------- Comment #1 from dokter@xxxxxxxxxxxxx  2010-09-01 01:58 -------
I ran into the same bug as it seems, so I'll provide some additional log
output. 
I am running Xen 4.0.1-RELEASE with a 2.6.32.19-xen pvops dom0 kernel on ubuntu
server 10.04.1. 
I tried save/restore/migrate on ubuntu PVMs stored on file image and on
drbd/lvm partition via kernel stored on dom0 filesystem and via pvgrub. The
result was always the same.
