Skip upgrades
by engineer2024 29 Jan '25

29 Jan '25

Is there a way to upgrade openstack older versions like ussuri , victoria, by migrating just the nova, neutron dbs, schema to the latest version by skipping one level at once and then install the latest venvs against the latest migrated galera dbs. On the compute nodes, if we preserve just the var lib nova instances and on top of it reinstall the compute and neutron agents, will it work ? I am asking becos, I don't know what r the dependencies among the major nova versions. Are the db schema and data, the only diffs from one version to another, or is there any thing else ?

[rabbitmq] Need help about RabbitMQ quorum HA mode
by İzzettin Erdem 29 Jan '25

29 Jan '25

Hi, In kolla-ansible yoga environment, rabbitmq queues are set to quorum by default instead of classical mirroring, as it seems they are not replicated (per queue has +0 quorum). We tried to find a solution to handle it in configs, but we couldn't find it and we set queues to be replicated by using CLI commands (rabbitmq-queues grow). Now, my questions are: 1- Why do all rabbitmq queues come as non-replicated by default? 2- How can we set HA mode to quorum queues?

Does nova support flavors where vcpus of a single flavor can be in mixed modes where some of them are pinned and the rest dedicated ? Say, a flavor has 5 vcpus, I want 2 of them to be of dedicated type and the remaining 3 vcpus to be shared

[neutron][upgrades] IPv6 Prefix Delegation 'dibbler' driver removal
by Brian Haley 28 Jan '25

28 Jan '25

Hi again Stackers, In 2023, during the Bobcat cycle, the Neutron team changed the IPv6 Prefix Delegation (IPv6 PD) 'dibbler' driver to be an experimental feature [0]. The reason was due to it (dibbler) becoming unmaintained/retired upstream, as well as the low level of testing support we had in Neutron for the feature. So what does this mean? We (the neutron cores) have come to the conclusion that it is time to take the next step and remove the driver from the tree [1]. The framework to support IPv6 PD is *not* being removed, but as this is the only in-tree driver the functionality will no longer be available to end-users. We plan on doing this in the current Epoxy cycle. We realize that there may be deployments using IPv6 PD, although we have not to my knowledge ever received a bug against it, so we think any usage is very small. If there is desire to add an in-tree driver back to the code base, there is an open OVN-related bug for that at [2], we have just not had the interest from downstream customers to warrant the investment in this area. Thanks for reading, -Brian, Neutron PTL [0] https://review.opendev.org/c/openstack/neutron/+/879030 [1] https://review.opendev.org/c/openstack/neutron/+/934283 [2] https://bugs.launchpad.net/neutron/+bug/1895972

[Nova] Nova-compute service flapping on Antelope
by Jakub Darmach 28 Jan '25

28 Jan '25

Hello, Recently I encountered an interesting issue - nova-compute service started to temporarily lose Rabbit connectivity to regain it after a few seconds on Antelope. The issue was replicated on the test environment, without specific steps to replicate though - it just starts to happen after some time. I pasted a log example in the bug I opened [1]. First we can see rabbit logging closing AMQP connection, followed by nova-compute reporting rabbit server being unreachable, with next message being successful reconnection. Restarting nova-compute services helps temporarily, the issue starts to manifest after a few days. Initially disconnects once every few hours, each time in shorter intervals, to the point it happens every minute or so. Did anyone encounter something similar?

[administrivia] Bounce processing disabled for now
by Jeremy Stanley 28 Jan '25

28 Jan '25

Due to repeated challenges with random messages being rejected by subscribers' mail providers (from DMARC invalidations, lines too long to be forwarded, content misidentified as spam, et cetera), the time required for list administrators to manage the resulting extra work is greater than the benefit we get from Mailman being able to figure out when subscriber addresses become defunct. As such, I've disabled the "bounce processing" feature for the time being, until we can work out solutions to make it less of a burden on our list admins and less confusing/failure prone for the list subscribers. If we do decide to give it another try at some point in the future, after some of the current challenges with it get ironed out, I'll let the list know. -- Jeremy Stanley

[nova] Performance Issues with OpenStack Server List on os-compute-api-version 2.96
by 黒羽正徳 [Kuroha Masanori] 28 Jan '25

28 Jan '25

Hello, We have recently encountered a situation where the response time for the openstack server list command is significantly slower when specifying os-compute-api-version 2.96 for certain projects. In comparison with version 2.95, some projects experience a response time that is 2-3 times longer, while other projects show little to no difference. We understand that in version 2.96, there was a change to obtain the availability zone from the request_spec [1]. However, upon checking the instance records in request_spec for the projects, we have not identified any differences that would account for this slow response behavior. Additionally, we have observed that when certain ERROR VM is present, the response time for the server list can become considerably slower for specific projects. In one case, we resolved the slow response issue by deleting instances that did not have corresponding fault records in the database. However, the exact reason why this action resolved the issue remains unclear. If anyone has more detailed information or potential solutions regarding these issues, or if you have encountered similar situations, we would greatly appreciate your insights.

[tc][all] OpenStack Technical Committee Weekly Summary and Meeting Agenda (2025.1/R-9)
by Goutham Pacha Ravi 27 Jan '25

27 Jan '25

Hello Stackers, We're 9 weeks away from OpenStack's 2025.1 coordinated "Epoxy" release [1]. These weeks leading up to feature freeze (R-5/Feb 24-28) will be about "getting things done" for project teams. As Slawek Kaplonski (slaweq) wrote to you [2], we'll be kicking off combined elections for Project Team Leads for the 2025.2 "Flamingo" release cycle and five seats on the OpenStack Technical Committee next week. In light of this, please confirm your eligibility to vote in these elections by navigating to the CIVS website and entering your Gerrit email address: https://civs1.civs.us/cgi-bin/opt_in.pl In each of the past three elections, we've had roughly a fifth of eligible voters cast their votes. It would make a great difference to our community if we could improve this statistic with your cooperation! In the past week, the OpenStack Technical Committee approved a resolution to welcome the "Freezer" (Disaster-Recovery-as-a-Service) project back into the fold of "active" projects [3]. I'd like to extend a shout-out to Dmitriy Rabotyagov (noonedeadpunk) and Álvaro Soto (khyr0n) for their work to revive the project team. The team is looking to pursue the release of several project deliverables during this release. === Weekly Meeting === The TC weekly IRC meeting on 2025-01-21 [4] was well attended. We were in "getting things done" mode too, as much of the meeting followed up on action items from past meetings. We discussed getting more active review participation for changes to the "openstackdocstheme" repository by working with the Oslo team. We also deliberated on election nomination windows. We are in favor of early nominations from folks who are unable to self-nominate due to holidays or other personal reasons to be away from their computers during the nomination window. However, there were concerns expressed that the election officials may be burdened by the work necessary to shepherd such nominations. Early nominations would fail several CI checks, require re-checks, and potentially create some confusion. We'll attempt to watch this closely for the next election cycle and recalibrate. Our goal is to avoid leaderless projects due to holiday cycles during elections. The TC also discussed the next steps for the newly active Freezer project to release artifacts during the current release cycle. The next meeting of the OpenStack TC is today, 2025-01-28, at 1800 UTC in the #openstack-tc IRC channel on OFTC. Please find the meeting's agenda on the meeting wiki [5]. I hope you'll be able to join us. === Governance Proposals === ==== Merged ==== - Retire Freezer DR | https://review.opendev.org/c/openstack/governance/+/938183 - Remove Freezer from inactive state | https://review.opendev.org/c/openstack/governance/+/938938 ==== Open for Review ==== - Retire qdrouterd role | https://review.opendev.org/c/openstack/governance/+/938193 - Reset the DPL model for Oslo project | https://review.opendev.org/c/openstack/governance/+/939485 - Reset the DPL model for Release project | https://review.opendev.org/c/openstack/governance/+/939486 - Add devstack-plugin-prometheus repo to Quality Assurance repos | https://review.opendev.org/c/openstack/governance/+/939953 - Reset the DPL model for Watcher project | https://review.opendev.org/c/openstack/governance/+/939488 - Add Watcher project update liaison | https://review.opendev.org/c/openstack/governance/+/940168 - Adopt DPL model for Watcher 2025.2 | https://review.opendev.org/c/openstack/governance/+/940167 - Define 2025 upstream investment opportunities | https://review.opendev.org/c/openstack/governance/+/939507 - Add resolution for late Freezer release | https://review.opendev.org/c/openstack/governance/+/939792 - Deprecate ironic-lib | https://review.opendev.org/c/openstack/governance/+/939278 - Resolve to adhere to non-biased language | https://review.opendev.org/c/openstack/governance/+/934907 === Upcoming Events === - 2025-01-28: OpenInfra Board Monthly Meeting: https://board.openinfra.org/ - 2025-02-01: FOSDEM 2025 (https://fosdem.org/2025/) OpenStack's 15th Birthday Celebration - 2025-02-05: Nominations open for 2025.2 TC/PTL Elections: https://governance.openstack.org/election/ - 2025-02-28: 2025.1 ("Epoxy") Feature Freeze and release milestone 3 [1] - 2025-03-06: SCALE 2025 + OpenInfra Days NA (https://www.socallinuxexpo.org/scale/22x) Thank you very much for reading!

[openstack-helm] Use Loci images by default
by Vladimir Kozhukalov 26 Jan '25

26 Jan '25

Hi, This is to announce multiple things: 1) OpenStack/Loci (a project for building OpenStack images) is currently equipped with periodic jobs that are run nightly. These jobs build images for 3 most recent OpenStack releases: - 2023.2 Bobcat - 2024.1 Caracal - 2024.2 Dalmatian Images are published to these two destinations: - docker.io/loci/* (which is known for its strict request rate limits) - quay.io/airshipit/* (which is much more tolerant to the number of requests) Images are tested before publishing with two basic deployment configurations: - compute-kit (Deploy minimal set of OpenStack components to run VMs) - cinder (Deploy Cinder with Ceph backend) 2) By default we are going to use Loci images published to the Quay registry [1]. All test jobs will be run with these images and this is also a recommendation for users to consume images from quay to mitigate possible rate limit issues. 3) OpenStack/OpenStack-Helm-Images project will build only non-OpenStack images. Primarily the motivation is to deduplicate the code base. Consequently, OpenStack images published nightly to docker.io/openstackhelm/* will not be updated after 2024.2.

Guidance Required for OVN-BGP-Agent Configuration with EVPN Mode
by AkashMadan Talebailkar 26 Jan '25

26 Jan '25

Dear Community, I hope this email finds you well. I came across this insightful discussion on the OpenStack forum regarding the OVN-BGP-Agent Discussio<https://lists.openstack.org/pipermail/openstack-discuss/2022-August/030080.…>n. We are doing research on openstack capability and would greatly appreciate your guidance. We are utilizing the OVN mechanism driver along with the OVN-BGP-Agent<https://github.com/openstack/ovn-bgp-agent/tree/master> in EVPN mode. Our objective is to establish BGP-EVPN between our leaf switch and the OpenStack controller. The OVN-BGP-Agent should advertise the IP and MAC addresses of VMs to its BGP peers. Please find attached the following details for your reference: bgp-agent.conf Agent configuration OVN_DB configuration Result We installed the OVN-BGP-Agent and FRR on the controller. Below are the steps we followed: Network Setup: Created a tenant network (NET) with a subnet of 121.168.0.0/24. Created a provider network (EXNET) with a subnet of 192.27.5.0/24. Router Configuration: Set up a router (newrouter) with an external network (EXNET) and unchecked SNAT. Added the NET interface to the router. OVN Database Configuration: Configured the OVN Northbound DB (detailed in the attachment). VM Creation: Deployed a VM in NET with the VM's IP 121.168.0.202 PFA for the agent configuration and FRR configuration done once agent VM has been created. Despite following the steps above, the VM IP is not visible in FRR, PFA for the result. Consequently, we are unable to advertise its route via BGP-EVPN. We kindly request your guidance to identify any potential misconfigurations or missing steps. Thank you for your time and support.

[kolla-ansible] Multipath unsuccesfull in nova
by Kamil Madac 24 Jan '25

24 Jan '25

Hello, I have a openstack deployed with kolla-ansible 2024.2. I'm trying to configure cinder and nova to use multipath when attaching volumes from the Hitachi SAN array. Without multipathing everything works good. When I enabled multipath in kolla-ansible (enable_multipathd: "yes"), deployment is without errors, volume can be created, but attachment of volume ends up with error in nova_compute container: ... 2025-01-22 12:16:02.962 2 ERROR nova.virt.block_device [instance: 714bd6f8-49e5-406f-b608-b7aaded2e728] raise exc_type(*result[2]) 2025-01-22 12:16:02.962 2 ERROR nova.virt.block_device [instance: 714bd6f8-49e5-406f-b608-b7aaded2e728] oslo_concurrency.processutils.ProcessExecutionError: Unexpected error while running command. 2025-01-22 12:16:02.962 2 ERROR nova.virt.block_device [instance: 714bd6f8-49e5-406f-b608-b7aaded2e728] Command: multipath -C dm-0 2025-01-22 12:16:02.962 2 ERROR nova.virt.block_device [instance: 714bd6f8-49e5-406f-b608-b7aaded2e728] Exit code: 1 2025-01-22 12:16:02.962 2 ERROR nova.virt.block_device [instance: 714bd6f8-49e5-406f-b608-b7aaded2e728] Stdout: '' 2025-01-22 12:16:02.962 2 ERROR nova.virt.block_device [instance: 714bd6f8-49e5-406f-b608-b7aaded2e728] Stderr: '3601817.750747 | /etc/multipath.conf does not exist, blacklisting all devices.\n3601817.750753 | You can run "/sbin/mpathconf --enable" to create\n3601817.750754 | /etc/multipath.conf.

Is there any mechanism for that? Thanks. Kamil Madac

by Sean Mooney 23 Jan '25

23 Jan '25

hi folks o/ This is a short PSA and request for comments The nova and neutron teams have discussed the existence and importantly the default behavior of nova's "heal instance info cache periodic" on an off for the better part of the last 4+ years but we never had time to take any action on it until now. Context for those who are not aware of it, nova has an instance info cache which we use to cache networking information such as ip address related to ports associated with an instance. This was introduced in the Essex release when nova networks was being replaced with quantum/neutron. Its rater fitting but over due that in the Epoxy release we are now turning this off. for more context i have captured some of the important point in the release note of the proposed change https://review.opendev.org/c/openstack/nova/+/939476/2/releasenotes/notes/d… But ill provide a TL;DR here. By default, as of essex, [compute]heal_instance_info_cache_interval defaulted to 60. it has been possible to disable this by setting the value to <=0 (recommended to use -1 by convention). when the periodic is enabled, every nova compute agent loop over the instance on the current host, retrieves all there ports form neutron and fully rebuilds the cache(as of stein). on a small cloud (less then 50 computes) this has minimal impact on the performance of the neutron server, on moderate to large clouds this creates 10s of MB of constant db read load. This has several side-effects: - first it creates unnecessary load on the neutron api and neutron db/network backend in creasing latency and reducing overall performance. - second, it create unnecessary load on rabbitmq as each compute service need to do an RPC to update the info cache(every 60 seconds). - third both of the first two waste power doing extra work that is not needed. - finally as of Icehouse this periodic has been optional because we added the os-server-external-events api so that neutron can tell nova if there has been a change to refresh the cache as needed. With that in mind hte nova team is proposing that we disable this going forward, for this release i have not deprecated the periodic so operators can re-enable it if they find its required for any reason. in the 2026.1 release we will likely revisit this based on operator feedback/bug reports. In this weeks team meeting we agree to wait 2 more weeks to get feedback from OPS if they had any concerns with this change hence this email. If anyone knows of a reason why we should not proceed with this default change feel free to let us know via this email thread or the gerrit review https://review.opendev.org/c/openstack/nova/+/939476 regards sean
