Hi,
thanks for your patches. I committed all of them to the kernel and
pkgsrc.

I've not looked at this in details yet. It shouldn't need much for a domU
that doens't have access to physical devices. A domU with physical devices
would probably require to save/restore the device's setups, which probably
requires a MI framework (not much different from what is needed for e.g.
ACPI suspend/resume).
For live migration, I don't know if there is additionnal support
needed on the domU's side, or if the hypervisor does all the extra work
(from what I remember, for a live migration, the domU's memory is copyed
while the domU's kernel is still running. Then the domU is suspended and
only pages that have been changed are transfered again).
