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 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:
