[Libvirt-cim] [PATCH] Ensure graphics devices have unique IDs

[Chip Vincent]

The reason your not seeing a vnc instance is because libvirt-cim expects 
the 'listen' parameter. Please add 'listen=127.0.0.1' to the
graphics element, update the VM, and re-run the wbemcli and you should 
see an instance for vnc.
