Public bug reported:

My focal host recently patched itself to the newest libvirt version
available in the Server Team Backports PPA
(https://launchpad.net/~canonical-server/+archive/ubuntu/server-
backports) which caused all my domains to shutdown and **not** restart
despite being marked for autostart.

The last log entry is me manually starting up a VM that is a critical
network service by simply doing a  virsh start <DOMAIN> after I realized
there was a problem.

It is very unexpected behavior for an upgrade to (cleanly) shutdown all
domains and not restart them.

** Affects: libvirt (Ubuntu)
     Importance: Undecided
         Status: New

** Description changed:

  My focal host recently patched itself to the newest libvirt version
  available in the Server Team Backports PPA
  (https://launchpad.net/~canonical-server/+archive/ubuntu/server-
  backports) which caused all my domains to shutdown and **not** restart
  despite being marked for autostart.
