by Winicius Allan 16 Feb '26

16 Feb '26

Hi kolla o/ I was searching to see if Kolla currently supports migration from OVS to OVN, and I've found this email thread [1]. I'd like to know if this feature has been implemented, and if so, what the necessary steps are. [1] https://lists.openstack.org/pipermail/openstack-discuss/2023-March/032785.h… Best regards

OpenStack Ops Radio Hour Survey - Timing, cadence and more
by Ildiko Vancsa 11 Feb '26

11 Feb '26

Hi All, I’m reaching out to you to draw your attention to the new OpenStack Ops Radio Hour Survey! As a reminder, the OpenStack Ops Radio Hour gathering is a meeting series in a casual setting for operators, engineers, and contributors to come together, share knowledge, and collaborate on the complexities of managing and deploying OpenStack environments. The group organizers put together a survey to better understand what channels people use to learn about upcoming meetings, what topics they would be interested in discussing, and what timing and cadence would be most suitable for folks onwards. You can find the survey here: https://openinfrafoundation.formstack.com/forms/openstack_ops_radio_hour_su… Your input is very important to make the gatherings as widely available and inclusive as possible! Please fill out the survey __by February 25, 2026.__ In the meantime, the next Ops Radio Hour is scheduled to happen on February 27th, 2026 at 1300UTC. You can find more information, agenda items and notes and recordings from previous meetings here: https://etherpad.opendev.org/p/openstack_ops_radiohour Please let me know if you have any questions or run into any challenges with the survey. Thanks and Best Regards, Ildikó

How to access OpenStack instances from the bastion node when deploying OpenStack using Kolla-Ansible
by ussefelboukhari＠gmail.com 11 Feb '26

11 Feb '26

In test environments, some users choose to build their infrastructure inside KVM virtual machines, while others use cloud instances such as EC2 bare-metal that support nested virtualization. After deploying OpenStack, many of them face a major issue: they are unable to access their OpenStack instances. I encountered the same problem myself. After several weeks of intensive troubleshooting, I eventually found a solution. That is why I would like to share this solution with others who face the same issue, and hopefully contribute to the OpenStack community by providing recommendations that could be added to the official OpenStack documentation.

[kolla-ansible][rabbitmq] RabbitMQ cluster creation took too long
by Nguyễn Hữu Khôi 10 Feb '26

10 Feb '26

Hello. I am deploying OpenStack 2025.1 with Kolla-Ansible 2025.1 (master branch) using the latest images. However, when I created a RabbitMQ(4.0.x) cluster with 3 nodes, it took too long—around 12 minutes(it stucked at DB: virgin node -> run peer discovery). I then changed the images to RabbitMQ version 3.13.7, and it worked well. My OS: Ubuntu 24.01 Nguyen Huu Khoi

The Problem: 1. in Skyline both storage nodes are shown but both are shown with the same size of one of both. 2. When I created a Volume then it was created on the other host as shown (in DB, skyline and so on) Anyone an idea what I can do to correct this problems ? Thanks a lot for your help !

[ironic] A first-class physical location API?
by Jay Faulkner 03 Feb '26

03 Feb '26

Something I've seen come up in a few discussions over the last couple of cycles is the need for Ironic to contain more useful information about the physical world. It's made me wonder if there's an opportunity to add bigger support for physical characteristics/locations? I'm thinking metadata like: - Datacenter the server is in - Computer room (or other DC subdivision) - Row - Rack - Slot # - Physical cabling (e.g. what switches you might be connected to and how) Do other folks see this need? I'm trying to tease out if there's something here or not, so just curious about use cases and what people think. -Jay

[neutron] IPv6 DVR for OVN - Seeking feedback on patch review prospects
by Maximilian Stinsky-Damke 03 Feb '26

03 Feb '26

Hello, I'm reaching out about the IPv6 DVR feature for OVN (bug #1998609: https://bugs.launchpad.net/neutron/+bug/1998609) and the associated patch (https://review.opendev.org/c/openstack/neutron/+/867513) As noted in the bug comments, Roberto Bartzen Acosta maintained this patch across multiple release cycles, but it hasn't received reviews from core maintainers and is currently blocked by merge conflicts. Roberto mentioned that the feature hasn't been getting traction despite the work put in. This feature would enable distributed routing for IPv6 GUA addresses in OVN deployments, similar to how IPv4 FIPs work with DVR today. The spec was approved and merged (https://review.opendev.org/c/openstack/neutron-specs/+/867979) indicating community interest. Before I invest time rebasing the patch and resolving merge conflicts, I'd like to understand: 1. Are there technical or architectural concerns that have prevented review? 2. Is there a reason this hasn't been prioritized, or is it a matter of reviewer availability? 3. Would core maintainers be willing to review if the patch is rebased and updated? I'm happy to do the rebase work, but I'd prefer not to spend time on something that won't be merged. Any guidance on the status and viability of this feature would be appreciated. Thanks, Max

We had excellent representation from many different countries and organizations. Lots of good perspective and ideas were shared and I am eager to get started! As promised, here is the recording for those that were not able to attend: https://zoom.us/rec/share/QLyhngha_pgXEc2736oPEdDGWz_UI8IZLbHbJGyDWLv7nt4es… And here is the etherpad where we took notes, but will also continue to use going forward for meeting agendas and general working group coordination: https://etherpad.opendev.org/p/Digital-Sovereignty-WG If you watch the recording, please feel free to add your name to the attendees list in the etherpad, just make an additional note that you watched the recording. Everyone is encouraged to add to the notes and content in the etherpad whether they attended the meeting live or watched the recording. The goal is to capture as much participation as possible. Digital sovereignty is a very important topic with an ever developing list of accompanying legislation and we need everyone's perspective! Now, while there wasn't much in the way of immediate todo's, the one request that I have is that folks fill out this poll so that we can select a meeting time <https://beta.framadate.org/polls/5f355daf8e4329e1cd52> for the next one (during the first week of February).

[keystone][openstack-helm][kolla] Is it safe to run the Keystone wsgi application in multiple threads?
by Vladimir Kozhukalov 30 Jan '26

30 Jan '26

Hi Keystone team, I am writing to ask someone from the Keystone team to give their opinion regarding whether it is safe to run the Keystone wsgi app in multiple threads in the same process. I see [1] Kolla team allows users to configure the number of processes but not the number of threads. We in Openstack-Helm have a similar review request [2] and we had a small discussion about this. I would really appreciate it if someone from the Keystone team can give their opinion on [2]. Thanks. [1] https://opendev.org/openstack/kolla-ansible/src/branch/master/ansible/roles… [2] https://review.opendev.org/c/openstack/openstack-helm/+/971751 -- Best regards, Kozhukalov Vladimir
