Is there a version of qemu that works on Focal that deployment projects could use now?
Not that I'm aware of, I don't believe Canonical have a UCA for Focal yet, let alone one that has a version of QEMU that doesn't hit this issue. It's worth noting that we haven't been able to reproduce this outside of OpenStack CI *and* similar sized nested test environments running the tox -e full Tempest target on Focal or Bionic with the Ussuri UCA. I've personally been unable to reproduce this on Fedora 32 with or without the virt-preview repo.
We use the train ubuntu cloud archive to get an unaffected qemu version, which is now 4.0
We are proposing doing this on our current Bionic based CI hosts so we can still go ahead with a planned min version bump in V: https://review.opendev.org/#/q/status:open+topic:bump-libvirt-qemu-victoria

Hi,
I want to raise a potential conflict between the fact that OpenStack Victoria officially supports Ubuntu Focal[3] and a high severity regression in Nova [1] caused by a qemu bug [2] in the qemu version that is shipped with Focal.
The Nova team documented[4] it as a limitation without a known workaround in Nova. Also as far as I know Canonical does not support downgrading the qemu version so I don't see a viable workaround on Focal side either.
Is the Nova reno[4] enough from the TC perspective to go forward with the switch to Focal and with the Victoria release?
cheers, gibi
