Whatever caused my earlier migration attemts to fail is now gone with
two xen 4.1 boxes and a recent domU kernel (debian unstable 2.6.38).

My test setup is now:

1 debian squeeze dom0 box with xen 4.1 from debian unstable and

1 ubuntu natty dom0 box with recompiled xen 4.1 debian unstable packages
and a self compiled dom0 kernel from the 2.6.32-stable git.

With this setup I tested migration with file:/<pathto>/domU.img
configuration and nfs shared storage and with a
phy:/<pathto-drbd-device> (dual primary) setup. Both methods seem to
work fine with my debian-unstable test-domU. With a debian squeeze
(2.6.32 distribution kernel) the migration works on the xen-dom0 part,
but the domU kernel doesn't seem to handle the save/restore too well and

Didn't have time to test any new 2.6.39rc* images...
