Hi, Election details: https://governance.openstack.org/election/ The nomination period officially begins Feb 05, 2025 23:45 UTC. Please read the stipulations and timelines for candidates and electorate contained in these governance documents[1][2][3]. Due to circumstances of timing, PTL and TC elections for the coming cycle will run concurrently; deadlines for their nomination and voting activities are synchronized but will still use separate ballots. Please note, if only one candidate is nominated as PTL for a project team during the PTL nomination period, that candidate will win by acclaim, and there will be no poll. There will only be a poll if there is more than one candidate stepping forward for a project team's PTL position. Similarly, there will only be a TC poll if there are more than 5 candidates stepping forward the available TC positions. All members of the community are encouraged to confirm their email address as described at: https://governance.openstack.org/election/#electorate There will be further announcements posted to the mailing list as action is required from the electorate or candidates. This email is for information purposes only. If you have any questions which you feel affect others please reply to this email thread.

[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. Best regards, Akash Talebailkar Palc Networks akashmadan.t(a)palcnetworks.com +91 9035376555

[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.

I do not want to build special image only because of that single config file. My question is, how to make kolla-ansible to copy/add /etc/multipath.conf file into nova_compute service? Is there any mechanism for that? Thanks. Kamil Madac

[nova][neutron][ops] disabling the heal instance info cache periodic
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
