We know that the current design is not sufficient. This is exactly the 
reason why I am working right now on new one that will give abilities to the 
manager to change PCI addresses per device.  But in any case we planning 
that the first addresses allocation will be done by libvirt and vdsm will 
return it to the manager.
I am not sure whether it will be accessible via GUI. Livnat?
