Comment # 13 on bug 1203458 from Daniel Scott

I created a new VM and had the same result. I started the VM a bit differently
and found something that perhaps provides a clue.

I opened the VM from the virt-manager. Then, from the hardware details tab I
started the VM. No issue. I switched to the graphical console tab and
immediately both the virt-manager and the console windows closed. As before,
starting virt-manager again shows the VM running.

Also, if I start the VM from virt-manger and then open it, that immediately
shuts virt-manager down.
