I have apply this patch to bare 2.6.36.2 kernel from kernel.org. If
memory=maxmemory pv guest run's on migrating fine.
If on already running domU i have xm mem-max xxx 1024 (before that it
has 768) and do xm mem-set 1024 guest now have 1024 memory, but after
that it can't migrate to another host.

Step to try to start guest with memory=512 and maxmemory=1024 it boot
fine, xm mem-set work's fine, but.. it can't migrate. Sorry but nothing
on screen , how can i help to debug this problem?
