[oslo] python-consul2 is unmaintained
by Takashi Kajinami 21 Apr '25

21 Apr '25

Hello, I recently noticed that python-consul2 library[1], which is used by the consul coordination driver in tooz, hasn't been updated for 3+ years. Looking at issues in the project, there is an indication that the library is not compatible with ACL API in consul >= 1.11[2]. There is another fork created[3] and this includes fixes to support new API endpoints. Although the driver in tooz does not directly use the feature, I think it's better to discuss our plan to mitigate risks caused by the unmaintained library. As far as I can think of, there are three options now 1. Deprecate consul driver and remove it 2. Keep using python-consul2 now. At least basic functionality is proven to work by our functional tests (Note that the tests do not cover all configuration patterns) 3. Replace python-consul2 by py-consul Before we start the overall discussions I'd like to ask a few questions to the wider audience, as our inputs. - Is anyone using the consul coordination driver now ? - Does anyone have experience with python-consul2 and/or py-consul ? Note that this discussion affects the http messaging driver[4] currently proposed, because it also requires client library to communicate with Consul. Actually I noticed the situation when I noticed that the requirement check job is failing because the library is not part of global requirements list... Thank you, Takashi Kajinami [1] https://github.com/poppyred/python-consul2 [2] https://github.com/poppyred/python-consul2/issues/42 [3] https://github.com/criteo-forks/py-consul [4] https://review.opendev.org/c/openstack/oslo.messaging/+/912499 -- Takashi Kajinami irc: tkajinam github: https://github.com/kajinamit launchpad: https://launchpad.net/~kajinamit

[octavia] Purging ERROR'ed amphora and load balancers stuck in transitional states

Is there any API way to purge these out of Octavia's service state, or would (very careful) DB hackery be required here?

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...

[openstack-helm] Merge openstack-helm and openstack-helm-infra git repos
by Vladimir Kozhukalov 31 Mar '25

31 Mar '25

Hi dear Openstack-Helmers, I would like to suggest merging the two project git repos: https://opendev.org/openstack/openstack-helm-infra.git https://opendev.org/openstack/openstack-helm.git At some point it seemed reasonable to have separate git repos for openstack and infrastructure charts. But now it looks like we are experiencing more cons than pros. When working on some features we are forced to prepare sets of interdependent patches. Some code can be deduplicated. Also when we publish charts we append two commit hashes as package metadata. Also we can reduce the number of test jobs if we have all chats in one repo. Other people also proposed this earlier. So if there are no objections let's make it done. I understand this is going to affect many of our users. Please express your opinions so we don't break any downstream. If we all agree about this, then I would say we can do this in the mid of March/2025 before 2025.2 PTG. The procedure is going to be smth. like 1. Freeze the infra repo and prepare retirement PSs for it 2. Merge openstack-helm-infra repo into openstack-helm ``` git clone https://opendev.org/openstack/openstack-helm.git cd openstack-helm git remote add infra https://opendev.org/openstack/openstack-helm-infra.git git fetch infra git checkout -b infra infra/master git checkout master git merge --allow-unrelated-histories infra # resolve not so many conflicts git review ``` 3. Accept merger PS 4. Update documentation 5. Accept infra retirement PSs (openstack-helm-infra and project-config) -- Best regards, Kozhukalov Vladimir

[mistral][heat][watcher][aodh] croniter being abandoned
by Thierry Carrez 22 Mar '25

22 Mar '25

Hi everyone, It was brought to my attention that the croniter maintainer has decided to abandon his project, due to not wanting to deal with his perceived exposure to the EU Cyber-Resilience act (CRA). https://pypi.org/project/croniter/#disclaimer The maintainer indicates that you should no longer use it and it may be "unpublished" any time after March 15, 2025. Croniter is being used in at least Mistral, Heat, Watcher, and Aodh as a dependency. While this is clearly an overreaction (the CRA only applies to "economic operators" putting "products with digital elements" on the market "in the course of a commercial activity"), we should probably prepare to migrate away from this dependency, or maintain a fork of it. -- Thierry Carrez (ttx)

Hello Everyone, I am currently trying to setup in all-in-one development environment for OpenStack on a Debian VM. The VM has 16 GB RAM and 4 CPUs. However, I face an error while trying to run FORCE=yes ./stack.sh. I get an error that keystone does not start. This causes the entire process to fail. Requesting assistance in solving this issue. I am following the this guide: https://docs.openstack.org/devstack/latest/guides/single-machine.html PFA the error log and error message on the terminal.

[all][tc][ptl][qa] Migrating upstream CI/CD jobs to Ubuntu Noble (24.04)
by Ghanshyam Mann 14 Mar '25

14 Mar '25

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).

[kolla] [nova] API flags ignored in Wallaby
by Albert Braden 12 Mar '25

12 Mar '25

After rebuilding our Train clusters on Wallaby we are seeing some API issues. It appears that flags that work in Train are still documented in Wallaby, but are ignored. Do we have something setup wrong, or are we encountering bugs? The first thing is the “locked” list: Train: openstack server list --all-projects --locked --os-compute-api-version 2.73 <empty list because nothing is locked> openstack server list --all-projects --unlocked --os-compute-api-version 2.73 <list of every VM in the cluster> Wallaby (locked flag is ignored): openstack server list --all-projects --locked --os-compute-api-version 2.73 <list of every VM in the cluster> openstack server list --all-projects --unlocked --os-compute-api-version 2.73 <list of every VM in the cluster> The second problem is the hypervisor list. We can’t get “long” output in Wallaby: Train: openstack hypervisor list --long | ID | Hypervisor Hostname | Hypervisor Type | Host IP | State | vCPUs Used | vCPUs | Memory MB Used | Memory MB | Wallaby (long flag is ignored): openstack hypervisor list --long | ID | Hypervisor Hostname | Hypervisor Type | Host IP | State |
