Hmm, I don't know if I buy this. Closing a VNC client window doesn't shut down
the remote machine, nor does exiting an SSH connection. And doing virt-manager
--uuid <blah> doesn't auto-start an inactive VM so users are forced to
recognize this concept IMO.

There's also the issue that reliably shutting down a VM in a safe way is hard:
shutdown often doesn't do what's expected, and destroy is potentially
dangerous. If we just kick off 'shutdown' on exit then the user may not notice
for a long time that the VM never shut down.

I think I'd be more comfortable with just recommending a wrapper script if
someone really wants this functionality, it's basically:

virsh start <vmname>
virt-manager --no-fork --uuid $(virsh domuuid <vmname>)
virsh destroy <vmname>
