Okay, and once we "lost" xend, there is no way to do anything ? (create, 
destroy, shutdown, get a console...)

I will do my best to reboot the box and try to reproduce the problem. 
But if the restore operation crashes xend, I will never be able to get a 
crash dump - unless there's another way to get the information ?
If I don't use save/restore/migrate, can I expect Xen to be stable ? Or 
are there other features that are deemed to cause problems ?
