[all][tc] Eventlet migration: Call to action
by Jay Faulkner 07 Jun '24

07 Jun '24

Hi all, As you may have read in Goutham's TC summary, the existing eventlet goal[0] is unlikely to gain consensus to merge. This appears to be due to the difference in needs between OpenStack projects, and belief that it's unlikely a single solution would serve them all. Our current situation is: 1) Eventlet usage must be discontinued. The temporary maintainers are just that -- temporary -- and we should not expect eventlet to continue to be a valid path moving forward. 2) We have basic agreement that shared tooling, such as oslo libraries, should not dictate a specific threading model. In lieu of specific technical leadership and guidance from the TC, this leaves it to individual projects to decide what threading model to use instead of eventlet monkey patching. The unmerged spec[0] may be a good starting point if you're wondering where to start. Importantly: do not let this work wait! It is a significant change and will take a long time to complete. Thanks, Jay Faulkner 0: https://review.opendev.org/c/openstack/governance/+/902585

Antelope Barbican/Keystone: failure to delete secrets (Keystone TrustNotFound)
by Michel Jouvin 05 Jun '24

05 Jun '24

Hi, I've been validating Yoga -> Antelope on our preprod cloud. It was working successfully but "suddenly" (i.e. without a kwown/identified change!) when deleting Magnum clusters, the deletion of Barbican secrets (after stack deletion) fail. In the Magnum log, I find the following error: ---- Failed to delete trust: keystoneauth1.exceptions.http.Unauthorized: The request you have made requires authentication.

In particular, when the trust should be created and whether I should find somewhere a matching error at the time of the trust creation. It seems the error is only affecting deletion but I may be wrong. for the record, when starting Magnum there is an error complaining about /etc/magnum/keystone_auth_default_policy.json being not found but ignored it so far.

Antelope Magnum: creating a new cluster makes the/some others unhealthy
by Michel Jouvin 05 Jun '24

05 Jun '24

Hi, I have been playing with Magnum (Antelope), creating a lot of clusters with the same template and varying the number of masters and/or nodes, having ~10 clusters started in the same project. I observed recently that cluster configuration that used to work well were not working any more (CREATE_FAILED during the master deployment in general). I have not found any evidence of the cause digging in various logs but I observed that with the current list of active clusters, if add a new one (even with a configuration as minimal as 1 master and 1 node), not only its creation fails but also the other (or at least) running clusters become unhealthy. If I delete the failed cluster, the other clusters return to the healthy state. It seems very reproducible (I did it more than 10 times) but I still don't see any message in the logs that could help to identify the cause. I've the feeling (but may be wrong) that it is related to either an insufficient project quota or an insufficient limit on one of the OpenStack service. Any idea on a possible cause or any advice on where to look for some information? Thanks in advance. Michel

[all] SQLAlchemy minimum requirement
by Pierre Riteau 03 Jun '24

03 Jun '24

Hello everyone, Historically, many projects were using the following requirement for SQLAlchemy: SQLAlchemy!=1.1.5,!=1.1.6,!=1.1.7,!=1.1.8,>=1.0.10 These banned versions were present in global-requirements.txt until earlier this month [1]. The remaining projects with the above requirement must change it to fix their requirements-check job (ERROR: Requirement for package SQLAlchemy excludes a version not excluded in the global list). While fixing the requirement for blazar, I realised that OpenStack projects are using a wide range of minimum requirements. For example, networking-sfc had already bumped the minimum to SQLAlchemy 2.0 [2], although this is being reverted [3]. While all projects must be compatible with the upper constraint (currently 2.0.30), should we agree on a maximum version for the lower bound? The 2024.2 release targets Ubuntu Jammy, which includes python3-sqlalchemy 1.4.31, and Debian bookworm, which includes python3-sqlalchemy 1.4.46. Thanks, Pierre Riteau (priteau) [1] https://review.opendev.org/c/openstack/requirements/+/879743 [2] https://review.opendev.org/c/openstack/networking-sfc/+/920046 [3] https://review.opendev.org/c/openstack/networking-sfc/+/920868

The outbound unicast traffic of VMS with security group enabled is broadcast

hello everyone， Here is a description of a bug I encountered using openstack Security Group,If security groups are enabled for virtual nics on cloud hosts, The outgoing traffic of the VMS enabled in the security group should be sent in unicast mode, but it is eventually forwarded to all ports in the vlan on the ovs br-int bridge. Does the openstack open source community have a patch to fix this bug? Can you provide patch? The following is my debugging process in detail. The unicast packet sent by the remote virtual machine 172.83.160.63 to the local virtual machine 172.83.160.74 is passed to the br-ex->br-int-> VM, Because the security group is enabled on the VM NIC, The br-int cannot learn the entry whose port is patch-ex and mac address is vm2.

[neutron][all] OOM killer on coverage job
by Brian Haley 30 May '24

30 May '24

Hi, Neutron has been having issues with our coverage gate job triggering the OOM killer since last week [0], which I just confirmed by holding a node and looking in the logs. It started happening after the sqlalchemy 2.0 bump [1], but that just might be exposing the underlying issue. Running locally I can see via /proc/meminfo that memory is getting consumed: MemTotal: 8123628 kB MemFree: 1108404 kB And via ps it's the coverage processes doing it: PID %MEM RSS PPID TIME NLWP WCHAN COMMAND 4315 30.9 2516348 4314 01:29:07 1 - /opt/stack/neutron/.tox/cover/bin/python /opt/stack/neutron/.tox/cover/bin/coverage run --source neutron --parallel-mode -m stestr.subunit_runner.run discover -t ./ ./neutron/tests/unit --load-list /tmp/tmp0rhqfwhz 4313 30.0 2437500 4312 01:28:50 1 - /opt/stack/neutron/.tox/cover/bin/python /opt/stack/neutron/.tox/cover/bin/coverage run --source neutron --parallel-mode -m stestr.subunit_runner.run discover -t ./ ./neutron/tests/unit --load-list /tmp/tmpfzmqyuub (and the test hasn't even finished yet) Only workaround seems to be reducing concurrency [2].

[Diskimage-builder]Supported architectures for creating OS images in Diskimage-builder
by Junya Noguchi (Fujitsu) 29 May '24

29 May '24

To whom it may concern I am investigating which Linux distributions and versions for aarch64 are supported by Diskimage-builder. I found that many newer versions of Linux distributions are supported*, but there is no information about supported architectures in the commit messages. * References: Ubuntu: https://review.opendev.org/c/openstack/project-config/+/916050 RHEL: https://review.opendev.org/c/openstack/diskimage-builder/+/877347 SLES: https://review.opendev.org/c/openstack/diskimage-builder/+/619186 SUSE: https://review.opendev.org/c/openstack/diskimage-builder/+/908421 CentOS: https://review.opendev.org/c/openstack/tripleo-quickstart/+/843102 Does Diskimage-builder support building aarch64 images for those distributions? If not, a list of supported distros for aarch64, would be helpful. Best regards, Junya Noguchi.
