I did restore the domain, then noticed it was crashed ("-----c" in xm list). I tried to destroy it, but it didn't work. So I stopped xend, restarted it ... And there it goes :

Restarting xend was a bit of a brave move. Although its intended
to be restartable, there are definitely bugs in the restart code,
particularly if you have domains in unusual states at the time
Okay, and once we "lost" xend, there is no way to do anything ? (create, destroy, shutdown, get a console...)

As to why the domain wouldn't be destroyed, that may turn out to
be a useful clue as to the resume problem at its root. If we
could get a crashdump from a known kernel image I'm sure we can
fix this pretty easily.
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 ?
