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): apparmor="DENIED" operation="signal" profile="libvirt-a2c1456f-3371-49eb-9fa4-f8576ca4e878" pid=2375 comm="libvirtd" requested_mask="receive" denied_mask="receive" signal=term peer="libvirtd"
Are you using lxc? I recently posted a patch allowing lxc domains to receive signals from libvirtd https://www.redhat.com/archives/libvir-list/2020-December/msg00187.html 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. Regards, Jim
