Title:
  libvirt cannot kill dhcp in containers

Status in isc-dhcp package in Ubuntu:
  Confirmed

Bug description:
  If I create a ubuntu container and start it as a libvirt-lxc
  container, it runs under the host dhcp profile.  Then when I try virsh
  -c lxc:/// destroy c1, libvirtd tries to kill dhcp in the container
  but fails:

  Jun  5 17:54:14 t1 kernel: [ 2563.620698] type=1400 audit(1401983654.375:28): apparmor="DENIED" operation="signal" profile="/sbin/dhclient" pid=4304 comm="libvirtd" requested_mask="receive" denied_mask="receive" signal=term peer="/usr/sbin/libvirtd"

  Jun  5 17:54:14 t1 kernel: [ 2563.660600] type=1400 audit(1401983654.415:30): apparmor="DENIED" operation="signal" profile="/sbin/dhclient" pid=4293 comm="libvirtd" requested_mask="receive" denied_mask="receive" signal=term peer="/usr/sbin/libvirtd"

  I don't actually understand the mechanisms here (that a profile should
  be able to refuse receiving signals), and it seems like the proper fix
  is to have libvirt-lxc start containers confined in a container
  policy, but Jamie seemed to have another solution, which would be
  great.
