Hi. I upgraded one of my servers to Ubuntu 20.04. Since then domains
won't shutdown. They are in the "in shutdown" state.
I googled around and I found it is probably because of apparmor.
I see this message in the logs:
kernel: [740222.848210] audit: type=1400 audit(1606983397.013:338):

Are you using lxc? I recently posted a patch allowing lxc domains to receive
signals from libvirtd

If you are using qemu, ensure the libvirt-qemu abstraction contains similar
rules. They were introduced in libvirt 5.2.0, so your libvirt-qemu abstraction
should already have them.
