Err, I'm a bit surprised. I haven't tested it since then, but I'm sure
live migration was working with stubdoms a few months ago, without
the need for a logdirty shared buffer.  This works thanks to the few
lines at the end of the cpu_physical_memory_rw() function that tell the
hypervisor about modified memory.  Actually, the plan was even to use
that bit of code in all cases (not only non-stubdom), so as to get rid
of the logdirty shared buffer completely.
