[release] Release countdown for week R+0
by Thierry Carrez 26 Sep '25

26 Sep '25

Development Focus ----------------- We will be releasing the coordinated OpenStack 2025.2 "Flamingo" release next week, on October 1st, 2025. Thanks to everyone involved in the 2025.2 "Flamingo" cycle! We are now in pre-release freeze, so no new deliverable will be created until final release, unless a release-critical regression is spotted. Otherwise, teams attending the PTG should start to plan what they will be discussing there, by creating and filling team etherpads. You can access the list of PTG etherpads at: http://ptg.openstack.org/etherpads.html General Information ------------------- On release day, the release team will produce final versions of deliverables following the cycle-with-rc release model, by re-tagging the commit used for the last RC. A patch doing just that will be proposed. PTLs and release liaisons should watch for that final release patch from the release team. While not required, we would appreciate having an ack from each team before we approve it on the 1st, so that their approval is included in the metadata that goes onto the signed tag. Upcoming Deadlines & Dates -------------------------- Final 2025.2 "Flamingo" release: October 1st, 2025 OpenInfra Summit Europe: October 17th-19th, 2025 OpenStack PTG (virtual): October 27th-31st, 2025 -- Thierry Carrez (ttx)

[openstack-ansible][ussuri] moving openstack deployment node to other host
by Danish Khan 25 Sep '25

25 Sep '25

Dear Team, Our controller1 node which was also openstack deployment node somehow crashed and is not accessible now. I am trying to make controller3 as new deployment node. Below is the step which I am planning to follow. I have backup of (openstack-ansible, openstack_deploy and ansible directory of controller1 ): 1. Place /opt/openstack-ansible directory from controller1 to controller3 2. copy /etc/openstack_deploy directory from controller1 to controller3 3. copy /etc/ansible/ directory from controller1 to controller3 4. run bootstrap on controller3 5. test if openstack-ansible has picked same clusters and inventory. Can someone please suggest if this is correct approach or if I am missing something. Regard, Danish

[kolla] [swift] Seeking reviews for reinstating Swift support for 2025.2
by Amir Hossein Ahmadi 25 Sep '25

25 Sep '25

Hello Kolla and OpenStack community, A few months ago, Swift support was removed from the Kolla project due to several challenges, including the need for role modernization, the lack of dedicated maintainership, and persistent CI failures. Following that, I volunteered to take on this effort. Over the last few months, I have been working to address these issues and am happy to report significant progress: - *Modernized Roles:* The Swift roles have been fully updated to align with the latest Kolla and Kolla-Ansible development standards. - *Reliable CI:* The associated Zuul jobs are now consistently green, with all tests successfully validated. - *Maintainership:* I have stepped up to maintain the Swift service within Kolla, ensuring its long-term health and stability. A considerable amount of effort has been invested to ensure this implementation is robust and maintainable for the community. With the *2025.2 release deadline just four weeks away*, the final and most critical step is to get these patches reviewed and merged. Your feedback and reviews are crucial to landing this work in time for the release. Reinstating Swift support would be a valuable addition for many operators. Any time you can spare to look over the patches would be greatly appreciated. You can find the main patch series here: https://review.opendev.org/q/topic:%22dev-swift-modernization%22 Thank you for your consideration and for all your contributions to the OpenStack community. Best regards, Amir Hossein (IRC: amir58118)

Upgrade Caracal --> Epoxy obstacles
by Eugen Block 24 Sep '25

24 Sep '25

Good morning, I just wanted to share some of our experience from this week when we upgraded our production cloud from Caracal to Epoxy (and also Ubuntu 22.04 --> 24.04). It wasn't as easy as previous upgrades, there were a couple of obstacles on the way. # RabbitMQ The main issue was rabbitmq, I'd say. Since the rabbitmq version was 3.9 on Jammy, we had to get to 3.12 for Noble. I had tried a lot of things in my test environment, in the end I decided to reduce the number of rabbitmq hosts to one, upgraded it with podman from 3.9 to 3.10 to 3.11 to enable the feature flags required for 3.12 (all still under Jammy). Then I could upgrade the OS to Noble so the package based rabbitmq-server would start successfully. # Database The recent thread about older password hashes (https://lists.openstack.org/archives/list/openstack-discuss@lists.openstack…) was helpful, we set the same passwords for those system users that came up in the MySQL query, and we didn't notice any issue. But there were two issues we had to deal with regarding the database: During nova-manage db sync we got these errors: 2025-09-22 14:08:19 2 [ERROR] Incorrect definition of table mysql.column_stats: expected column 'hist_type' at position 9 to have type enum('SINGLE_PREC_HB','DOUBLE_PREC_HB','JSON_HB'), fou nd type enum('SINGLE_PREC_HB','DOUBLE_PREC_HB'). 2025-09-22 14:08:19 2 [ERROR] Incorrect definition of table mysql.column_stats: expected column 'histogram' at position 10 to have type longblob, found type varbinary(255). This had not popped up during my tests, but our production database is around 10 years old when we started with our OpenStack journey, my test environment is quite new. What fixed it was: mysql_upgrade check-if-upgrade-is-needed Then there's another thing I have to fully grasp yet, but we now have a ".local" directory in /var/lib/mysql: find /var/lib/mysql/.local/share/containers/storage/ /var/lib/mysql/.local/share/containers/storage/ /var/lib/mysql/.local/share/containers/storage/libpod /var/lib/mysql/.local/share/containers/storage/db.sql Which mysql_upgrade didn't like. I assume that podman created that, but I'm not sure why (I only created a rabbitmq pod). Anyway, I removed that directory so I could proceed with the db sync commands to complete the upgrade process. In my test cloud I removed podman, then restarted galera and the directory is gone, so that's what I'm gonna do in the production as well. # opentack-client Then there are these messages during every openstack command: Could not load 'message_list': module 'zaqarclient.queues.v2.cli' has no attribute 'OldListMessages' Could not load 'message_post': module 'zaqarclient.queues.v2.cli' has no attribute 'OldPostMessages' I'll need to check if they impact any of our scripts, we don't use zaqar, but removing that package would also remove heat, so that won't be possible. # nova-compute: I waited for version 19.2.1 of librbd1 to be released, otherwise nova-compute would fail: qemu-block-extra : Depends: librbd1 (>= 19.2.1-0ubuntu0.24.04.1) but 19.2.0-0ubuntu0.24.04.2 is to be installed # neutron-metadata-agent There's a bug for functioning agents showing as dead, applying the mentioned patches fixes it: https://bugs.launchpad.net/neutron/+bug/2112492 # Pacemaker We use pacemaker for high availability and during the dist-upgrade I had to run 'apt --fix broken', then remove resource-agents and resource-agents-base to get through the dist-upgrade, then install pacemaker and crmsh again afterwards. Not sure if anyone will read this far, but I wanted to get that off my chest. ;-) So obviously, most of the issues weren't really OpenStack issues, but I wanted to share this experience anyway. If you read this far, thanks! ;-) Regards, Eugen

[designate] DNS records stuck in PENDING state but records created succesfully
by Jadon Naas 23 Sep '25

23 Sep '25

Hello! I am using Designate on 2023.2 with a PowerDNS backend. I have a recordset with three A records created through Designate. The A records are stuck in "PENDING" state with action "CREATE" or "UPDATE". The records were successfully created in PowerDNS, and changes are pushed to PowerDNS. However, the record status never finishes updating. Deleting and recreating the recordset results in the same situation. I do not see any notable errors in the logs for Designate or for PowerDNS. I have checked that the Desigate configuration for the nameservers and for the targets match the correct IP addresses for my PowerDNS server and for my Designate service hosts. Would folks have any suggestions for what I could do to determine what is preventing Designate from updating these records or to manually update the status of the records? Thank you! Jadon Naas

[all][tc] Retrospective for OpenStack Elections
by Goutham Pacha Ravi 22 Sep '25

22 Sep '25

Hello Stackers, The OpenStack Technical Committee would like to take a moment to reflect on the recently concluded elections [1][2]. Elections and renewal of governance are a cornerstone of our Open Community principle [3]. We firmly believe that well-governed projects are sustainable and successful. In the recent elections, we saw 78 electors cast their votes to elect members to the TC out of 173 eligible voters. Jeremy Stanley (fungi) is planning to follow up with some more detailed analysis, but I wanted to kick-start this thread to share a few insights and initiate a call-to-action. To be eligible to contest or vote in OpenStack elections, you must meet two criteria: - You must be an Active Contributor, which means you have had a change merged in the roughly one-year period prior to the elections. - You must be an "Individual Member" of the OpenInfra Foundation (not a "Community Member") at the time the electoral rolls are created. This date is published and typically occurs a few days before polling begins. For the recently concluded 2026.1 elections, we identified over 650 active contributors in the one-year timeframe. However, as you can see, the number of eligible voters and the number of actual voters were significantly smaller. We've identified a few key reasons for this: - Individual Membership Renewal: In the past few months, as the OIF has transitioned under the Linux Foundation, we asked all individual members to "renew" their memberships. OIF staff and OpenStack election officials noticed a drop in the electorate due to this new requirement. It's quite easy for an email seeking renewal to get lost in a crowded inbox. - Opt-in for Ballots: We host our elections with CIVS, a free and secure internet voting service. A ballot arrives via email when polling begins, but CIVS will not send you an email unless you have opted in. While we have tried to remind folks to enable these emails, they can still get "lost" in the noise. - Membership Type Confusion: Many of us may not realize that we need to be an "Individual" member of the OIF to participate in the governance process. I feel we need to do a better job of reminding people why this is needed, so they can make an informed choice about whether they'd like to impact the governance of OpenStack. Nearly 500 contributors are currently either "Community" members or have no affiliation with the OIF. We'd like to hear your thoughts and ideas on how we can improve in these areas (are there any more?). What can we do to ensure a wider and more engaged electorate in future elections? We believe that increasing participation is essential for the long-term health and success of the OpenStack community. Thank you, Goutham Pacha Ravi (gouthamr) OpenStack Technical Committee [1] https://lists.openstack.org/archives/list/openstack-discuss@lists.openstack… [2] https://lists.openstack.org/archives/list/openstack-discuss@lists.openstack… [3] https://opendev.org/openinfra/four-opens/src/branch/master/doc/source/openc….

[tc][all] OpenStack Technical Committee Weekly Summary and Meeting Agenda (2025.2/R-1)
by Goutham Pacha Ravi 22 Sep '25

22 Sep '25

Hello Stackers, We're wrapping up work on the 2025.2 "Flamingo" release [1] within all projects that follow the "cycle-with-rc" release model [2]. The coordinated release is scheduled for October 1, 2025. You can follow the cycle highlights that Project Team Leads and liaisons have put together to get a preview of what this release brings [3]. In the past week, election officials posted results from the Combined TC/PTL elections for the 2026.1 release cycle [4][5]. I'm happy to welcome Tony Breeds (tonyb) and welcome back Doug Goldstein (cardoe), Dr. Jens Harbott (frickler), and Sylvain Bauza (bauzas) to the OpenStack Technical Committee. On behalf of the TC, I'd also like to congratulate the newly appointed PTLs of 34 project teams. This includes Arnaud Morin (amorin), who is leading the Mistral project as a first-time PTL, and Li Liu (liliueecg), who is returning to Cyborg as PTL after the Stein release. Thank you all for dedicating your time to fill these important roles. In the past week, the TC didn't merge any new governance changes; however, a few are currently undergoing community review. === Weekly Meeting === The TC held its weekly meeting on OFTC's #openstack-tc IRC channel on September 16, 2025 [6]. We discussed the community's participation in the election process [7] and are seeking input on how the process can be improved. It's possible that any changes we come up with would need buy-in from the OpenInfra Foundation's Board and staff. We followed up on the effort to standardize database character sets and collations across OpenStack projects [8]. The TC agreed that consistency would be beneficial for operators and supported the plan to make this a community goal. We'll follow up regarding the details. We touched on the status of "leaderless" projects, specifically Venus, OpenStack Charms, and Vitrage. If we find no PTL volunteers, the TC plans to follow up with the project teams and discuss options like retirement, finding liaisons and switch projects to a DPL governance model, or moving the projects to a Special Interest Group (SIG). We briefly discussed the upcoming PTG (Project Teams Gathering), with a suggestion to dedicate the first two days to cross-project discussions to encourage collaboration. The meeting concluded with a discussion about vendoring a BSD-3 licensed library, ply, into the yaql project, which the TC approved after confirming the license is compatible with OpenStack's Apache V2 license [9]. The next meeting of the OpenStack Technical Committee is on September 23, 2025. This meeting will be hosted on OFTC's #openstack-tc IRC channel and will begin at 1700 UTC. Please find the meeting's agenda on the wiki [10]. I hope you'll be able to join us there! === Governance Proposals === ==== Open For Review ==== - Add TC/PTL results from 2026.1 election | https://review.opendev.org/c/openstack/governance/+/961598 - Retire metalsmith project from bare metal program | https://review.opendev.org/c/openstack/governance/+/958297 - 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 - Extend Monasca's inactive state | https://review.opendev.org/c/openstack/governance/+/959392 === Upcoming Events === - 2025-10-01: OpenStack 2026.1 "Flamingo" release day - 2025-10-03: OpenStack's Birthday Meetup, Austin: https://www.meetup.com/openinfra-austin/events/310508680 - 2025-10-17: OpenInfra Summit, Paris-Saclay: https://summit2025.openinfra.org/ - 2025-10-27: OpenInfra PTG: https://openinfra.org/ptg/ Thank you very much for reading!

[diversity] [outreachy] Call for mentors for Dec 2025 cohort
by Dmitry Tantsur 22 Sep '25

22 Sep '25

Hi folks! It's the Outreachy time of the year. Despite the enormous financial and organizational difficulties, the December cohort will start soon, and OpenStack is, as usual, a part of it. We're looking for mentors and their projects. Please submit your ideas to https://www.outreachy.org/communities/cfp/openstack/ by this Friday, Sep 26th. You can check my blog post https://owlet.today/posts/how-to-propose-the-best-project-for-outreachy/ on some tips. Note that, just like in the previous cycle, we'll only be able to fund one intern. I still hope we get a few project proposals for interns to choose from. Let me know if you have any questions! Dmitry on behalf on OpenStack community coordinators. P.S. Apologies for the late notice: it took us some time to confirm everything.

[kolla][kolla-ansible] Python dependency handling in custom Ansible module without toolbox
by sarah.kh09＠gmail.com 22 Sep '25

22 Sep '25

Hi everyone, I'm developing a new Ansible module for one of the kolla-ansible roles, and it depends on a Python package that needs to be installed via pip on the target nodes. I understand that Kolla Ansible generally avoids installing Python packages directly on hosts, and prefers handling such dependencies through the kolla_toolbox container. However, in my case: - Deploying a sidecar container isn't feasible within our current architecture - Delegating execution to localhost or kolla_toolbox would introduce complexity that we’d rather avoid Given these considerations, I'm looking for alternative ways to handle this dependency while staying aligned with Kolla's principles of reproducibility and container isolation. Has anyone faced a similar situation or found a clean workaround? Is using kolla-toolbox the only standard and recommended approach in such cases? Thanks a lot for your help and feedback!

[nova] Nova API call duration increases after upgrading to Caracal
by Chang Xue 21 Sep '25

21 Sep '25

Hello, we recently upgraded from Bobcat to Caracal. After upgrading, an interesting increment of duration of nova api call is observed. It's involved to multiple API calls, e.g. os-query-sets, /v2.1/servers/detail, etc. And it seems to be accumulated, meaning whenever nova-api is restarted, the duration seems to be fairly fast, giving response within like 80, 90 ms. As it keeps running for like up to 10 days, the duration increases to over 500 ms. I noticed that Caracal is using UnifiedLimitsDriver instead of DbQuotaDriver. I tried to change nova.conf to use DbQuotaDriver but it seems not working well with reducing the duration. I understand that calling to Keystone and Placement (and likely other external APIs) could result to longer duration, but pretty confused why it shows up as accumulated. Wondering if anyone else in Openstack community noticed the similar issue, thanks!

[aodh]how the evaluation process works
by Nguyễn Hữu Khôi 21 Sep '25

21 Sep '25

Hello, I would like to understand how the evaluation process works. For example, I have this rule: openstack alarm create --name memory_use_test \ --type gnocchi_resources_threshold \ --metric memory.usage \ --threshold 102 \ --comparison-operator gt \ --aggregation-method mean \ --granularity 60 \ --evaluation-periods 3 \ --resource-id dca36039-c603-422c-8366-f6ba4e9539c3 \ --resource-type instance Does this mean that when the alarm-evaluator service is running per a period, it will check the last 3 data points, each aggregated over 60 seconds? Thank you. Regards. Nguyen Huu Khoi

[neutron] VPN service/router stays PENDING_CREATE - 2024.2 Dalmatian
by Shubham Yadav 19 Sep '25

19 Sep '25

Hello OpenStack Community, I'm working with OpenStack VPNaaS (using strongSwan as the backend driver) and have a question about tunnel configuration capabilities. Current Setup: OpenStack VPNaaS with strongSwan driver (StrongSwanDriver) Single VPN Service (gateway) with multiple IPSec Site Connections Each connection targets different remote peers with distinct subnets Configuration Details: VPN Service: Connected to a single router Multiple IPSec Site Connections under the same VPN Service: Connection 1: To MY office (10.10.100.0/24) via peer 68.x.y.34 Connection 2: To Rackspace (172.24.60.0/22) via peer 184.n.p.53 Shared IKE and IPSec policies across connections Local endpoint groups covering multiple subnets (192.168.0.0/24, 10.43.0.0/16) Question: Is it supported/recommended to have multiple IPSec Site Connections under a single VPN Service? I understand this creates multiple tunnels from the same OpenStack router to different remote peers. Current Issue: One of my connections shows "PENDING_CREATE" status while the other is "ACTIVE". I'm trying to determine if this is: A configuration issue on my end A limitation of having multiple tunnels per VPN service A strongSwan-specific behavior in the OpenStack context Specific Questions: Does VPNaaS officially support multiple IPSec connections per VPN Service? Are there any known limitations or best practices when using multiple tunnels? Should each remote site have its own dedicated VPN Service instead? I've checked the documentation but couldn't find clear guidance on multi-tunnel scenarios. Any insights from the community would be greatly appreciated. Environment: OpenStack version: 2024.2 Dalmatian Neutron VPNaaS with strongSwan backend Kubernetes-deployed OpenStack (OpenStack-Helm) Waiting for your reply, Thank you for your time and assistance! Best regards, Shubham

[heat][mistral][tc] Status of ply
by Takashi Kajinami 18 Sep '25

18 Sep '25

Hi, As you might know, some of the OpenStack projects, heat and mistral, use yaql to support flexible user input. The yaql library has been tiny and stable, thanks to the ply[1] library which is the python-written implementation of lex and yacc . However, it was declared that no further release of ply is planned[2] and the author now suggests copying it into the project[3]. The old released version has been working so far, but I'm unsure if it could survive through recent drastic changes in python package tooling. Looking at the code, it seems all codes are tagged with BSD 3-clause license[3] though the repository lacks the LICENSE file. I guess that the easiest approach is to import the codes to somewhere within yaql (like yaql._ply) and use the imported codes, with a note explaining these codes are imported from ply. This follows the suggestion by the author, but I'd like to get some guidance from TC to make sure it won't break the whole license expectation. An alternative approach is to implement our own parser, though I'm not too sure if that's feasible at least from my PoV. If we want this approach, then we need actual volunteer for it who will immediately start working on it. If neither of the two options above work, we might end up removing yaql functionality completely from OpenStack. AFAIK the one in heat was added for TripleO which was already retired so the impact may be limited, while for mistral removal could have lager impact. Thank you, Takashi [1] https://github.com/dabeaz/ply [2] https://github.com/dabeaz/ply?tab=readme-ov-file#important-notice---october… [3] https://github.com/dabeaz/ply?tab=readme-ov-file#questions-and-answers [4] https://github.com/dabeaz/ply/blob/master/src/ply/lex.py#L10-L33 -- Takashi Kajinami irc: tkajinam github: https://github.com/kajinamit launchpad: https://launchpad.net/~kajinamit

Putting DB/WAL on SSD on
by William Muriithi 16 Sep '25

16 Sep '25

Hello, We want to use ceph as the openstack storage system and we can afford a purely SSD based storage system. So we are planning to just setup meta data on SSD and leave the data on HDD The documentation around this isn't very clear and wonder if someone can explain a bit Here is what the documentation say:- https://docs.ceph.com/en/reef/start/hardware-recommendations DB/WAL (optional) 1x SSD partion per HDD OSD 4-5x HDD OSDs per DB/WAL SATA SSD <= 10 HDD OSDss per DB/WAL NVMe SSD What does this mean? I am sorry to say, but it look a tad ambiguous to me, but suspect its obvious once one have experience. I have 6 8TB disk per system, and I want to use replication so will end up with 18 OSD I am hoping I don't need 18 SSD as we don't even have enough bays If we can add in 2 800GB SSD per hardware, how do we optimally map those 18 DW/WAL to a total of 6 SSD disks? Regards, William

[tc][all] OpenStack Technical Committee Weekly Summary and Meeting Agenda (2025.2/R-2)
by Goutham Pacha Ravi 15 Sep '25

15 Sep '25

Hello Stackers, We're two weeks away from the date of the coordinated 2025.2 "Flamingo" release [1]. At this time, nearly all deliverables that follow the "cycle-with-rc" release model [2] have shipped their first release candidate. Over the next couple of weeks, OpenStack project teams will be expected to test, find and resolve any release blockers in these deliverables. The ongoing elections to fill four seats on the OpenStack Technical Committee and to elect a PTL for the OpenStack Dashboard ("Horizon") project team will conclude at 23:45 UTC on September 17, 2025 [3]. If you haven't already voted, please do so. There were no new governance proposals that were merged in the past week. === Weekly Meeting === The last weekly meeting of the OpenStack Technical Committee was held on September 9, 2025 [4]. We discussed project teams that had no PTL candidates in the ongoing renewal exercise: Vitrage, OpenStack Charms, Venus, and Monasca. You are all aware that we began the retirement process for the Monasca team [5] and are actively considering a maintainer request. We expect to make a decision past the 2025.2 "Flamingo" coordinated release. We have had a call for help [6][7][8] advertisement for the other projects and will discuss alternatives if those go unanswered. The TC discussed efforts to increase voter turnout for OpenStack elections by encouraging people to opt in to CIVS emails. A related topic was the reduced electorate, which was suspected to be due to OpenInfra Foundation (OIF) membership renewal requirements. The committee agreed to follow up on this after the elections conclude. We discussed default MySQL/MariaDB charset/collation changes that affect most OpenStack service projects. A few key points were discussed, including the need for a potential community goal to migrate from utf8 (which aliases to utf8mb3) to utf8mb4 due to MariaDB's plan to remove the utf8 alias. The meeting also addressed a known issue with Ironic, which has conflicts with the larger utf8mb4 type due to index size limitations. We decided to gather more data on what each project is currently using to better understand the scope of the problem. Dmitriy Robotyogev (noonedeadpunk) and Seunghun Lee (seunghunlee) volunteered to collect this information and add it to a new Etherpad [9] that will inform next steps. After the meeting, Jonathan Wright (JonathanWright[m]) from AlmaLinux joined us to discuss the potential for adding AlmaLinux to OpenStack's supported runtimes, noting its benefits like support for older CPUs (AlmaLinux 10 continues to support older CPUs like x86-64-v2) and more stable CI mirrors compared to CentOS Stream. This could be a significant benefit for OpenStack's CI (Continuous Integration) providers, as it would allow them to utilize their existing, aging hardware more effectively for testing. Community contributors from AlmaLinux want to improve its integration with OpenStack, including creating tailored cloud images for CI and contributing infrastructure resources. We agreed that a clear goal is to establish a working relationship with AlmaLinux volunteers to create and maintain CI images. This effort would likely involve a "pop-up team" to handle the initial implementation, with a long-term plan for AlmaLinux contributors to take ownership of the testing infrastructure. The primary objective is ensuring OpenStack services and deployments can be reliably tested and deployed on AlmaLinux, thereby expanding the project's supported user base. If you're interested to be a part of this effort, please chime in on the #openstack-tc channel on OFTC. The next meeting of the OpenStack Technical Committee is on Tuesday, September 16, 2025, at 1700 UTC. It will be hosted on the #openstack-tc IRC channel on OFTC. Please find the meeting's agenda on the OpenStack wiki [10]. I hope you'll be able to join us there. === Governance Proposals === ==== Open For Review ==== - Retire metalsmith project from bare metal program | https://review.opendev.org/c/openstack/governance/+/958297 - 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 - Extend Monasca's inactive state | https://review.opendev.org/c/openstack/governance/+/959392 === Upcoming Events === - 2025-09-17: OpenStack TC and Horizon project elections conclude: https://governance.openstack.org/election/ - 2025-10-01: OpenStack 2026.1 "Flamingo" release day - 2025-10-03: OpenStack's Birthday Meetup, Austin: https://www.meetup.com/openinfra-austin/events/310508680 - 2025-10-17: OpenInfra Summit, Paris-Saclay: https://summit2025.openinfra.org/ - 2025-10-27: OpenInfra PTG: https://openinfra.org/ptg/ Thank you very much for reading!

[neutron][taas][taap-as-a-service] moving client to seperate package
by Mohammed Naser 14 Sep '25

14 Sep '25

Hi there, It seems that at the moment, tap-as-a-service package contains both the server and the client components, which means that if you are trying to pull in the CLI components, you end up with Neutron as well, which is quite heavy. Is there a reason behind it that decision or is this something that someone needs to get around doing but no one has? Thanks, Mohammed

[all] No documentation for the API wsgi entry point of project APIs
by Thomas Goirand 13 Sep '25

13 Sep '25

Hi, As we're supposed to move away from uwsgi's config: wsgi-script=/usr/bin/<something> I'm switching all (-most every) Debian package to: module=<something-else> in the shipped <project>-api-uwsgi.ini file. In some case, that's fine, the release note tells where to find it. However, in a general way, it's documented nowhere but in the release note. In some cases, like for Magnum, the release note only tells that the wsgi-script is deprecated, without even telling to what I should switch. I've double-guessed that it should be: magnum.wsgi.api:application as this is what devstack/lib/magnum is doing. But I'm not sure, and I'll have to check for that fact after my package is built. Someone told me on IRC that I was right, and that this path is probably the "standard" for all projects. One shouldn't have to hunt for this kind of information. Could we agree on a *STANDARD* way to document this in every project? Or at least document somewhere OpenStack wide, that the standard path *must* be: magnum.wsgi.api:application and that distros and operators should expect it? Or is it that I missed the information and that's already documented? If that's the case, where is it? Cheers, Thomas Goirand (zigo)

[masakari]HACluster Containers Failing
by Thamanna Farhath 12 Sep '25

12 Sep '25

Hi OpenStack Community, I have installed *Masakari* using Kolla-Ansible, and after that I also installed *HACluster*. However, the HACluster containers are failing and keep exiting. Setup: - 3 controller nodes - Multiple compute nodes - Deployment: Kolla-Ansible My questions are: 1. Do I really need Masakari together with HACluster for instance HA? 2. Is there an alternative or recommended way to deploy HACluster with Kolla-Ansible? 3. Has anyone faced the issue where HACluster containers keep exiting after deployment? Any guidance, troubleshooting tips, or experiences would be very helpful Thanks, Thamanna Farhath N Disclaimer : The content of this email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to which they are addressed.

[release] Release countdown for week R-2
by Thierry Carrez 12 Sep '25

12 Sep '25

Development Focus ----------------- At this point we should have release candidates (RC1 or recent intermediary release) for (almost) all the 2025.2 "Flamingo" deliverables. Teams should be working on any release-critical bugs that would require another RC or intermediary release before the final release. Actions ------- Early in the week, the release team will be proposing stable/2025.2 branch creation for all deliverables that have not branched yet, using the latest available 2025.2 "Flamingo" release as the branch point. If your team is ready to go for creating that branch, please let us know by leaving a +1 on these patches. If you would like to wait for another release before branching, you can -1 the patch and update it later in the week with the new release you would like to use. By the end of the week the release team will merge those patches though, unless an exception is granted. Once stable/2025.2 branches are created, if a release-critical bug is detected, you will need to fix the issue in the master branch first, then backport the fix to the stable/2025.2 branch before releasing out of the stable/2025.2 branch. After all of the cycle-with-rc projects have branched we will branch devstack, grenade, and the requirements repos. This will effectively open them up for 2026.1 "Gazpacho" development, though the focus should still be on finishing up 2025.2 "Flamingo" until the final release. Opening up the new development cycle is also a good opportunity to teams to revise their zuul jobs and used nodesets and clean up all unnecessary ones. For projects with translations, watch for any translation patches coming through and merge them quickly. A new release should be produced so that translations are included in the final 2025.2 "Flamingo" release. Finally, now is a good time to finalize release notes. In particular, consider adding any relevant "prelude" content. Release notes are targeted for the downstream consumers of your project, so it would be great to include any useful information for those that are going to pick up and use or deploy the 2025.2 "Flamingo" version of your project. Upcoming Deadlines & Dates -------------------------- Final RC deadline: September 26th, 2025 (R-1 week) Final 2025.2 "Flamingo" release: October 1st, 2025 OpenInfra Summit Europe: October 17th-19th, 2025 -- Thierry Carrez (ttx)

[requirements]Flamingo pyroute2 regression
by Balazs Gibizer 12 Sep '25

12 Sep '25

Hi requirements folks, We identified a bug[1] in pyroute2 0.9.1 that causes intermittent failures during interface attach / detach operations. Originally we got the indication that the pyroute2 0.9.4 fixed the issue and our tests showed green results so we bumped to that version. But since then we observed that the problem still happens in 0.9.4 as well. Can we roll back our pyroute2 dependency to < 0.9 in Flamingo so close to the release? If not, can we later roll back the requirement on stable/2025.2? Or the only way is to roll forward on stable/2025.2 (and on master) when the fix appears in pyroute2? Thanks, gibi [1]https://bugs.launchpad.net/os-vif/+bug/2109396

[nova]Guidance on Instance Migration Issues in Production
by Thamanna Farhath 11 Sep '25

11 Sep '25

Hi All, I’m facing some issues with instance migration in production and need advice: Migrations are taking longer than expected—any tips to handle delays? When the host is fully utilized or overcommit ratio is high, migration sometimes fails with "valid host not found". Are there other common causes? Can we use a separate network interface for migration in OpenStack, and is it recommended? Any guidance or references would be appreciated.

[nova]Hypervisor Data and Overcommit Ratio via API
by Thamanna Farhath 11 Sep '25

11 Sep '25

Hi All, I noticed a mismatch between hypervisor data shown in Horizon and via the OpenStack API. The API returns original values without calculating the overcommit ratio. Could you advise how to retrieve the effective resources including overcommit ratio via the API?

[cinder]Issue Deleting Volume Snapshots in OpenStack
by Thamanna Farhath 10 Sep '25

10 Sep '25

Hi All, I’m facing an issue when deleting volume snapshots in our OpenStack environment (Kolla-Ansible + Ceph). The snapshots get stuck in error deleting status. Logs show: rbd.PermissionError: [errno 1] RBD permission error (error unprotecting snapshot b'volume-<id>'@b'snapshot-<id>') Could you suggest ways to resolve this or reduce such permission errors during snapshot deletion?

[sdk][requirements] RFE requested for openstacksdk
by Stephen Finucane 10 Sep '25

10 Sep '25

o/ Per request from elodilles, I'd like to request a Requirements Freeze Exception (RFE) for openstacksdk in order to release [1]. That resolves a minor bug that is currently preventing us bumping the minimum version of openstacksdk before we release Flamingo [2]. fwiw, 4.7.0 itself consists mainly of wholly new features, bug fixes, and test cleanup.

[cinder] IBM SVf driver callhome
by Vivek Pandey 10 Sep '25

10 Sep '25

Hi Joe/ Brian, Since we didn’t get a chance to discuss the patch [IBM SVf driver] Adding support for callhome plugin, we can continue the conversation here. Patch : https://review.opendev.org/c/openstack/cinder/+/951829. We need callhome enabled as default for which we have introduced a parameter “callhome” in cinder.conf. This feature is to fecth the os_version, cinder-manage version and ispbhaenabled. Note: We are not fetching any customer’s sensitive data. Please let me know if you’ve had a chance to review NetApp’s ActiveIQ implementation. Netapp’s ActiveIQ code ref : https://github.com/openstack/cinder/blob/master/cinder/volume/drivers/netap… As we have discussed during the 9th July cinder call, Anoop from NetApp confirmed that they are enabling it by default and EMS details are being captured from the logs. Based on that, do you think we can align or extend our current IBM callhome implementation (from the patch above) to follow a similar approach? Thanks, Vivek

OpenStack wide MariaDB 11.8 problem
by Seunghun Lee 10 Sep '25

10 Sep '25

Dear OpenStack developers I'm a Kolla contributor and was trying to bump MariaDB from 10.11 to 11.8 for Kolla and Kolla-Ansible projects. During this, I found problems that can happen across the whole OpenStack services with MariaDB's default charset and collation set changes. Here's the note I made for each problem I found. Problems with default collation set change - MariaDB changed default collation set of charset utf8mb3 from utf8mb3_general_ci to utf8mb3_uca1400_ai_ci from 11.5 https://jira.mariadb.org/browse/MDEV-25829 - K-A currently sets database level charset to utf8 (Which is aliased to utf8mb3) and collation set to utf8_general_ci (aliased to utf8mb3_general_ci) - Problem detected when deploying fresh magnum on MariaDB 11.8: https://bugs.launchpad.net/magnum/+bug/2121797 - This is because how MariaDB works. If charset is not specified when creating a table, MariaDB uses database level charset and collation set (if set) or server level charset and collation set - If only charset is specified when creating a table, MariaDB uses MariaDB default (defined as a list of mapping in variable ``collation_connection``) - Magnum specified charset when creating *some* of tables not all -> Collation set inconsistency in magnum database. - Server-wide collation set inconsistency (when DB and services are freshly deployed) - Some services such as Nova, Keystone, Cinder, designate provides charset when creating tables (Also alters database level charset to utf8 in first alembic op) Let's call them group A - Some services such as Glance, Neutron, Octavia, Placement don't. Let's call them group B - Then we have Magnum which mixed up. Let's call it... Magnum - These differences cause database level collation set inconsistency between group A and group B services because of MariaDB's behaviour on creating a table and database - Potential problem for MariaDB 10.11 to 11.8 upgrade - Existing databases in MariaDB server have collation set of utf8mb3_general_ci - Because of MariaDB's new default collation set for utf8mb3 and how the table creation works, if any services decide to create a new table, they can be created with utf8mb3_uca1400_ai_ci and causes collation set inconsistency - This issue can be invisible at first but if any project decides to create new tables then do string comparison between the old tables and new tables, it will be visible - Potential solution A: Override MariaDB default for utf8mb3 to utf8mb3_general_ci for each service clients https://mariadb.com/docs/server/reference/data-types/string-data-types/char… - Pros: Easy - Cons: - In fact, it doesn't work. Because there are slight differences on how each projects create tables, only some of them (Keystone, designate) are affected - Even if it worked, It's just delaying the problem. Looks like community pushed forward in the past: https://review.opendev.org/c/openstack/kolla-ansible/+/455154 - Potential solution B: Change K-A's server level collation set config to utf8mb3_uca1400_ai_ci then migrate (ALTER TABLE) all tables to use new collation on upgrade - Pros: We'll probably don't need to worry about this matter for a long time - Cons: - Service disruption, inter-table relationships such as foreign keys make altering table hard. - Percona-toolkit claims it can be done with near-zero downtime with FK handling strategies. Can be useful. https://docs.percona.com/percona-toolkit/pt-online-schema-change.html (GPLv2 license) - Potential solution C: Use MariaDB 11.4 instead - Pros: 11.4 is also an LTS but without this drama - Cons: Not the latest LTS Problems with default character set change - MariaDB's new default charset utf8mb4 https://jira.mariadb.org/browse/MDEV-19123 - This is not urgent but MariaDB is planning to remove alias between utf8 and utf8mb3 https://jira.mariadb.org/browse/MDEV-30041 - Currently most of openstack projects use 'utf8' when specifying a character set not 'utf8mb3'. This will all need to be updated to 'utf8mb3'. - Or we can try moving on to utf8mb4 but ironic need to use utf8mb3 due to its internal design https://docs.openstack.org/ironic/latest/install/install.html#set-up-the-da… - Transition to utf8mb4 would also need a migration plan - Using MariaDB 11.4 also helps here because this change is from 11.6 I suggest to raise this topic on next OpenStack TC meeting. I think it's worth having a inter-project conversation as these will affect any projects that uses DB. What do people think about this? Any inputs are appreciated. Kind regards, Seunghun Lee Cloud Engineer, StackHPC
