And finally, perhaps you have NX disabled in the bios of one of the

What does 'dmesg | grep NX' show on both hosts?
nx was disabled on one of the nodes.
That explains the problem.
i will retry the case later today and send info register output.
what is the recommended value for nx (and why)?
Enabled (so you get no-execute memory protection).
do you have a guideline which flags should be identical to ensure proper
live migration?
i would like to do an automatic compare before life migration to avoid
crashes.
thanks

and why was it working with 2.6.34 and is not with 2.6.35-rc2?
We fixed a different bug. But you shouldn't live migrate from a
machine with nx to a machine without nx, unless you use -cpu ...,-nx
on both nodes.
