I just pushed https://gitlab.cri.epita.fr/cri/packages/kolla-ansible/-/tags/12.2.0-cri-1, which is the first step towards resolving this.

The procedure to apply the fix is as follows:

• Disable the compute host: openstack compute service set <host> nova-compute --disable
• Migrate all VMs from it one by one
  • Make sure there is none left by running docker exec -it nova_libvirt virsh list on the compute host.
• Run kolla-ansible deploy --limit <host> with options as specified in kolla/README.md
• Enable the host with openstack compute service set <host> nova-compute --enable

Here is the list of the compute nodes on which this fix has been applied:

• compute-1.bm.cri.epita.fr
• compute-2.bm.cri.epita.fr
• compute-3.bm.cri.epita.fr
• compute-4.bm.cri.epita.fr
• compute-5.bm.cri.epita.fr
• compute-6.bm.cri.epita.fr
• compute-7.bm.cri.epita.fr
• compute-8.bm.cri.epita.fr
• compute-9.bm.cri.epita.fr
• compute-13.bm.cri.epita.fr
• compute-14.bm.cri.epita.fr
• compute-15.bm.cri.epita.fr
• compute-16.bm.cri.epita.fr
• compute-17.bm.cri.epita.fr
• compute-18.bm.cri.epita.fr

I'm also running a kolla-ansible pull on each host before re-deploying to make sure we're up-to-date.

And while I'm at it, apt update && apt upgrade -y && reboot
