Bug 251666

This is still happening with EL5.1 beta.

When I reboot my dom0 machine, or simply run "service xendomains stop", the
output for when saving the domains is confusing and ugly : Output indicates that
processes have been terminated and some devices aren't connected, while in fact
things are (usually) working fine. The terminated processes seem to be the
watchdog processes.

Sample output :

[root@x195 ~]# xm list

Restoring saved domains isn't much better :

[root@x195 ~]# service xendomains start
Restoring Xen domains: b01 emd01 lost+foundError: Restore failed
Usage: xm restore <CheckpointFile>

Restore a domain from a saved state.
! mc03 w03.
[root@x195 ~]# en domains: b01(skip) emd01(skip) mc03(skip)[  OK  ]p)

Not to mention that it doesn't even try to skip "lost+found", which is a
directory, since I have /var/lib/xen/save on its own partition to make sure I'll
always have enough free space to save all of the running domains (should I open
another bug report for it?).
