[neutron] Drivers meeting canceled Friday, October 10th
by Brian Haley 09 Oct '25

09 Oct '25

Hello Neutrinos: I am going to cancel tomorrow's Drivers meeting as there are no topics and I will be out. At this point we should probably just add things to the PTG etherpad and discuss there [0]. Just a reminder there are still open specs that need updates and/or review, list is at [1]. Have a nice weekend! -Brian [0] https://etherpad.opendev.org/p/oct2025-ptg-neutron [1] https://review.opendev.org/q/status:open+project:openstack/neutron-specs

[PTLs] [OpenStack TC] Anonymized User Survey Feedback
by Jimmy McArthur 09 Oct '25

09 Oct '25

As you know each year we conduct an OpenStack User Survey. A big chunk of that survey data is dedicated to OpenStack projects, WGs, etc… I’d like to invite you all to review the anonymized feedback from 2025[1]. Please review not only for feedback, but to determine if you want to update your TC, PTL or WG questions. Additionally, if the TC can ensure that questions are up to date wrt to project or working group status. For example, we know the InteropWG has been disbanded as of this year, so we should probably remove those questions for 2026. We would like to have ALL reviews/requests in no later than December 1, 2025. If we do not hear from your project, we will assume you want no changes. If you have any questions, please let myself or Allison Price know. Cheers, Jimmy [1] https://docs.google.com/spreadsheets/d/1bte_k0R3_rVzFF9ND5zTZV0j9liXI1PxPNo…

[neutron] oslo.messaging and port notifications broadcast
by Thomas Goirand 09 Oct '25

09 Oct '25

Hi, Is it possible, with oslo.messaging, to have 3 daemons to get the Neutron port.{create,update,delete}.end notification events? I tried hard, but no mater how I do it, only one of my 3 daemons get the message. I'm about to add forwarding feature to the other 2 when one receives an event. Is there a better way? Cheers, Thomas Goirand (zigo)

[PTL][release][stable] 2024.1 Caracal transition to Unmaintained
by Elõd Illés 08 Oct '25

08 Oct '25

Hi teams, As 2025.2 Flamingo was released last week and we are in a less busy period, now is the good time to call your attention to the following: At the end of October 2024.1 Caracal is planned to transition to Unmaintained phase [1] (planned date: 2025-10-24). I have generated the list of the current *open* and *unreleased* changes in stable/2024.1 for every repositories [2] (where there are such patches). These lists could help the teams who are planning to do a *final* release on Caracal before moving stable/2024.1 branches to unmaintained/2024.1. Feel free to edit and extend these lists to track your team's progress! Note that the last hash on stable/2024.1 branch will be tagged ('2024.1-eom' tag) and transition patches will be generated soon. After the tagging and cutting unmaintained/2024.1 branch, the new unmaintained branch will be open to for bug fixes, but there won't be official releases for 2024.1 Caracal anymore. (You can get some information about the Unmaintained state on stable policy page [3]). *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! [1] https://releases.openstack.org/ [2] https://etherpad.opendev.org/p/2024.1-caracal-final-release-before-eom [3] https://docs.openstack.org/project-team-guide/stable-branches.html#unmainta… Thanks, Előd Illés irc: elodilles @ #openstack-release

[kolla][kolla-ansible] Managing Object Storage Backend via Kolla-Ansible
by Sara khosravi 07 Oct '25

07 Oct '25

Hello everyone, We are currently using Kolla-Ansible stable/2024.1 to manage our OpenStack deployment, including both core services and the Swift object storage backend. Our goal is to manage all OpenStack services, including object storage, through a unified lifecycle management tool. We understand that managing large volumes of data can affect the performance of other services. To address this, we've separated the data flow entry points that could become bottlenecks into dedicated host groups: a load balancer and a Swift proxy. Specifically, we've created two separate host groups: one for the secondary load balancer (which serves as the initial entry point) and another for the Swift proxy services. 🔹 Key Point 1: Decoupling Swift Traffic We’ve separated the Swift proxy nodes from the other OpenStack API services. This also means that the load balancer handling Swift traffic must be distinct from the main load balancer used for services like Nova, Glance, and Neutron. 🔹 Key Point 2: Keystone Endpoint Behavior Swift still registers with the existing Keystone service. Depending on the configuration: - If the second_loadbalancer is enabled, Keystone publishes the VIP (Virtual IP) of the secondary HAProxy as the Swift endpoint. - If it’s disabled, Keystone uses the direct API address of the Swift proxy node. 🔹 Key Point 3: Two Supported Configurations Kolla-Ansible supports two architecture models for Swift: Normal and Advanced. - Normal Configuration This is the default setup in stable/2024.1, where all OpenStack services, including Swift, share the same load balancer and traffic path. - Advanced Configuration This is recommended for large-scale deployments with heavy data volumes. In this setup, Swift traffic goes through a dedicated load balancer and proxy nodes, which reduces contention and improves performance. We’ve attached an architectural diagram to better illustrate the setup. We’d love to share this approach with the community and welcome any feedback or suggestions. Our goal is to make managing both compute and storage services within a single deployment framework as simple as possible. Thanks in advance for your insights!

[nova] limiting number of attached devices
by Pavlo Shchelokovskyy 07 Oct '25

07 Oct '25

Hi all, we've recently faced a peculiar issue with one of the users, namely: - fat VM with 100 cores - virtio-net multiqueue set up for the VM (`hw:vif_multiqueue_enabled`) - quite a number of NICs attached. On an attempt to attach yet another NIC (~20th), instance crashes with specific error message in the qemu log ``` qemu-system-x86_64: ../../accel/kvm/kvm-all.c:1754: kvm_irqchip_commit_routes: Assertion `ret == 0' failed. ``` After debugging, we believe that what's happening is we are hitting an intrinsic limit of IRQs in a KVM guest ( `KVM_MAX_IRQ_ROUTES 4096` here https://github.com/torvalds/linux/blob/master/include/linux/kvm_host.h#L2175 ). With multiqueue and this number of vCPUs, each new NIC adds ~200 interrupts in the guest, so with some other system ones and some more devices already present, at some point, adding one more NIC overflows this current limit. In this particular case, the problem is exaggerated by the fact that what's requesting the new NIC attachment is some sort of CNI-like automation inside the guest, reacting on some external events (like another k8s node going down and pods being migrated). This got me thinking - should nova be able to somehow hard-limit the number of attached devices to a VM? I do not think nova should be "counting the IRQs" per se, as there are things outside that nova does not necessarily know (like what and how many actual devices a given qemu machine type creates inside the guest). But having some knob on a user side, for example a special metadata set on the instance, or at least an extra spec property for the flavor, could possibly suffice in this case. I'm eager to hear your thoughts on this, please chime in with any ideas on how to prevent such self-destructing instances :-) Best regards, -- Dr. Pavlo Shchelokovskyy Principal Software Engineer Mirantis Inc www.mirantis.com

We understand that handling large volumes of data can impact the performance of other services.

Specifically, we've introduced two host groups: one for the secondary load balancer (serving as the initial entry gateway) and another for the Swift proxy services. 🔹 **Key Point 1:** We've decoupled the Swift proxy from other OpenStack API services. As a result, the load balancer for Swift must also be isolated from the main load balancer handling other APIs. 🔹 **Key Point 2:** The Swift service registers itself with the existing Keystone service.

[tc][all] OpenStack Technical Committee Weekly Summary and Meeting Agenda (2026.1/R-25)
by Goutham Pacha Ravi 07 Oct '25

07 Oct '25

Hello Stackers, We're officially in the 2026.1 "Gazpacho" development cycle [1]. Congratulations on the successful and timely release of OpenStack's 32nd release: 2025.2 "Flamingo". For more information on the release, the OpenInfra Foundation staff have pieced together a release highlight on the OpenStack website [2], and project maintainers spoke about the release on OpenInfra Live [3] last week. In the past week, as our focus slowly began shifting between release boundaries, the OpenStack Technical Committee welcomed a new Vice-Chair, Michał Nasiadka (mnasiadka). We're exploring options for an alternate weekly meeting timing that could be friendly to our contributors in the Eastern Hemisphere. mnasiadka will be leading these meetings, while we still hope to continue a good cadence on our existing weekly meetings. I'll bring you more details about this change as we finalize the details. We're also actively planning sessions for the upcoming OpenInfra PTG. The OpenStack TC etherpad is available for you to propose topics [4]. Please feel free to add a topic along with your nick and timezone so we can coordinate a final schedule during the PTG week, avoiding as many conflicts as possible. In the past week, the TC appointed Felipe Reyes (freyes) as the PTL to the OpenStack Charms project [5]. We extended the "inactive" status of the Monasca team through the 2025.2 release cycle, and a decision on its retirement is imminent. There are similar proposals regarding other teams that had no PTL nominees in this past round of elections. === Weekly Meeting === The TC weekly meeting on September 30th 2025 [6] focused primarily on addressing leaderless projects and filling key TC roles. The committee proposed to mark both the Venus and Vitrage project teams as "inactive" and notify the openstack-discuss mailing list, as neither team has found a new Project Team Lead (PTL) so far. The Gerrit activity on both these projects has shown a slowdown, which could either mean maturity and stability, or lack of maintenance. Continuous integration system jobs are failing for some of the deliverables; therefore, they're not release-worthy for now. If maintenance and development activity does not resume over the 2026.1 release cycle, the deliverables will be retired. We discussed the need for TC liaisons to the Freezer, Oslo, Release Management, and Requirements projects. Sylvain Bauza (bauzas) and I will continue being the OpenStack VMT liaisons. We noted progress on the recent community engagement regarding Skyline's health and patch merging [7], and discussed plans to mentor one or more new core maintainers, and possibly hold a dedicated slot at the upcoming PTG (Project Team Gathering) to encourage further engagement. The TC is running an internal poll to find a preferred time slot and format (video vs. IRC) for future meetings, including a request for a slot that better suits EU and APAC time zones. The next meeting of the OpenStack TC is on October 7th 2025. This meeting will be hosted on Meetpad and IRC simultaneously. Please find the meeting's agenda and joining details in the wiki [8]. I hope you'll be able to join us. === Governance Proposals === ==== Merged ==== - Add 2026.1 TC chair and vice-chair | https://review.opendev.org/c/openstack/governance/+/962614 - Extend Monasca's inactive state | https://review.opendev.org/c/openstack/governance/+/959392 - Appoint Felipe Reyes as PTL for OpenStack Charms | https://review.opendev.org/c/openstack/governance/+/962121 - pti: Remove reference to 'python setup.py' | https://review.opendev.org/c/openstack/governance/+/962920 - pti: Update to reference pyproject.toml | https://review.opendev.org/c/openstack/governance/+/962921 ==== Open For Review ==== - Retire Monasca project | https://review.opendev.org/c/openstack/governance/+/953671 - Require declaration of affiliation from TC Candidates | https://review.opendev.org/c/openstack/governance/+/949432 - Mark Vitrage project-team inactive | https://review.opendev.org/c/openstack/governance/+/963227 - Mark Venus project-team inactive | https://review.opendev.org/c/openstack/governance/+/963228 === Upcoming Events === - 2025-10-17: OpenInfra Summit, Paris-Saclay: https://summit2025.openinfra.org/ - 2025-10-27: OpenInfra PTG: https://openinfra.org/ptg/ - 2025-10-04: OpenInfra Board meeting: https://board.openinfra.org/ Thank you very much for reading!

[ironic][power] Anyone using PReP partitioning support?
by Julia Kreger 07 Oct '25

07 Oct '25

Greetings Power folks! The Ironic project is curious if anyone is using PReP partitioning support? Specifically Ironic has long had a code path to manage creation of the PReP partition for booting power hardware as part of the partition image path code, but as time has gone on we're unsure if anyone is actively using this code path on newer versions of Ironic, coupled with the general decline of partition image usage. If anyone is using Power with newer versions of Ironic, please let us know if you're using partition images with Ironic, thus using PReP partitions. Specifically we're curious because we have a discussion topic which has been raised for the upcoming PTG. Thanks! -Julia

[Nova] Need to reschedule the Nova upstream meeting ⏰
by René Ribaud 06 Oct '25

06 Oct '25

Hi everyone, We need to move the current Nova upstream meeting, as most contributors, myself included, are busy in another meeting at that time. Finding a new slot is not straightforward, since some of our meetings are recurring and the daylight saving changes add additional complexity. Over the past few weeks, I tried to narrow down the possible options, and here’s a short poll with different time slots to choose from: https://framadate.org/ao12zK6wR3K3nfbF If none of these options work for you, or if you have other suggestions, please reply to this thread. Please note that we might need to adjust the schedule again later in the year, either due to daylight saving changes or if our other recurring meetings start to overlap again. Thanks for your understanding and input! Cheers, René

[Kolla][Kolla-Ansible] Making the use of mirrors easier on container build
by Michael Still 04 Oct '25

04 Oct '25

Oh hello, For the last couple of years I've been working on trying to improve the VDI experience in OpenStack by enriching our SPICE capabilities. A series of patches has now landed in Nova that enable SPICE native console sessions from outside the cloud, I have a working (but probably not completely finished) SPICE native proxy, and the next step is adding deployment support to Kolla-Ansible so that I can start demoing an end to end implementation. I have a draft of those changes, but don't feel quite ready to push them to Gerrit just yet. As part of that I've been building my own Kolla images in my homelab CI environment for a couple of years now. I don't know about others, but for me by far the most common reason for these builds to fail is because of intermittent connectivity to upstream package repositories -- either flaky networking, random noise, or rate limiting. Increasingly I find myself carrying private patches to use local mirrors instead of the upstream sources. It occurs to me I might not be the only one with this sort of use case. I therefore wonder how the Kolla team would feel about abstracting the upstream sources of various build dependencies so that they were defined centrally? That would make it much easier both to override sources with local mirrors, as well as define exactly what upstream sources are required to conduct a build. If that's a reasonable thing to do, where would people see that list sitting? My initial thought is in the defaults for the kolla-build ansible role, but I am definitely not a Kolla expert so I am open to guidance here.
