[PTL][release][stable] 2023.2 Bobcat transition to End of Life
by Elõd Illés 10 Apr '25

10 Apr '25

Hi teams, As 2025.1 Epoxy was released last week and we are in a less busy period (except the PTG :)), now is the good time to call your attention to the following: In 3 weeks 2023.2 Bobcat is planned to transition to End of Life [1] (planned date: 2025-04-30). Note that 2023.2 Bobcat is not a SLURP release, hence it is not eligible to transition to Unmaintained [2] and will move to End of Life directly and the tip of stable/2023.2 branches will be tagged with 2023.2-eol tag and stable/2023.2 branches will be deleted afterwards. To projects with cycle-with-trailing release model (Kolla, OpenStack Ansible, Puppet OpenStack): transition of your projects have an extended deadline, ~2 months after the planned EOL date (2025-04-30). I have generated the list of the current *open* and *unreleased* changes in stable/2023.2 for every repositories [3] (where there are such patches). These lists could help the teams who are planning to do a *final* release on Bobcat before deleting stable/2023.2 branches. Feel free to edit and extend these lists to track your team's progress! *NOTE*: teams, please focus on wrapping up your libraries first if there is any concern about the changes, in order to avoid broken (final!!) releases! Also please try to avoid any regression in the final stable release and do not propose any release that has only non-functional code changes.

GPU PCI passthrough woes.
by Andy Speagle 09 Apr '25

09 Apr '25

Hey Folks, I could use a little assistance getting GPU passthrough working. I had this working already for one flavor of nvidia gpu... and I've added some hosts with a much newer gpu... I've updated the pci_alias and pci_passthrough variables and those seem to be getting set properly in nova.conf passthrough_whitelist = [{"vendor_id":"10de", "product_id":"1b06"},{"vendor_id":"10de", "product_id":"26b9"}] alias = {"name": "gpu", "product_id": "1b06", "vendor_id": "10de"} alias = {"name": "gpu-l40s", "product_id": "26b9", "vendor_id": "10de"} I believe I have all of the iommu stuff configured and have the pci- stub module entries... dmesg output shows that the GPUs are being claimed by the stub module. $ openstack flavor show t1.small_gpu_l40s +----------------------------+--------------------------------------+ | Field | Value | +----------------------------+--------------------------------------+ | OS-FLV-DISABLED:disabled | False | | OS-FLV-EXT-DATA:ephemeral | 0 | | access_project_ids | None | | description | None | | disk | 0 | | id | af70c94e-0026-4a39-bc1e-dfb93b286a54 | | name | t1.small_gpu_l40s | | os-flavor-access:is_public | True | | properties | pci_passthrough:alias='gpu-l40s:1' | | ram | 2048 | | rxtx_factor | 1.0 | | swap | 0 | | vcpus | 1 | +----------------------------+--------------------------------------+ Yet... I can't seem to get an instance to run using that new flavor... keeps complaining about there not being enough hosts available.

[telemetry] Export Openstack Metrics to Prometheus
by Fernandes Figueiredo, Alex 08 Apr '25

08 Apr '25

Hello Openstack Telemetry Team, Do you know if we have a Prometheus exporter already available to export Openstack metrics stored by Gnocchi? I'm currently working on re-enabling the Openstack Telemetry services for the StarlingX Openstack (STX-O) project and we are moving in the direction of using the standard Openstack telemetry pipeline: openstack services -> ceilometer -> gnocchi -> aodh. However, to enable the integration with other systems and tools, we are looking for a way to export the Openstack metrics stored by Gnocchi to Prometheus. Thank you in advance for any help. Regards, Alex Figueiredo.

security auditing and compliance in OpenStack environments
by acc.bu.mo＠gmail.com 08 Apr '25

08 Apr '25

Hi everyone, I'm currently working on my end-of-studies project focused on security auditing and compliance in OpenStack environments. As part of this project, I'm exploring how OpenStack deployments can align with compliance frameworks, especially SecNumCloud (from the French cybersecurity agency ANSSI). However, I'm also very interested in hearing about any tools, methods, or practices used for other standards (ISO 27001, CIS, FedRAMP, etc.). I'm still new to OpenStack and cloud compliance in general, and I'm finding it challenging to identify practical tools or workflows that companies actually use to perform security audits or compliance checks in OpenStack. If you're using (or have used) any tools, scripts, checklists, middleware, SIEM integrations, etc. for auditing OpenStack security or compliance I would be incredibly grateful if you could share your experience or point me in the right direction 🙏 Thank you so much in advance! Best regards,

Debian OpenStack Epoxy packages are available
by Thomas Goirand 08 Apr '25

08 Apr '25

Hi, Just a quick mail to tell everyone that I have finished Tempest validation of OpenStack Epoxy for OpenStack Bookworm backports. Currently, 1468 tests are passing, and there's only 8 tests that I need to investigate, though looking at the logs, it doesn't seem anything important is ongoing. Also note that I have integrated all Designate tests, that are all passing ok. As always, packages are available through osbpo.debian.net unofficial backports, accessible using extrepo. Under Bookworm, simply do: apt-get install extrepo extrepo enable openstack_epoxy apt-get update I haven't started validation under Debian 13 (aka: Trixie). I'm am currently working on it. It's going to be a little bit more difficult as Trixie runs RabbitMQ 4.0.5, which doesn't support HA queues anymore, so I need to switch to quorum queues in my test bed. Also, Trixie is running Python 3.13, and I've heard Eventlet is still not 100% compatible with it. Having Epoxy in Trixie is nice, because this means Bookworm users will be able to skip Dalmatian, and we're now aligned with the SLURP thing. As always, bug reports are welcome. Cheers, Thomas Goirand (zigo)
