Public bug reported:
On guest start I see:
apparmor="DENIED" operation="open"
profile="libvirt-785b6ea8-24b9-4d9f-9e6e-6a08ac8a95ff" name="/"·
apparmor="DENIED" operation="open"
profile="libvirt-785b6ea8-24b9-4d9f-9e6e-6a08ac8a95ff"
name="/sys/bus/nd/devices/"
The latter could be allowed if we understand why it happens?
The former looks like a programming error and I'd want to know where it comes
from exactly.
