openstack server create fails with: Invalid PCI alias definition: Expecting property name enclosed in double quotes
by Sigurd Kristian Brinch 20 Nov '25

20 Nov '25

When I try to create a VM with: openstack server create and the flavor has a property set with "pci_passthrough:alias"="NVIDIA-H200-35C:1" The error message is: novaclient.exceptions.BadRequest: Invalid PCI alias definition: Expecting property name enclosed in double quotes: line 1 column 29 (char 28) (HTTP 400) (Request-ID: req-66fb38d8-8f49-4073-99a2-fa4677d9b48e) Anyone have any idea what is causing this? A similar command worked fine just last week. Attached is the debug output from the create command BR Sigurd

[horizon] Considering a change in how SCSS styles are handled
by Radomir Dopieralski 19 Nov '25

19 Nov '25

Hello everyone, while working on some other part of Horizon, I recently looked at the source of the pages generated, and noticed that a substantial amount of each page is the style, compiled and included on every single page using the <style> tags. That is a rather bad practice for a number of reasons, from performance to waste of bandwidth. I decided to see if that could be easily fixed, so prepared this patch that instead includes the compiled style using a <link> tag: https://review.opendev.org/c/openstack/horizon/+/966665 Now, I'm writing to this list for two reasons. The first is to make sure that there isn't some rule or regulation, possibly introduced before the Web was invented, that requires all OpenStack software to handle the styles in that way, and that we would be breaking if we went with my patch. The second is of a more technical nature, and pertains to the change that had to be made to the `_components.scss` file in that patch. In short, a similar change would have to be done in any Horizon plugin that adds style sheets to `HORIZON_CONFIG.scss_files`. Since we don't have control over Horizon plugins and can't possibly force such a change, and since merging my patch without such changes would break the plugins, I would like to hear from the plugin maintainers about the best way to proceed with this (or, just leaving things as they are, if that is the better option). The change becomes necessary, because the included `scss_files` can no longer be compiled in one huge block with the rest of horizon's styles, but have to be included with their own <link> tags as separate files, which means that any dependencies they rely on have to be explicitly included using the `@import` mechanism. Most of those styles at the minimum will rely on the common variables from the theme, that's why this particular import, but there may be a need for more imports added depending on what the stylesheet in question uses. I'm also open to suggestions on how to avoid the need for this change and compile everything in one big blob as we are doing now, but don't inline the style on every page. Between Django, Django-compressor, SCSS compiler and template mechanism, I don't currently see a way to do this. Thank you for your feedback, -- Radomir Dopieralski

[eventlet-removal][Neutron] neutron-dynamic-routing project status
by Rodolfo Alonso Hernandez 19 Nov '25

19 Nov '25

Hello all: Since [1], Neutron removed any dependency of "eventlet", including several auxiliary methods used by other projects, in particular neutron-dynamic-routing. We have been trying to clean-up this project, updating the requirements (removing eventlet, updating os-ken) and refactoring the DR agent classes (similar to what was done in the DHCP or L3 agents). But the DR agent is still failing [2], maybe due to an incorrect implementation in os-ken. However, due to the limited time we have, we cannot investigate it. *This email is a request for assistance in getting the users/developers of that project to remediate the code and remove the eventlet dependency.* This topic and the resolution taken was mentioned in the last Neutron meeting [3]. Regards. [1]https://review.opendev.org/c/openstack/neutron/+/961210 [2]https://review.opendev.org/c/openstack/neutron-dynamic-routing/+/956747 [3] https://meetings.opendev.org/meetings/networking/2025/networking.2025-11-18…

[2023.1][kolla][rabbitmq] Failing to get packages from RabbitMQ Repos
by Rob Jefferson 18 Nov '25

18 Nov '25

Folks, At work, we're using Kolla 2023.1, and during a recent build, I saw that the PPA that provided RabbitMQ packages gave me a "402 Payment Required" error. This seems to be an existing problem, so I decided to try using the PPA that's in the current version of 2023.1 Kolla. When I change the repo in `kolla/templates/repos.yml` so that the URL is https://ppa1.rabbitmq.com/rabbitmq/rabbitmq-server/deb/ubuntu and the key in `docker/base/Dockerfile.j2` to be 9F4587F226208342, I get the following error: > E: The repository 'https://ppa1.rabbitmq.com/rabbitmq/rabbitmq-server/deb/ubuntu jammy Release' does not have a Release file. If, on the other hand, I use the PPA in the official RabbitMQ docs: https://deb1.rabbitmq.com/rabbitmq-erlang/ubuntu/jammy And use the key 0A9AF2115F4687BD29803A206B73A36E6026DFCA, I get the following error: > W: GPG error: https://deb1.rabbitmq.com/rabbitmq-server/ubuntu/jammy jammy InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 6B73A36E6026DFCA > INFO:kolla.common.utils.rabbitmq:E: The repository 'https://deb1.rabbitmq.com/rabbitmq-server/ubuntu/jammy jammy InRelease' is not signed. In both cases, I'm not sure what the issue is. I would have expected RabbitMQ server for Jammy to still be available in the first case (especially since that PPA remains in Kolla), or for the key I used in the second case to exist. Is there something I can try to fix this issue? Thanks, Rob

Updating Monitor List (rbd section) using Virsh with no downtime
by m.riudalbas＠first-colo.net 18 Nov '25

18 Nov '25

Hello, is there a way to update a monitor list of the rbd section in a virtual machine? We need to add or modify the following entries. <source protocol='rbd' name='cinder/volume-343766ad-0086-4f8c-a557-bc60ba2210f4' index='1'> <host name='172.16.65.164' port='6789'/> <host name='172.16.65.165' port='6789'/> <host name='172.16.65.166' port='6789'/> </source> We want to replace the Monitor network and this means that we have to update every virtual machine with the new Ceph monitor IPs. The only way to replace them is with a live migration (then the live ceph configuration with the new IPs will be applied), but we would like to know if there is a faster way (because we have approximately 200-300 VMs) and some of them are so big that a live migration is impossible (only an offline migration could be done, resulting in a downtime). Another way to refresh the list is detaching the volume, but this only works for non-bootable volumes. We tried modifying the virsh XML directly (virsh edit ...) and creating a separate XML file and applying it with "virsh define newfile.xml", but the list will not be updated. Many thanks in advance!

Hi there Kees! Thank you for checking; I wanted to bounce my response to the list because others may be in a similar situation of wanting to make Chair or documentation updates to the SIGs docs in the TC repo. Any contributor can propose changes to the SIG docs that are maintained here: https://opendev.org/openstack/governance/src/branch/master/reference/sigs In your case, you'd fix up the "chairs" and "status" for the Public Cloud SIG in https://opendev.org/openstack/governance/src/branch/master/reference/sigs/s… and submit your change through the OpenDev Gerrit. There is a bunch of one-time setup that's documented here: https://docs.openstack.org/contributors/code-and-documentation/quick-start.….

[qa][ops] Light-weight guest image for UEFI boot and secure boot
by Takashi Kajinami 18 Nov '25

18 Nov '25

Hi, I've been trying to implement a few tempest tests to verify functionality of UEFI boot and secure boot, and I noticed that cirros, which is used as a primary guest image for tests, do not support UEFI boot. I'm wondering if anyone can share a good light-weight guest image used in their own tests of these features ? I guess that ubuntu guest image might be a primary choice (given the fact that ubuntu is the default operating system for tests) but I'm wondering if we have more light-weight one. Thank you, Takashi -- Takashi Kajinami irc: tkajinam github: https://github.com/kajinamit launchpad: https://launchpad.net/~kajinamit
