Takashi Kajinami

MTU configuration for instances
by shubjero 14 Sep '21

14 Sep '21

Hey Openstackers, I am trying to determine how to configure/manipulate an OpenStack instances MTU configuration upon deployment/creation. I know that in neutron.conf you can set the 'global_physnet_mtu = value' and 'path_mtu = value' in ml2_conf.ini. In our case we are setting these to 9000 as the physical interfaces of our control plane and compute nodes are all using 9000 mtu however the bonded interfaces for our various networks are 8900. With this mtu configured, we've noticed that our OpenStack neutron networks within a tenancy are auto-selecting a mtu of 8958 as from what I've read it will take the 9000 mtu and minus the approriate overhead to pass the underlying physical network properly but I think because our bonded interfaces are 8900 this has started to introduce some problems in instances with operating systems that hard code the MTU from Neutron networks. When an instance gets deployed it may (Ubuntu 20.04) or may not (Ubuntu 18.04) retrieve the network mtu from neutron metadata service and builds it in to the netplan configuration as provided below.

[TripleO] Reviving the TripleO review priorities etherpad
by James Slagle 13 Sep '21

13 Sep '21

I'd like to see about helping to focus our review priorities by reviving the tripleo-review-priorities etherpad: https://etherpad.opendev.org/p/tripleo-review-priorities I deleted all the old cruft, and created some new high level topics. There are likely others as well. I'll start by filling in some links to what I think the highest priority items are, but I could use help to create an accurate list of where the core team should focus. I'd like to get some feedback on the approach in the #tripleo meeting tomorrow as well. Let me know any thoughts. -- -- James Slagle --

[designate][interop] test_create_all_recordset_types ddt issue
by Martin Kopec 13 Sep '21

13 Sep '21

Hi designate team, I'm reaching out because we have encountered a problem with one of the tests [1]. We track the following name [2]: designate_tempest_plugin.tests.api.v2.test_recordset.RecordsetsTest.test_create_all_recordset_types That test name is actually incorrect due to the ddt and the real name of the test is created dynamically based on the test data passed via ddt. We have a consistency check which is supposed to verify that the test names tracked in our guidelines match the ones in Tempest/tempest plugins, however, there was a bug - we are fixing that by [3]. The question is, should interop track all the permutations of the test? See [4]. [1] https://opendev.org/openstack/designate-tempest-plugin/src/commit/da27a70ae… [2] https://opendev.org/osf/interop/src/commit/d8eac71fa507c68e9c1f83a19dd77af8… [3] https://review.opendev.org/c/osf/interop/+/806598 [4] https://review.opendev.org/c/osf/interop/+/807586 Thank you, -- Martin Kopec Senior Software Quality Engineer Red Hat EMEA

Instances cannot ping each other and cannot ping virtual-router
by wodel youchi 13 Sep '21

13 Sep '21

Hi, I deployed OpenStack Train using TripleO using this tutorial : https://kdjlab.com/deploying-rdo-in-a-cohesive-manner/ and the documentation of TripleO. I deployed it with DVR. In my deployment I am using virtual machines with nested-kvm. The deployment went well, I am using network isolation like this : - nic1 : provisioning - nic2 and nic3 (bond0) storage and storage mgmt networks, each one in it's VLAN - nic3 and nic5 (bond1) tenant, api and *external* (10.0.2.0/24 VLAN2100) networks, each one in it's VLAN In my physical host (the bare metal KVM) I created a bridge which handles the provisioning, tenant, api and external networks. I created a private tenant network (172.16.100.0/24). openstack network create private neutron subnet-create private 172.16.100.0/24 --name private-sub --dns-nameserver 172.16.0.252 I created a public network and I attached it to the external network using the same VLAN tag (10.0.2.0/24 VLAN 2100, pool: 10.0.2.100-10.0.2.120) : *openstack network create --provider-network-type vlan --provider-physical-network datacentre --provider-segment 2100 --external public* neutron subnet-create public 10.0.2.0/24 --name public-sub --disable-dhcp --allocation-pool=start=10.0.2.100,end=10.0.2.120 --gateway=10.0.2.1 --dns-nameserver 172.16.0.252 I created a vrouter, one port in the public network and the other in the private network. I created two cirrus instances, each one got it's ip address from the private network. I found : cirrus-1 : 172.16.100.81 cirrus-2 : 172.16.100.103 vrouter : 172.16.100.1 private : 10.0.2.101 external neutron:dhcp : 172.16.100.2 The problems : - The instances cannot ping each other. - The instances cannot ping the vrouter. - I cannot ping the public vrouter interface. But both instances can ping neutron:dhcp Could someone help me dig into this. Thanks in advance, Regards.

Openstack nova live migration pain
by hai wu 13 Sep '21

13 Sep '21

This is Openstack train release. Nova live migration is extremely painful to deal with. Everytime we complete a live migration, nova-compute service on the source host would still be up and runnning, but it would always fail to further increment the report_count database field in nova database, host heartbeat purpose, thus controller would think the hypervisor host failed via its is_up() function checking on report_count and updated_at fields iirc. So we end up having to manually migrate one vm at a time, then restart service, then manually migrate the next vm .. Any ideas? I already tried setting debug=True for nova.conf even for database tracing, but thus far I could not find any obvious error message. Each time the live migration (no shared storage) would succeed, but each time we will have to restart nova-compute service. This is so bad .. Any suggestions on this would be highly appreciated. Thanks, Hai

[kolla][operators] Kolla Ansible will switch to use Quay.io by default (instead of Docker Hub)
by Radosław Piliszek 13 Sep '21

13 Sep '21

Dear Kolla Operators, This is a heads-up message that Kolla Ansible will switch to using Quay.io instead of Docker Hub by default. [1] This was agreed at the last meeting unless we find obstacles not to do it. But it seems it's even a better option for our users from China. [2] Therefore the patch [1] has been proposed and will likely be merged and probably backported to stable branches too. The main reasoning behind this change is that users suffer from Docker Hub's limits. [3] You may have noticed we started (a long time ago) publishing weekly, instead of daily, to Docker Hub to mitigate the issue to some extent. However, we had to switch our CI to Quay.io anyway to really be able to work on the project rather than pray for luck with Docker Hub. Quay.io has been great for us in general so we decided to make the same switch for users. Oh, and, by the way, we publish to Quay.io daily. ;-) If you use your own, local registry, then you are most likely unaffected but make sure you set both `kolla_registry` AND `kolla_namespace` as we have to override both. Finally, kind reminder that operators of multinode and production clusters are strongly advised to set up their own, local registries. The docs show a simple minimal example of that. [4] (use option 1 from the current page as possibility of option 2 will be gone with the switch to quay.io). Thank you for reading up to this point! [1] https://review.opendev.org/c/openstack/kolla-ansible/+/808486 [2] http://lists.openstack.org/pipermail/openstack-discuss/2021-September/02481… [3] https://bugs.launchpad.net/kolla-ansible/+bug/1942134 [4] https://docs.openstack.org/kolla-ansible/wallaby/user/multinode.html#deploy… -yoctozepto

goodbye openstack, welcome ansible
by Sorin Sbarnea 13 Sep '21

13 Sep '21

Today was my last day as a part of the OpenStack team at Red Hat. After almost 5 years, I've decided to use the opportunity to join the newly created Ansible DevTools team, a team that will improve and maintain development tools such as ansible-lint, molecule and the more recent Ansible extension for VS Code. If you are interested in finding out more, make sure to attend the next Ansible Contributor Summit <https://github.com/ansible/community/wiki/Contributor-Summit> which is happening at the end of this month. To those who will be missing me, don't worry I will not be far away. Cheers! Sorin Sbarnea

[horizon][dev] Multiple Login Sessions Enhancement Proposal
by Soares Sarto, Ricardo 10 Sep '21

10 Sep '21

Hi, Based on a new feature request about Horizon's login session, we would like to know if you're open to considering the improvement described below. If that is the case, we can submit a spec and upstream that implementation when the feature is done. Currently, a specific user is able to create multiple login sessions in Horizon, allowing him to log in to Horizon from multiple browsers/devices at the same time. The proposal is to have a parameterized solution and have a configuration to control how Horizon's login sessions are handled, the configuration options would be as below: 1 - Default option, allow the user to create multiple login sessions - this is the current behavior; 2 - Block subsequent login attempts if the user already has an active session; 3 - Invalidate the active session (if there is one) when the user creates a new one. Option number 2 obligates the user to log out of the system before opening a new one, on the other hand, in option number 3, the Horizon application is in charge of invalidating any previous active session and keeping only the latest one. This solution targets only Horizon login sessions, not affecting other kinds of sessions (e.g.: CLI).

[devstack][openstack-qa] DevStack on VirtualBox with Host-only Adapter
by os-user157 10 Sep '21

10 Sep '21

Hi all, I'm trying to deploy DevStack inside an Ubuntu Server 20.04.3 LTS virtual machine inside VirtualBox, but I'm struggling a lot, I got a lot of different errors. My use case: I want to test Zuul and DevStack, so I'll create a virtual machine for DevStack and one for Zuul, both on VirtualBox. I'm using a Host-only adapter with CIDR 192.168.200.0/24, and I need DevStack to be accessible on this network, and to use this network as the floating range for giving floating IP addresses to instances inside DevStack, so that Zuul can also access them. My local.conf: https://paste.openstack.org/show/809182/ Screenshots of the network configuration of my VirtualBox VM: First adapter, NAT (used for internet connectivity): https://i.imgur.com/C7XTiLJ.png Second adapter, host-only, used for communication with my Windows host and other VMs in the same network: https://i.imgur.com/Qeciuqx.png DevStack is erroring with the arping command on lib/neutron-legacy, arping gets 0 responses and exits the script with exit code 1 Does anyone have experience in dpeloying DevStack inside VirtualBox in such manner? I really need some help with this, if anyone could give me some ideas of waht could be wrong, it'd very much appreciated! Thanks.

[release] Release countdown for week R-3, Sep 13 - Sep 17
by Herve Beraud 10 Sep '21

10 Sep '21

Development Focus ----------------- The Release Candidate (RC) deadline is next Thursday, September 16. Work should be focused on fixing any release-critical bugs. General Information ------------------- All deliverables released under a cycle-with-rc model should have a first release candidate by the end of the week, from which a stable/xena branch will be cut. This branch will track the Xena release. Once stable/xena has been created, the master branch will be ready to switch to Yoga development. While the master branch will no longer be feature-frozen, please prioritize any work necessary for completing Xena plans. Release-critical bugfixes will need to be merged in the master branch first, then backported to the stable/xena branch before a new release candidate can be proposed. Actions ------- Early in the week, the release team will be proposing RC1 patches for all cycle-with-rc projects, using the latest commit from the master branch. If your team is ready to go for cutting RC1, please let us know by leaving a +1 on these patches. If there are still a few more patches needed before RC1, you can -1 the patch and update it later in the week with the new commit hash you would like to use. Remember, stable/xena branches will be created with this, so you will want to make sure you have what you need included to avoid needing to backport changes from the master branch (which will technically then be Yoga) to this stable branch for any additional RCs before the final release. The release team will also be proposing releases for any deliverable following a cycle-with-intermediary model that has not produced any Xena release so far. Finally, now is a good time to finalize release highlights. Release highlights help shape the messaging around the release and make sure that your work is properly represented. Upcoming Deadlines & Dates -------------------------- RC1 deadline: September 16 (R-3 week) Final RC deadline: September 30 (R-1 week) Final Xena release: October 6 -- Hervé Beraud Senior Software Engineer at Red Hat irc: hberaud https://github.com/4383/ https://twitter.com/4383hberaud
