Comment 22 for bug 1829823

On xenial, I installed libvirt-bin 1.3.1-1ubuntu10.27 from -updates,
as well as virt-manager and qemu-system. I installed a bionic desktop VM and
issued "sudo shutdown -h now". libvirt-guests then connected to the VM and shut
it down gracefully before the system was shut down.

I then upgraded libvirt-bin to 1.3.1-1ubuntu10.28 from -proposed, started the
bionic VM and issued a system shutdown. Again, libvirt-guests then connected to
the VM and shut it down gracefully before the system was shut down.

The package is still a nop on xenial, and does not cause any regressions.

I looked at the debdiff for 1.3.1-1ubuntu10.28 and applied the changes to a
trusty system, where I had previously reproduced the problem. The modifications
from the debdiff made trusty libvirt-bin respect libvirt-guests, and the VM
that was running was shutdown gracefully before the system was shut down.

I am happy to mark this bug as verified, as I am happy that xenial will not
suffer any regressions, and that once the package makes its way into the
trusty mitaka cloud archive, the issue will be fixed.
