------- Comment #1 from userlame@xxxxxxxxxxxx  2007-12-16 18:22 -------
I'm seeing the exact same behavior on the latest opensuse kernel 2.6.22.13-0.3.
It completely prevents save, migrate anything that tries to suspend. The save
or migrate command in dom0 will hang forever and the domU is renamed to
migrating-domU. The "last sysfs file" part was always
/devices/virtual/net/eth0/type, and I tried starting the domain with no vif but
it just changed to lo/type.
