[Cinder] pbm configuring multipath on NVMeoF
by Vincent Godin 30 Jul '25

30 Jul '25

Hello guys, Openstack: 2025.1 OS: Ubuntu 24.04 We are having trouble configuring multipath on a NetApp backend using NVMe over TCP. After reading numerous articles on this issue, we concluded that it was necessary to operate in native multipath mode, which is enabled by default on Ubuntu 24.04, and that it is no longer necessary to keep the multipathd service active for this to work. We ran inconclusive tests by setting the "use_multipath_for_image_xfer" and "enforce_multipath_for_image_xfer" variables to true in cinder.conf. We also set the "volume_use_multipath variable" to true in the libvirt section of nova.conf, but without success. After creating an instance and a volume on a server with Openstack, when querying the subsystem with the nvme command, we only get a single path. But when we query the backend from the same server with "nvme discover," we do get four paths. In the os-brick code, we see that it checks a Multipath variable that must be set to true... I think this is purely a configuration issue, but the examples given by various manufacturers (NetApp, PureStorage, etc.) don't indicate anything in particular. So, does anyone know the configuration to apply for multipath to work (cinder/nova)? Thank you.

OpenStack for AI Whitepaper
by Kendall Nelson 30 Jul '25

30 Jul '25

Hello Folks! As you might have heard, the OpenInfra AI WG has been starting to put together an OpenStack for AI Whitepaper and we wanted to formally invite you all to attend the WG's meetings and working sessions, to get involved on working group's the mailing list <https://lists.openinfra.org/mailman3/lists/ai-openstack-wg.lists.openinfra.…> and to help us shape the whitepaper into a resource for those looking to understand just how OpenStack is capable of serving AI workloads. We could really benefit from your innate understanding of how the OpenStack services work and also hope to surface feedback and questions from the group for the larger OpenStack community in future meetings. Also, we have organizations volunteering to do show and tell sessions about their OpenStack clouds hosting AI workloads and discussing pain points, lessons learned etc. The next of those show and tell sessions will take place on September 29. We have a meeting coming this week on Thursday at 13 UTC in this google meet <http://meet.google.com/wzn-jgcn-cfj>. If you would like an actual calendar invite, please reach out and I will make sure you are added! -- Kendall Nelson *Senior Upstream Developer Advocate* The OpenInfra Foundation <https://openinfra.dev/>

[tc][all] OpenStack Technical Committee Weekly Summary and Meeting Agenda (2025.2/R-9)
by Goutham Pacha Ravi 29 Jul '25

29 Jul '25

Hello Stackers, We're a month away from the feature freeze date for the 2025.2 ("Flamingo") release cycle [1], scheduled for 2025-08-28. OpenStack project teams are observing various internal deadlines prior to that important date to ensure a complete and timely release. As we look ahead, OpenStack's election officials will begin accepting self-nominations for the upcoming Project Team Lead roles and four seats on the OpenStack Technical Committee starting 2025-08-06 [2]. The nomination deadline is two weeks later, on 2025-08-20. You are welcome to submit an early nomination [3] now if you anticipate being away during the nomination window. To be a Project Team Lead candidate, you must be an Active Project Contributor—i.e., someone who has contributed to the project you wish to lead in the past 12 months (counted up to 2025-08-20). Any individual member of the OpenInfra Foundation, regardless of contributor status, may propose their candidacy for the OpenStack Technical Committee. To vote in these elections, you must be a member of the OpenInfra Foundation [4] and an active contributor—either through merged contributions to official projects or via nomination by a project’s PTL, liaisons, any Special Interest Group, or the OpenStack Technical Committee [5]. To receive your ballot, please ensure your email address is added in Gerrit and that you've opted in to receive emails from CIVS before 2025-08-20: https://civs1.civs.us/cgi-bin/opt_in.pl In the past week, the TC approved revised milestones for the cross-project goal of removing the use of Eventlet [6]. We still aim to drop Eventlet usage completely in the 2027.2 ("J") release. The "aetos" project now has a canonical service type called "metric-storage" [7]. Several other governance changes are currently under community review. === Weekly Meeting === The last weekly meeting of the OpenStack TC took place [8] on 2025-07-22, with a smaller attendance than usual. We expect this trend to continue through the summer break in the northern hemisphere. Key updates included changes to the Eventlet-removal goal timeline and a deeper look into the prolonged inactivity of the Monasca project team. While volunteers have consistently expressed interest in maintaining the project, it hasn’t met reactivation milestones since its last active cycle (2024.1). However, some improvements have been merged across the team’s repositories. The TC agreed to enforce a more formal and transparent process: projects must explicitly request extensions to inactive status [9], and future documentation will include retirement deadlines that compel TC votes on any extensions. We'll continue discussing the next steps for Monasca through governance proposals and this mailing list. Opendev administrators informed us that they completed the transition off Nodepool, and Debian Trixie images are nearly ready for testing. This is also useful for transitioning the Ceph CI job to Debian to enable faster fixes in the client software. In open discussion, the group revisited the definition of corporate affiliation in the TC charter. A proposal will be made to clarify what affiliation diversity means and how/why it should be disclosed during elections. The next meeting of the OpenStack Technical Committee is today, 2025-07-29. It will be hosted on the #openstack-tc channel on OFTC at 1700 UTC. Please find the meeting's agenda and other details on its wiki page [10]. I hope you'll be able to join us. === Governance Proposals === === Merged === - Make Eventlet removal deadlines more acceptable for operators | https://review.opendev.org/c/openstack/governance/+/952903 - Retire networking-midonet | https://review.opendev.org/c/openstack/governance/+/955364 === Open for review === - Define "affiliation" within the context of the TC | https://review.opendev.org/c/openstack/governance/+/956024 - Add series names to runtimes doc | https://review.opendev.org/c/openstack/governance/+/955810 - Remove Monasca from active project | https://review.opendev.org/c/openstack/governance/+/953671 - os-test-images never releases | https://review.opendev.org/c/openstack/governance/+/954249 - Require declaration of affiliation from TC Candidates | https://review.opendev.org/c/openstack/governance/+/949432 === Upcoming Events === - 2025-08-06: Nominations open for OpenStack elections: https://governance.openstack.org/election/ - 2025-08-20: Nominations close for OpenStack elections - 2025-08-26: OpenInfra Days, Korea: https://2025.openinfradays.kr/ - 2025-08-28: Feature Freeze deadline, Milestone-3 of the Flamingo release [1] - 2025-08-29: Colombia OpenInfra User Group Meetup: https://www.meetup.com/colombia-openinfra-user-group/events/307096751/ - 2025-10-17: OpenInfra Summit, Paris-Saclay: https://summit2025.openinfra.org/ Thank you very much for reading!

[i18n] Sharing CMU Students’ Contributions: Progress on Zanata-to-Weblate Migration
by Ian Y. Choi 28 Jul '25

28 Jul '25

Dear OpenStack Community, Over the past six weeks, Seongsoo and I had the privilege of mentoring a group of four students from Carnegie Mellon University (CMU) [1] as part of our ongoing effort to migrate the OpenStack Internationalization (I18n) platform from Zanata to Weblate. I would like to take this opportunity to highlight the significant and meaningful contributions made by three students, Furqan Saeed, Simon Yu, and Jana Hussien, who recently completed video demos showcasing their work [2] [3]. Project Context As many may know, the I18n SIG has been working to modernize our translation infrastructure by transitioning from Zanata (now unmaintained) to Weblate — an actively developed, open source platform. This project not only ensures the sustainability of our translations, but also offers a valuable learning path for new contributors. Below are the key outcomes achieved by Furqan, Simon and Jana: 1. i18n tools script test codes for Weblate (by Furqan Saeed & Simon Yu) Furqan and Simon focused on bringing robust, production-quality unit testing to the collection of Python scripts and tools responsible for Weblate integration. Furqan’s video [2] demonstrates these efforts. Together, they: Developed a comprehensive suite of ~34 unit tests covering the main Weblate tool files. Used Python’s unittest and mocking strategies to ensure functions behave as expected, even simulating server responses. Noted and addressed gaps in requirements, such as missing library dependencies. Provided clear documentation (README.rst) explaining test infrastructure and file structure. Gained and demonstrated familiarity with OpenStack’s development guidelines, Gerrit workflows, and CI requirements. Their efforts establish a much needed test baseline for future improvements and bring our I18n tooling closer to OpenStack’s best practices. This contribution not only enhances software reliability but also creates a safer, more efficient environment for future contributors. 2. Migration of Zuul infrastructure scripts to Weblate (by Jana Hussien) Jana concentrated on migrating and refactoring the automation scripts that enable daily translation updates in Zuul, shifting from Zanata to Weblate. Her work involved: Analyzing and translating the logic in current scripts to ensure seamless migration, including first-time migration routines for new projects. Developing new scripts to automate creation of Weblate components and upload of translation templates (POT) and PO files; handling language code transformations between platforms. Troubleshooting integration challenges between Weblate’s API/CLI and OpenStack workflows, identifying and overcoming tricky configuration issues related to version control structure. Successfully demonstrating the migration workflow for projects such as trove-dashboard and horizon, with detailed documentation of results. Improving operational resilience by implementing enhanced error handling and summary reporting in the scripts. Discovering and addressing several issues during live testing, and documenting workarounds and plans for future improvements. Jana has also outlined next steps, including integrating these scripts further into the Zuul pipeline, modularizing code, and enhancing public documentation. These contributions represent valuable progress toward a full, sustainable migration to Weblate - benefiting the entire OpenStack community by advancing our translation workflows and broadening global accessibility. On behalf of all mentors (myself, Seongsoo Cho, Goutham Pacha Ravi), I’d like to thank Furqan, Simon, and Jana for their hard work, dedication, and collaborative spirit, and encourage other students and new contributors to get involved. If anyone would like to review their code, documentation, or get involved in this effort, please feel free to reach out or interact directly with their contributions [6-9]! Best regards, Ian Y.

[Kolla-ansible][epoxy]nova problems at restart
by Franck VEDEL (UGA) 25 Jul '25

25 Jul '25

Hello everyone, I need your help. II will try to explain my problem by providing a lot of information. I have been trying to solve it for 3 days, without success. In May, my old cluster became too small for the 200 students using it, so I started installing a new cluster. Six nodes, three in one data center, three in another. After testing with Bobcat and Caracal (unsatisfactory, with numerous issues, especially with authentication and display in Horizon), I tried Epoxy. I installed everything I needed and tested it. It was a real success. It was very fast in its new configuration, and I thought everything would be ready by September. In May, my old cluster was becoming too small for the 200 students using it, so I started installing a new cluster. 6 nodes, 3 in one data center, 3 in another. After testing with Bobcat and Caracal (unsatisfactory, with numerous issues, especially with authentication and display in Horizon), I tried Epoxy. I installed everything I needed and tested it. It was a real success. It was very fast in its new configuration; I thought everything would be ready by September. At the beginning of July, I was told to shut down everything, due to electrical maintenance in a data center. I shut everything down. 3 days later, I restarted it, and nothing worked anymore. However, it was simply a shutdown/restart of the servers. The problems are with Nova. Here's some information and logs, if you can help me restart the cluster. So Epoxy on Ubuntu 2404.

[neutron]instances can see traffic of others
by Nguyễn Hữu Khôi 25 Jul '25

25 Jul '25

Hello, I have some instances in the same vlan and compute node. They can see traffic from another instance which looks like port mirror. I can workaround via anti affinity rules but is there any solution for this problem? On vmware we can turn off or on promiscuous mode on the network port group. Thank you. Regards Nguyen Huu Khoi

[kolla][barbican] How to securely manage OpenStack service passwords with Castellan?
by elnaz cl 24 Jul '25

24 Jul '25

Hi all, I have deployed OpenStack using Kolla Ansible. By default, service passwords (e.g., for MySQL, Keystone, etc.) are stored in clear text inside configuration files rendered by Kolla (such as nova.conf, keystone.conf, etc.). I'm looking for a more secure approach to avoid exposing these secrets. Specifically, is there a way to integrate Barbican and Castellan with Kolla-based deployments, so that secrets can be securely loaded at runtime using oslo.config (e.g., using {{ secret:UUID }})? If this is not natively supported, are there any best practices or workarounds for handling this securely? Thanks in advance for any guidance. Best, [Your Name]

Neutron dhcp
by engineer2024 23 Jul '25

23 Jul '25

Hi Folks, In a neutron DHCP network, the route to the link local metadata ip from a VM, is thru the ip set by the neutron dhcp agent's static route option for that subnet. This is the same IP as that of the qdhcp namespace's tap interface. Can we choose a specific ip from this subnet and pass it to neutron to use the same when assigning the ip in qdhcp ns and as a static route option to link local ?

[cinder] Disable Availability Zone
by Kees Meijs | Nefos 22 Jul '25

22 Jul '25

Hello Stackers, For legacy purposes, we've got an Availability Zone running that's not to be used for new workload any more. Within Nova one could simply disable Compute Nodes (and that's what we did) ensuring no Compute Instances get scheduled. But, how about Cinder? How can we keep current workload running within a certain AZ, but ensure no new workload gets accepted? Thanks! Cheers, Kees

[tc][all] OpenStack Technical Committee Weekly Summary and Meeting Agenda (2025.2/R-10)
by Goutham Pacha Ravi 22 Jul '25

22 Jul '25

Hello Stackers, We're ten weeks away from the coordinated release of OpenStack 2025.2 ("Flamingo") [1]. The feature freeze date for this release is in five weeks (2025-08-28). In the past week, the OpenStack Technical Committee did not merge any new governance changes, though a few are currently under community review. === Weekly Meeting === The last weekly meeting of the OpenStack Technical Committee took place on 2025-07-15 over IRC [2]. The TC caught up on a backlog of action items, starting with progress on the community goal to drop the use of eventlet [3]. We discussed the activity within the Monasca project team and have reached out to the PTL and core reviewers to talk about its future. The rest of the meeting focused on the maintenance of the "service-types-authority" repository. While some suggested involving the openstacksdk-core team in its maintenance, others opined that the repo should remain under TC oversight due to its governance significance—since changes affect how services are named and recognized across the ecosystem. For now, we have renewed our commitment to reviewing and merging change proposals more actively. A late tangent about the First Contact SIG’s dormancy prompted an idea to review SIG activity at the upcoming PTG in October. The next meeting of the OpenStack TC is today, 2025-07-22, at 1700 UTC. This meeting will be hosted over IRC on the #openstack-tc channel on OFTC. The agenda has been added to the meeting's wiki page [4]. I hope you'll be able to join us there. Any community member is welcome to edit the wiki page and propose new topics. === Governance Proposals === ==== Open for review ==== - os-test-images never releases | https://review.opendev.org/c/openstack/governance/+/954249 - Retire networking-midonet | https://review.opendev.org/c/openstack/governance/+/955364 - Remove Monasca from active project | https://review.opendev.org/c/openstack/governance/+/953671 - Make Eventlet removal deadlines more acceptable for operators | https://review.opendev.org/c/openstack/governance/+/952903 - Require declaration of affiliation from TC Candidates | https://review.opendev.org/c/openstack/governance/+/949432 === Upcoming Events === - 2025-07-26: OpenInfra Days, Vietnam: https://www.vietopeninfra.org/void2025 - 2025-08-06: Nominations open for OpenStack elections: https://governance.openstack.org/election/ - 2025-08-26: OpenInfra Days, Korea: https://2025.openinfradays.kr/ - 2025-08-29: Colombia OpenInfra User Group Meetup: https://www.meetup.com/colombia-openinfra-user-group/events/307096751/ - 2025-10-17: OpenInfra Summit, Paris-Saclay: https://summit2025.openinfra.org/ Thank you very much for reading!

Instance Freeze During Snapshot in OpenStack 2024.1 with Ceph Octopus
by mohammad kokabi 21 Jul '25

21 Jul '25

Hello, I hope this message finds you well. I am currently using OpenStack version 2024.1, with Ceph Octopus as the backend storage. The configuration is as follows: Glance is configured to use the "images" pool on Ceph. The virtual machine disks are stored on the "vms" pool. When I attempt to create a snapshot of a running instance, the instance appears to freeze for a few seconds, during which it loses network connectivity (e.g., I cannot ping it). This behavior is unexpected, as I understand that snapshot operations, especially with Ceph backend, should not significantly interrupt the instance's runtime. Could you please advise what might be causing this issue? Are there any known limitations, configurations, or best practices I should be aware of regarding snapshot behavior with Ceph in this version of OpenStack? Looking forward to your insights. Best regards,

RE: Create image error
by berndbausch＠gmail.com 21 Jul '25

21 Jul '25

Violating limits imposed by the operator should lead to a useful error message rather than an HTTP 5xx error. In any case, there should have been a message in the Glance API log. Perhaps you are using a prerelease version of OpenStack? When you get Devstack from the Git, you may want to specify the version; otherwise, you obtain software that is currently under development. For example, the following gets you the first version released this year (Epoxy): git clone https://opendev.org/openstack/devstack -b stable/2025.1 ------------------------------------------------------------------------------------------------------------------- From: BEDDA Fadhel <fadhel.bedda(a)gmail.com> Sent: Saturday, May 31, 2025 6:00 PM To: berndbausch(a)gmail.com Subject: Re: Create image error Hello, I was able to work around the problem by disabling the limits in the file: /etc/glance/glance-api.conf False instead of True Thanks Le sam. 31 mai 2025 à 09:55, <mailto:berndbausch@gmail.com> a écrit : My guess is that the image service is down.

[kolla-ansible][proxysql] "Wait for backup proxysql container to start" fails
by Bursztynowski Dariusz 20 Jul '25

20 Jul '25

Hello OpenStack community, Installing Kolla-ansible OpenStack 2025.1, I've met a problem with proxysql which does not start (in task [loadbalancer : Wait for backup proxysql to start]) because of unsupported system page size: sudo cat /var/log/kolla/proxysql/proxysql.log <jemalloc>: Unsupported system page size <jemalloc>: Error in malloc(): out of memory I'm working with aarch64 CPU (Raspberry Pi 5 cluster, instructive tool for educational purposes). I have posted the bug here including more detailed description: https://bugs.launchpad.net/kolla-ansible/+bug/2117309 . What is interesting, version 2023.1 works just fine on the same HW/OS platform. I would be grateful for any suggestions on how to resolve this. Best, Dariusz Bursztynowski

[Nova] Unable to fetch CPU/RAM allocation ratios via /os-hypervisors API (Nova API v2.91 vs v2.1 support)
by Thamanna Farhath 19 Jul '25

19 Jul '25

Hello OpenStack community, I'm working with OpenStack (2023.1 kolla ansible) Nova and using the /os-hypervisors API to gather hypervisor information. I noticed that the CPU and RAM allocation ratios (which are shown in the Horizon dashboard) are not included in the response from: GET /os-hypervisors GET /os-hypervisors/{id} We're currently using Nova API version 2.91, but I see that the /os-hypervisors API appears to support only up to version 2.1, I’d like to clarify the following points: Is it expected behavior that the /os-hypervisors API does not return CPU and RAM allocation ratios? Is there any API endpoint that exposes these ratios programmatically? As we are using Nova API version 2.91, but /os-hypervisors seems limited to v2.1, is this a known limitation or design choice? If the only source of truth is the nova.conf configuration file (e.g., cpu_allocation_ratio, ram_allocation_ratio), is there any plan to expose this via API in future releases? It would be helpful to know if this is something we should work around by manually collecting config values, or if there's a more appropriate method in modern Nova setups.
