[oslo][all] Proposing oslo.wsgi
by Stephen Finucane 12 Nov '25

12 Nov '25

o/ I'd like to propose the creation of a new "oslo.wsgi" project that service projects should adopt, where it makes sense to. My reasons for this proposal are three-fold: * As we've been working on the OpenAPI work for various services, we've found ourselves copy-pasting a lot of the code between these services. This has occasionally led to issues when those copies are incomplete [1][2]. Historically speaking, copy-pasting of code between services is a sure sign that this code should be generalised and placed in an oslo library * I have previously noted [3] that oslo.service contains some non- eventlet-related WSGI routing code, and there are questions around whether (a) that code should have been placed there in the first place and (b) how we can maintain that long-term once the eventlet code is removed (the 'oslo_service.wsgi' module has side effects since it imports the backend configuration stuff). * I have also raised some concerns around our use of paste.deploy and routes [1], both of which are minimally maintained nowadays. Many oslo libraries are designed to abstract their underlying libraries, allowing users to switch between e.g. different messaging backends (oslo.messaging) or caching services (oslo.cache). Taken together, I think now would be a good time to provide a new library. I have an initial prototype available [4] which is effectively just a refactoring of the code from oslo.service, but I expect to add both more functionality to this existing code from existing consumers (Nova, Manila, Cinder etc.) and to add the openapi validation machinery. I imagine longer-term, this should evolve to allow us to replace the underlying libraries. However, we should obviously not get into the business of writing our own web framework. I also don't think it would make sense for all services to adopt all aspects of this project, since not all projects have any OpenAPI efforts ongoing at the moment and not all of them use the pastedeploy-routes-webob combo. Given the above rationale and caveats, what do people think? Are there any objections to this idea? Please let me know. If there is not, I will go figure out how to get the ball rolling on this. Cheers, Stephen PS: Why oslo.wsgi instead of a more generic name like debtcollector or futurist? I don't think this library will be useful outside of OpenStack, so the oslo prefix makes sense.

[watcher] 2nd call for maintainers - MAAS integration
by Douglas Viroel 12 Nov '25

12 Nov '25

Hi all, The Watcher team had a session[1] during the last PTG about the impacts of service integrations that have lacked maintainers, documentation, and/or testing coverage in CI. The MAAS (Metal As A Service) integration still lacks maintainers and is impacting the eventlet removal effort within Watcher, since it contains eventlet-dependent code that requires maintenance and validation. In the 2025.2 development cycle, we had a first call for maintainers[2] and we didn't receive any feedback. This is a second call for maintainers interested in supporting MAAS in Watcher, to help fill these gaps (eventlet removal, CI testing, documentation). The Watcher team plans to *deprecate* this integration during the 2026.1 cycle if we don't find anyone to assist in maintaining it. [1] https://etherpad.opendev.org/p/watcher-2026.1-ptg#L177 [2] https://lists.openstack.org/archives/list/openstack-discuss@lists.openstack… Thanks and regards, -- Douglas Viroel - dviroel

[Kolla-Ansible][Tacker] [VIM]Unable to find key file for VIM
by josem.arco＠uah.es 12 Nov '25

12 Nov '25

Hi All, I have installed an bare-metal server Ubuntu 24.04 with Kolla-Ansible and all-in-one with Tacker. When I register the OpenStack Vim with the CLI I have this error “Unable to find key file for VIM e255b2e2…”. I have tried with the two optios of the 'cert_verify' parameter but it doesn’t work. I have also tried to do it with Horizon and it says “Error: Failed to register VIM. Details The request you have made requires authentication.” I have followed the lastest web pages of Kolla and Tacker. Thanks in advance for your help. Jose

Add Trait requirement to running Instances
by Kees Meijs | Nefos 12 Nov '25

12 Nov '25

Hi list, We're looking for a method to add Trait requirements to already running Instances, forcing certain placement upon resize or migration of them. Is there a clean way to do this? Or is there database surgery (which is acceptable to some extend) needed, and how? Thanks!

[all] PSA: requirements-check job no longer normalises underscores with hyphens
by Stephen Finucane 12 Nov '25

12 Nov '25

o/ Sean Mooney noted earlier today that watcher's requirements-check job has started failing with the following warning: Validating requirements.txt WARNING: possible mismatch found for package "microversion_parse" Attribute "package" does not match "microversion_parse" does not match "microversion-parse" Requirement(package='microversion_parse', location='', specifiers='>=0.2.1', markers='', comment='# Apache-2.0', extras=frozenset()) Requirement(package='microversion-parse', location='', specifiers='', markers='', comment='# Apache-2.0', extras=frozenset()) ERROR: Could not find a global requirements entry to match package microversion_parse. If the package is already included in the global list, the name or platform markers there may not match the local settings. This is almost certainly due to recent changes in the openstack/requirements repo to remove use of the soon-to-be-removed pkg_resources library [1]. Its replacement for this use case - packaging - does normalisation slightly differently and it seems it doesn't replace underscores with hyphens. While this could be fixed with custom normalisation in the requirements repo, I don't believe it's wise to do so as that custom normalization would need to be copied anywhere else that needs to parse OpenStack requirements.txt files and requirements more generally. I would instead encourage affected projects to fix the names used in their various requirements.txt files and use the correct PyPI names. From a quick look at failing requirements-check jobs in recent days [2], there aren't many: I see neutron has already fixed the issue [3] and I've proposed a fix for tap-as-a-service [4]. Those patches should prove how small a task this should be. Hope this helps, Stephen [1] https://review.opendev.org/c/openstack/requirements/+/960845 [2] https://zuul.opendev.org/t/openstack/builds?job_name=requirements-check&res… [3] https://review.opendev.org/c/openstack/neutron/+/965188 [4] https://review.opendev.org/c/openstack/tap-as-a-service/+/966782

List Limits returns Null in Nova Unified Limits
by Tyler Wilson 11 Nov '25

11 Nov '25

Hello All, I'm looking into testing out the Nova unified limits, however I am experiencing an odd issue where the 'limit list' returns no data. The 'limit create' and 'limit show' (with the UUID from the create command) seem to work fine. Paste data for the output is here: https://pastebin.com/sPZgZDEK I've even tried sending a GET to http://KEYSTONE_IP:5000/v3/limits with the output of [] ({"limits": [], "links": {"next": null, "self": "http://KEYSTONE_IP:5000/v3/limits", "previous": null}}) The log in keystone WSGI just shows a 200 for the GET request, not much else I could find. Should this work in the way I am expecting here? Or am I missing something? Thanks for any and all assistance!

[cinder][PTG] 2026.1 Gazpacho PTG summary
by Jon Bernard 11 Nov '25

11 Nov '25

Hello everyone, thanks for a very productive PTG for the Gazpacho cycle. Below is a brief summary of the highlights. The raw etherpad notes are here [1] and both the summary and transcribed etherpad notes are captured in out wiki here [2]. # Retrospective We spent time discussing the good and not-so-good of the flamingo cycle. Unsurprisingly, code reviews continue to be our most significant opportunity for improvement. We reviewed what a core reviewer is and how to work towards becoming one, including the metrics that we use to determine eligibility and what we look for in a potential core reviewer. I encourage anyone interested in contributing the project to reach out, in addition to our guideline document on the review process, we're happy to answer questions and help guide folks through the process. # Festival of Reviews We are reworking our 'festival of reviews' meeting to better accommodate a larger set of potential patches. Previously it focused on very small patches that were easier to review, but feedback suggests that time spent as a team on larger reviews would yield a more desirable result. Last Friday we ran the modified format and it seemed to work quite well. # 3rd Party CI This cycle 3rd party CI is required for patches to be reviewed. In the flamingo cycle we saw some challenges with deploying and configuring the software factory setup required to operate a CI. We remain committed to helping vendors sort out any remaining problems, and want to avoid any further slipping on our requirements, as one-off exceptions do not scale. # Eventlet Removal There will be significant focus this cycle on the removal of eventlet from our codebase. Our goal is to have this work completed before M2. The remaining issues and technical challenges were discussed, including some struggles with our multi-backend and it's use of sqlalchemy. We learned that the oslo team is working on some code that may help with this effort. We may have finally found a use for the rally job, unfortunately it has been broken for some time, we will try to get this fixed and reporting useful results this cycle as well. # Driver Block Geometry An original patch to the RBD driver was proposed to make configuring block geometry an option for the operator. Upon inspection, we decided make this option available for all drivers. Discussion about exact location given out driver class model, we have a way forward. https://review.opendev.org/c/openstack/cinder/+/658283 # Per-Tenant SVM Creation Doug Goldstein showed up and blew our minds with a proof-of-concept feature he added to the NetApp driver. This change allows the driver to create per-tentant SVMs and map them to dynamically created backends. There will be some technical hurdles to overcome, but the idea in theory could work. Doug is going to work to propose a patch upstream and with the NetApp team to see if it can take shape. # OpenAPI Stephen has had patches up for openAPI compliance for far too long. We don't have any technical objections to the effort. Brian and I committed to working through the proposed patches at the very start of the cycle. Significant progress already, should be completed soon. # Reverting To Any Snapshot Currently you can only roll a volume back to the last available snapshot. We would like to be able to select any snapshot as a rollback target. Technical requirements were discussed, including the need for a spec. Hoping to see progress on this effort in this cycle. # Clone Across Pools We are interested in improving our implementation for cloning a volume across different pools. The code itself has some distinct shortcomings and Rajat identified several opportunities for improvement. Feedback on current usage was requested, we discussed volume caching as part of these improvements. A path forward was defined and spec should follow. # NFS Driver Feedback Fernando has been working on several improvements to the generic NFS driver and requested feedback. NetApp offered valuable suggestions, some improvements to our tempest testing patches are forthcoming, and a direction forward is understood. # Replication Feedback We solicited feedback on replication, its current usage, and the features it may require to see wider adoption. Questions and answers were discussed, hoping to see a spec capturing the most valuable changes in this cycle.

[PTG] Call for Summaries, Attendance Numbers, and Team Photos
by Kendall Nelson 10 Nov '25

10 Nov '25

Hello Folks! I am working on a summary post for our OpenInfra Blog as usual and I am missing A LOT of attendance numbers from OpenStack teams. Specifically, I am missing attendance numbers from: - Barbican - Blazar - Cinder - Cloudkitty - Cross Deploy - Designate - Eventlet Removal - Glance - Heat - Horizon - i18n - Ironic - Keystone - Kolla - Magnum - Neutron - OpenStack Ansible - OpenStack Helm - Sunbeam - Swift - Tacker - Telemetry - Watcher If you were a moderator for this session please send me your approximate attendance to ptg(a)openinfra.org ASAP. If you simply attended one of these sessions, and you would be so kind as to remind the moderator to send me the info I would be very grateful! Additionally, I will happily accept any team photos that were taken and links to blog posts or other summaries that I can include in OpenInfra Blog post as well. There are a lot of open source communities outside of the OpenInfra Foundation that are curious about how we conduct our PTGs and these posts are incredibly helpful at educating others on how to follow the four opens and build a stronger community. Thank you for all of your support! Looking forward to the next PTG! -Kendall
