I'm not running a HVM - only PVM :-) - I have upgraded xen to 3.4.3 so I
have the "correct" pygrub and I have my drbd configured with allow two
primaries. The live migration works IF I manually control the
promotion/demotion of the drbd resource or if I leave the drbd resource in
primary/primary mode and I use the phy:/dev/drbdresource notation in the
domU config. If I use the drbd:drbdresource in the domU config then nothing
works - not even starting the domU

Thanks

S.
