Xen users - Jun 2011 - PV migration process

Good day.

I''m still trying to get linux-3.0.0-rc3 works with XCP, and I found
that
kernel with single VCPU migrates fine and multiple VCPUs cause hangs 
with some probability.

And I starts to guess: what guest must to do during migration? I''m 
somehow understand what xen and it toolstack shall to do to migrate VM, 
but what exactly happens during migration inside virtual machine?
