Hi Vinod,
I think unfortunately it is not acceptable to make this patch work only
for KVM. (It cannot work for Xen, but that's not a problem since Xen
uses a different migration mechanism; but it should work for TCG).
Unfortunately, as you noted the run_on_cpu callbacks currently run
under the big QEMU lock. We need to fix that first. We have time
for that during 1.6.
