Trying to reproduce, where the vm is already defined (because
installation failed but definition remained) now I get the L2 vm that
goes into paused mode and not able to have it exit from this state.

L1 f6 is f16vm
L2 f16 is f16vmvm

Tried with these L2 vms:
- winxp configured to start from cd iso
- f16vmvm configured to start form cd iso where I have CentOS 5.6 live

For example starting the f16vmvm (so the L2 one) I see it after a few
seconds in paused state in virt-manager of f16vm (L1 one).

[root at f16vm ~]# virsh list
 Id Name                 State
----------------------------------
  1 f16vmvm              paused

[root at f16vm ~]# virsh domstate f16vmvm --reason
paused (unknown)

Donna how to (try to) unpause it... clicking the pause button in
virt-manager does nothing...

I will try to reproduce the freeze during new vm install too...
