Hi,

when i start a Domain and the local block device is mounted i got an error message from xm, as expected.
When i run a DomU from a SAN (FC Storrage) xm lets me happyly start the same DomU wiht the same filesystem on another Dom0. I have 2 Dom0 Server connected to the same FC Disks, managed by clvmd. Is there any way to prevent this scenario from happening because after booting the 2nd DomU with the same filesystem it is doomed.....

regards Martin
