Perhaps it's a systemd issue because after qemu-kvm session was killed
systemd still had a unit hanging about for it that prevented me from
restarting the vm until I rebooted the host.

I did verify that no qemu/kvm was running after.  Aside from that I have
no 'special' steps to reproduce other than that I had libvirt-bin and a
guest running, did an upgrade and discovered by guest was gone and I
couldn't restart it.

Daniel
