Hi everyone, if anyone ever will happen to restore an image backup of a XEN VM Server 2008 R2 into another VM, not the original, that backup was taken from, to prevent BSOD, while the machine is powered off, via the console of Citrix XEN host use this command (in my case ID=0002 helped).
xe vm-param-set uuid=<vm_uuid> platform:device_id=0001
or
xe vm-param-set uuid=<vm_uuid> platform:device_id=0002
For the restoration I used Restore CD 1.2WIP2
Cheers,
Alex
