Bug description:
  In a site upgraded to Ussuri we are getting faults starting instances

  2020-11-30 13:41:40.586 232871 ERROR oslo_messaging.rpc.server
  libvirt.libvirtError: Requested operation is not valid: format of
  backing image '/var/lib/nova/instances/_base/xxx' of image
  '/var/lib/nova/instances/xxx' was not specified in the image metadata
  (See https://libvirt.org/kbase/backing_chains.html for
  troubleshooting)

  Bug #1864020 reports similar symptoms, where due to an upstream change
  in Libvirt v6.0.0+ images need the backing format specified.

  The fix for Bug #1864020 handles the case for new instances. However,
  for upgraded instances we're hitting the same problem, as those still
  don't have backing format specified.
