Comment 85 for bug 1787405

Tested 4.6.0-2ubuntu3.2~ppa1 from the PPA.
I can now add

    <hostdev mode='subsystem' type='mdev' managed='no' model='vfio-ap'>
      <source>
        <address uuid='24f952b3-03d1-4df2-9967-0d5f7d63d5f2'/>
      </source>
    </hostdev>

without getting display='off' added

- no new/different related apparmor issues
- starting the guest works fine
- generated qemu line LGTM
  -device vfio-ap,id=hostdev0,sysfsdev=/sys/bus/mdev/devices/24f952b3-03d1-4df2-9967-0d5f7d63d5f2
- guest sees AP adapter
- did a few start/stop cycles to check stability of getting the mdev back (to other guest after
  first shut down for example)

I have the same ready for Disco as 4.6.0-2ubuntu5 and will upload that now.

Once complete the 4.6.0-2ubuntu3.2 shall replace the libvirt currently in cosmic-proposed.
