[Bug 1943990] Re: After updating systemd packages to 245.4-4ubuntu3.13 and libvirt packages to 6.0.0-0ubuntu8.14, it is no longer possible to start kvm virtual machines

[Gerd Jakobovitsch]

As I stated in the comment, I downgraded the systemd packages to 3.11 to
try to get to a working state, but the error persisted after the
downgrade.

To get the full picture, these were the updated packages after which kvm
stopped to work:

  Trying to start a virtual machine from openstack, it defines the
  machine, but is not able to execute it.

  I used to have libvirt apparmor errors, but disabling libvirt in apparmor didn't solve the problem:
  [   27.785713] audit: type=1400 audit(1631888214.441:67): apparmor="DENIED" operation="capable" profile="libvirtd" pid=4817 comm="libvirtd" capability=17  capname="sys_rawio"
