Thank you all for your input. The disks are raw devices, the domU is 
directly installed onto it, not in a file on a filesystem on that device.

The reason why I am aksing is, I want to use virtual Xen nodes in a Cluster, 
and I want to know when on one node the virtual domain is paused, and I 
start the same domain on a different host, whether it will trash my 
filesystem for that node, or whether I can do that without damage?
It's about how I will treat a paused virtual domain in the cluster, either 
as running or as stopped.

kind regards
