[neutron][ml2/ovn] unintended changes in trunk status ACTIVE
by Bence Romsics 15 May '25

15 May '25

Hi Neutron Team, A heads up to OVN folks: We believe we have a problem in Neutron that we move a trunk to ACTIVE status too early (changing the meaning of status=ACTIVE) - already after its parent port is updated to ACTIVE instead of waiting for all of its ports (parent and sub) to be processed. We discovered this while working on this bug: https://bugs.launchpad.net/neutron/+bug/2095152 The problem was introduced by this patch: https://review.opendev.org/c/openstack/neutron/+/853779 Which was intended to be a fix for ml2/ovn leaving a trunk in DOWN after live migration. However that patch affected all backends. And affected not just live migration, but create too. We have proposed the following patch to limit the effect to ml2/ovn (but did not yet find a way to avoid affecting create): https://review.opendev.org/c/openstack/neutron/+/949217 However due to ml2/ovn's handling of trunk subports (not cascading the parent's binding:host update to all subports in the neutron api layer) I don't know how this should be fixed for ml2/ovn. Maybe a clever wait in the OVN databases could solve this. People with better OVN knowledge may want look into this. You're also welcome to review our proposed patches, including this os-vif change to prevent a resource leak in ml2/ovs when a trunk is already deleted on server side when the agent is still processing its create: https://review.opendev.org/c/openstack/os-vif/+/949736 Thanks, Bence (rubasov)

[horizon][memcached]
by Kamil Madac 14 May '25

14 May '25

I have deployed openstack 2024.2 with kolla-ansible in HA setup with 3 control nodes. Everything works without issues, but when I stop memcached node with IP address 192.168.56.12 (or when node goes down), it is not possible to login to Horizon with error message: Something went wrong! An unexpected error has occurred. Try refreshing the page. If that doesn't help, contact your local administrator. In horizon log I have an error message: 2025-05-12 18:05:37.406588 Internal Server Error: / 2025-05-12 18:05:37.406613 Traceback (most recent call last): 2025-05-12 18:05:37.406615 File "/var/lib/kolla/venv/lib64/python3.9/site-packages/django/core/handlers/exception.py", line 55, in inner 2025-05-12 18:05:37.406617 response = get_response(request) 2025-05-12 18:05:37.406619 File "/var/lib/kolla/venv/lib/python3.9/site-packages/horizon/middleware/simultaneous_sessions.py", line 30, in __call__ 2025-05-12 18:05:37.406621 self._process_request(request) 2025-05-12 18:05:37.406623 File "/var/lib/kolla/venv/lib/python3.9/site-packages/horizon/middleware/simultaneous_sessions.py", line 37, in _process_request 2025-05-12 18:05:37.406625 cache_value = cache.get(cache_key) 2025-05-12 18:05:37.406627 File "/var/lib/kolla/venv/lib64/python3.9/site-packages/django/core/cache/backends/memcached.py", line 75, in get 2025-05-12 18:05:37.406628 return self._cache.get(key, default) 2025-05-12 18:05:37.406630 File "/var/lib/kolla/venv/lib/python3.9/site-packages/pymemcache/client/hash.py", line 347, in get 2025-05-12 18:05:37.406632 return self._run_cmd("get", key, default, default=default, **kwargs) 2025-05-12 18:05:37.406634 File "/var/lib/kolla/venv/lib/python3.9/site-packages/pymemcache/client/hash.py", line 322, in _run_cmd 2025-05-12 18:05:37.406636 return self._safely_run_func(client, func, default_val, *args, **kwargs) 2025-05-12 18:05:37.406637 File "/var/lib/kolla/venv/lib/python3.9/site-packages/pymemcache/client/hash.py", line 199, in _safely_run_func 2025-05-12 18:05:37.406639 result = func(*args, **kwargs) 2025-05-12 18:05:37.406640 File "/var/lib/kolla/venv/lib/python3.9/site-packages/pymemcache/client/base.py", line 687, in get 2025-05-12 18:05:37.406642 return self._fetch_cmd(b"get", [key], False, key_prefix=self.key_prefix).get( 2025-05-12 18:05:37.406644 File "/var/lib/kolla/venv/lib/python3.9/site-packages/pymemcache/client/base.py", line 1133, in _fetch_cmd 2025-05-12 18:05:37.406645 self._connect() 2025-05-12 18:05:37.406647 File "/var/lib/kolla/venv/lib/python3.9/site-packages/pymemcache/client/base.py", line 424, in _connect 2025-05-12 18:05:37.406648 sock.connect(sockaddr) 2025-05-12 18:05:37.406650 ConnectionRefusedError: [Errno 111] Connection refused so horizon tries to connect to memcached node which is down. I have default kolla-ansible config with enabled memcached and horizon config is following: SESSION_ENGINE = 'django.contrib.sessions.backends.cache' CACHES['default']['LOCATION'] = ['192.168.56.11:11211','192.168.56.12:11211 ','192.168.56.21:11211'] When I stop any other memcached node, horizon is working without issues. Why is that exact node important for the horizon? Does anyone else have the same experience? Thanks for any advice. -- Kamil Madac

[nova] os-traits release?
by Michael Still 13 May '25

13 May '25

Hi, I tried on IRC but it didn't work out. I realised the other day that I still need an os-traits release for the sound and USB traits that I added a while ago in support of my VDI work. I need those to land before I can really do much more in Nova with the VDI patches. I looked at proposing a release myself, but I couldn't find any documentation on how to actually run the tools for a release independent release. So... Either are there docs on how to do that thing, or could someone do it for me? Thanks, Michael

[tempest][swift][ceph][radosgw] debugging intermittent failures of test_upload_too_many_objects
by Michael Sherman 13 May '25

13 May '25

In our clouds, we're using ceph rgw to provide the s3 and swift object store interfaces. Recently, we began running non-admin tempest smoke tests against the live clouds, and observe intermittent failures for the object store test_upload_too_many_objects test, where the rgw seemingly fails to enforce the number of objects quota. Tempest is running on the most recent master commit, cloud deployed via Kolla ansible 2023.1, and ceph currently on Pacific, deployed via cephadm. It's not a critical issue in our case, but I'd like some advice on getting to the bottom of it. Thanks! Mike Sherman

[oslo] Request to merge the new threading backend in oslo.service.
by Daniel Bengtsson 13 May '25

13 May '25

Hi everyone, Hope you’re all doing well! Just a quick note regarding the current patch for the new threading backend in oslo.service. I have already made a few updates, like: • Adding an issues section to the release note • Renaming the [extras] entry in setup.cfg for clarity For the remaining suggestions, I was wondering if you’d be open to merging the current implementation as-is so the new backend is available and then I can follow up with smaller patches. I’m planning to open a few tickets for: • Merging the common files into one • Adding functional tests • Adding a get_backend_type() helper • And more refinements There doesn’t seem to be anything blocking at this point, and nothing that would impact the API or design significantly. Also, from a functional point of view, we’ve already seen successful results when running this in Nova. Let me know what you think and thanks again for all the feedback and reviews! -- Daniel Bengtsson Software engineer

[tc][all] OpenStack Technical Committee Weekly Summary and Meeting Agenda (2025.2/R-20)
by Goutham Pacha Ravi 12 May '25

12 May '25

Hello Stackers, We're at milestone-1 of the 2025.2 "Flamingo" release cycle [1]. This bug-targeting deadline is usually also a good checkpoint to review design specifications, plan feature reviews, and request releases of libraries and clients. In the past week, members of the OpenStack Technical Committee participated in a meeting to review guidelines for the use of Artificial Intelligence to make code/documentation contributions to OpenInfra projects. The meeting [2] focused on improving the current policy for AI-generated content [3], reacting to recent developments. The use of generative/predictive/agentic AI tools is pervasive in our field, and it may be untenable to impose blanket restrictions. So there were some suggestions around situations of use with interesting perspectives. The OpenInfra Board will continue to deliberate this, and your opinions are welcome. TC members also participated in the OpenInfra AI working group [4] meeting where FPT SmartCloud shared their experience running an OpenStack cloud purpose-built for AI workloads. Details regarding this meeting and future meetings are available on the OpenInfra AI WG mailing list [5]—do consider joining. There were no new governance changes merged last week, but several are currently under review. === Weekly Meeting === The last weekly meeting of the OpenStack Technical Committee was held simultaneously over video [6] and IRC [7] on 2025-05-06. We discussed follow-ups to the resolution to extend the scope of the OpenStack Vulnerability Management Team [8]. We also continued our discussion about the sustainability of OpenStack Special Interest Groups [9] from the past week. SIGs require far less structure compared to project teams, and this is by design. However, there is a lack of information on how one can join many of the SIGs we have. An obvious way would be to reach out to the chairs listed on the SIG. However, in several cases, the chairs are no longer running the SIGs. There's community interest in several SIGs, so the TC intends to health-check each of the SIGs over this release cycle and brainstorm ways to improve their visibility and onboarding practices. We then moved on to a topic from the PTG about improving the contributor experience. The TC is focusing on improving the asynchronous workflow for a better developer experience. Members identified several pitfalls: - Onboarding to projects is difficult even for experienced contributors new to a repo -Many teams do not hold meetings they advertise - Patches often receive no reviews, and asking for reviews on IRC can be discouraging - Contributors are unsure who to ping for reviews This is an ongoing topic of discussion for us, and we don't have resolutions yet; however, project teams are encouraged to audit their contributor landing pages (we coyly called these "So you want to contribute...") to ensure they are up to date with information on how contributors can work with project maintainers. I'd also like to remind you that Jeremy Stanley (fungi) shared two surveys to this mailing list that could use your input as contributors [10] and project maintainers [11]. Having the information sought in these surveys will be crucial for us to improve the community and keep the OpenStack community sustainable. Please take these surveys and share them! The next weekly meeting of the OpenStack Technical Committee is today, 2025-05-13. This meeting will be held in the #openstack-tc channel on OFTC at 1700 UTC. Please find the agenda and other details on the meeting's wiki page [12]. I hope you're able to join us. === Governance Proposals === === Open for review === - Clarify actions when no elections are required | https://review.opendev.org/c/openstack/governance/+/949431 - Require declaration of affiliation from TC Candidates | https://review.opendev.org/c/openstack/governance/+/949432 === Upcoming Events === - 2025-05-13: OpenInfra Board Meeting: https://board.openinfra.org/ - 2025-05-22: OpenInfra UG Meetup, Sweden: https://www.meetup.com/openinfra-user-group-sweden/events/306139678/ - 2025-06-03: 15 ans d'OpenStack - OpenInfra UG, Paris: https://www.meetup.com/openstack-france/events/307492285 - 2025-06-05: OpenStack 15 ans! - OpenInfra UG, Rennes: https://www.meetup.com/openstack-rennes/events/306903998 - 2025-06-28: OpenInfra+Cloud Native Day, Vietnam: https://www.vietopeninfra.org/void2025 === How to Contact the TC === You can reach the TC in several ways: - Email: send an email with the tag [tc] on this mailing list. - Ping us using the 'tc-members' keyword on the #openstack-tc IRC channel on OFTC. - Join us at our weekly meeting: The Technical Committee meets every week on Tuesdays at 1700 UTC [12].
