On live migration with --p2p like:
$ virsh migrate --live --p2p kvmguest-bionic-normal \
qemu+ssh://10.6.221.80/system
We hit an apparmor deny like:
apparmor="DENIED" operation="file_inherit"
profile="/usr/sbin/libvirtd" pid=23477 comm="ssh" family="unix"
sock_type="stream" protocol=0 requested_mask="send receive"
denied_mask="send" addr=none peer_addr=none peer="unconfined"
The rule is not perfect, but can't be restricted further at the moment
(new upstream kernel features needed). For now the lack of a profile on the
peer as well as comm not being a conditional on rules do not allow to filter
further.
