Sorry for such a basic question... but is the page fault handler
routine in the hypervisor preemptable?  For example, let's say guest
domain A is being live migrated.  As it's running, a page fault
occurs.  Can the page fault handler be preempted in the middle by say
the live migration process in dom0?

Thanks,
Mike
