Can only live migrate between hypervisors with same kernel
by sinan86polat＠gmail.com 10 Sep '24

10 Sep '24

Is it normal behavior that instances can only be live migrated between hypervisors running the same kernel? Like this I am not able to patch my hypervisors without downtime on the instances. When I live migrate all instances from hypervisor A to hypervisor B, patch hypervisor A, I cannot migrate the instances back to hypervisor A since it is running a newer kernel. The error is: guest CPU doesn't match specification: missing features: xsaves My source and target hypervisors have both the same CPU. Running OpenStack Rocky.

Clarification on Custom Role and Sub-User Management in OpenStack
by Thamanna Farhath 10 Sep '24

10 Sep '24

Dear OpenStack Community, I hope this message finds you well. I am reaching out to seek clarification and guidance on a scenario involving custom roles and sub-user management within OpenStack. In our deployment, we have the standard admin role as well as a custom role called super_user, which grants privileges for CRUD operations on projects, role assignments, and user management. We currently have two users with the super_user role, named Alice and John. Each of these super_user accounts manages their own sub-users: Alice manages the ABC sub-users, and John manages the XYZ sub-users. I would like to implement a restriction where Alice, as a super_user, can only manage the A,B,C sub-users and should not be able to delete or manage John's X,Y,Z sub-users. Similarly, John should not be able to manage or delete Alice's A,B,C sub-users. My questions are as follows: How can I identify and ensure that ABC sub-users belong to Alice and X,Y,Z sub-users belong to John? What is the best approach to implement this restriction within OpenStack, preventing cross-management of sub-users between Alice and John? Will using the multi-domain concept help me achieve this? Any insights, best practices, or suggestions on how to configure this within OpenStack would be greatly appreciated. Thank you for your assistance and support.

[swift] Ideas: Object Locking
by David Zanetti 10 Sep '24

10 Sep '24

Hello everyone! We've added an entry to the Swift ideas page about implementing Object Locks. The full description of what this would be and how we expect it to work is in the ideas page here: https://wiki.openstack.org/wiki/Swift/ideas/object-lock I have two questions of the community. The first is whether work on this would be accepted by the Swift project, as we wouldn't want to expend efforts on something we'd have to carry as our own patches to upstream. The second is if there is any interest from other people to collaborate on design/implementation of the locking feature. Happy to take replies off-list if people prefer, and thanks for reading this far! (Ob-reply: Yes, we know Ceph RGW does this already. We use Swift for Object for $REASONS, which we'd like to keep doing.) -- David Zanetti Chief Technology Officer [1]Aotearoa New Zealand's cloud provider e david.zanetti(a)catalystcloud.nz w catalystcloud.nz Follow us on LinkedIn [2] Level 9, 33 Federal Street, Auckland 1010 [1] https://catalystcloud.nz/ [2] Follow us on LinkedIn https://www.linkedin.com/company/catalyst-cloud-limited/

[tc][all] OpenStack Technical Committee Weekly Summary and Meeting Agenda (2024.2/R-3)
by Goutham Pacha Ravi 10 Sep '24

10 Sep '24

Hello Stackers, Projects following a cycle-with-rc release model are hard at work alongside the release team to tag the first version of the 2024.2 release candidates (RC) this week [1]. The community would appreciate testing of these RC builds so we can weed out any critical issues prior to the coordinated release of this software in three weeks (2024-10-04). The OpenStack Technical Committee Election is ongoing. If you are a Foundation Individual Member who has been an Active Contributor during the past year, you should have received an email ballot with the details. If you haven't, please pop into #openstack-election and let us know. I hope you'll be able to make your vote count. === Weekly Meeting === The OpenStack Technical Committee met simultaneously over video [2] and IRC [3] last week. We took note of the smooth kick-off to the community elections and appreciated the effort the election officials have put in thus far. With the retirement of several inactive project teams and some focused outreach, we had far fewer projects without PTL candidates this time [4]. I will keep you posted on the TC's course of action in this matter over the next few weeks. At the meeting, we brainstormed reasons why these project teams had no PTL candidates, and whether Distributed Project Leadership is an appropriate choice for relatively stable project teams. We reflected on the community's experience with leadership appointments in the past where the appointed individuals couldn't sustain the project. These past experiences will help shape the TC's decisions. We noted that the maintenance phase transition for the stable/2023.1 ("Antelope") branch is coming up. The release team estimates transitioning the "stable/2023.1" branch across OpenStack repositories to "unmaintained/2023.1" [5] around 2024-10-30. After this transition, no further releases will be produced from these branches. If you are relying on this branch, please help project teams maintain testing and continuous integration for it. However, note that the release would be 19 months old at the time of this transition; consider upgrading the software to newer releases instead. The TC is considering a change to the OpenStack CI policy of re-enqueuing changes through Zuul when approved patches fail to get merged. Currently, if a change that fails "gate" jobs is re-enqueued, "check" jobs are re-run if new changes are detected in the repository. A suggestion was made to alter this policy so that only the "gate" jobs are repeated. We decided to defer this discussion to the upcoming PTG in October. We concluded the meeting by acknowledging the contributions Jay Faulkner (JayF) and Dan Smith (dansmith) made during their time on the TC. The elections will conclude on 2024-09-18. Again, please vote if you haven't already! :) The next meeting of the OpenStack Technical Committee is today: 2024-09-10. It will be hosted on OFTC's #openstack-tc channel at 1800 UTC. Please find the agenda on the meeting's wiki page [6]. I hope you'll be able to join. Please remember that you can propose discussion items to the agenda. === Governance Proposals === ==== Merged ==== - Fix typo in tested runtimes documents | https://review.opendev.org/c/openstack/governance/+/928603 ==== Open for review ==== - Add goal to migrate CI/CD jobs to Ubuntu Noble | https://review.opendev.org/c/openstack/governance/+/928078 - Adding Axel Vanzaghi as PTL for Mistral | https://review.opendev.org/c/openstack/governance/+/927962 - Charms: retire unmaintained charms | https://review.opendev.org/c/openstack/governance/+/926793 - Retire all single charm repositories | https://review.opendev.org/c/openstack/governance/+/903490 - Retire kuryr-kubernetes and kuryr-tempest-plugin | https://review.opendev.org/c/openstack/governance/+/922507 === Upcoming Events === - 2024-09-10: OpenInfra Board Meeting: https://board.openinfra.dev/ - 2024-09-18: OpenStack 2025.1 Election Polling Ends - 2024-10-15: OpenInfra Days NA, Indianapolis: https://ittraining.iu.edu/explore-topics/titles/oid-iu/ - 2024-10-21: OpenInfra Project Teams Gathering https://openinfra.dev/ptg/ === How to Contact the TC === You can reach out to the TC in multiple ways: 1. **Email**: Send an email with the tag [tc] on this email list. 2. **IRC**: Ping us using the 'tc-members' keyword on the #openstack-tc IRC channel. 3. **Weekly Meeting**: The Technical Committee meets every week on Tuesdays at 1800 UTC [6].

[nova][ci] cyborg-tempest (non-voting) job is failing
by melanie witt 10 Sep '24

10 Sep '24

Hey everyone, I noticed that the cyborg-tempest (non-voting) CI job began failing on the master branch sometime on 2024-09-03: https://zuul.opendev.org/t/openstack/builds?job_name=cyborg-tempest&project… The errors I see in the test result report are policy related, for example: Details: {'error_message': '{"faultcode": "Server", "faultstring": "\\"cyborg:device_profile:create\\": \\"rule:system_admin_api\\" requires a scope of [\'system\'], request was made with project scope.", "debuginfo": null}'} I'm guessing this is related to the recent "oslo.policy 4.4.0 enable the RBAC new defaults by default" change [1]: https://review.opendev.org/c/openstack/requirements/+/925464 The job is non-voting so it's not blocking anything, but it would be great if someone knows the best way to fix it. -melwitt [1] https://lists.openstack.org/archives/list/openstack-discuss@lists.openstack…

Using diskimage-creator for vhd format
by Tony Lombardo 06 Sep '24

06 Sep '24

Hi all. As an example I was trying to run something like this command: sudo tox -e venv -- disk-image-create -o ubuntu-min-gold.vhd vm block-device-gpt ubuntu-minimal -t vhd However, I do get the error message that vhd-util isn't available. "vhd output format specified but no vhd-util executable found." I read the commit where this was deprecated in favor of qemu-img https://opendev.org/openstack/diskimage-builder/commit/a3e9e7f89e1059ae0929… I can't seem to get the syntax for the command to work, not sure what I am missing but any help would be greatly appreciated. QEMU emulator version 6.2.0 Diskimage-builder 3.33.1 I'm running this in WSL Ubuntu, it seems to work. I was able to create an image - just not the vhd format I need. Thanks in advance for any advice. -Tony -- Tony Lombardo Systems Administrator Division of Public Safety Access Control Department Cornell University

Struggling to rejion a node into rabbitmq cluster of Openstack-on-Ansible environment
by sudeb ghosh 06 Sep '24

06 Sep '24

Hi Team, We are operating an OpenStack environment managed by Ansible with 3 controller nodes. Openstack Version: Ussuri(21.2.1) OS: CentOS8 Recently, Controller-2 encountered a network partition with rabbitmq cluster issue that we couldn't resolve, leading us to remove it from the rabbitmq cluster and do rabbitmqctl reset. Since then, the RabbitMQ cluster node removal, We are currently unable to rejoin this node to the RabbitMQ cluster. The following error occurs when attempting to join the cluster: [Controller-2]# rabbitmqctl join_cluster rabbit@ctrl-1-rabbit-mq-container Clustering node rabbit@ctrl-2 with rabbit@ctrl-1 Error: {:failed_to_cluster_with, [:"rabbit@ctrl-3", :"rabbit@ctrl-1"], 'Mnesia could not connect to any nodes.'} We have verified that Controller-2 can communicate with other nodes in the cluster and it responds with a 'pong' for "rabbitmqctl eval 'net_adm:ping('\''rrabbit@ctrl-1'\'').'" There are no additional error logs indicating the root of the problem. We would appreciate any assistance in resolving this issue. Regards, Sudeb Ghosh 7044064878 9332034788
