Hi,
according to talk recently at BaLUG, they copy and note which pages have become "dirty" in the meantime, after a few cycles they then stop the vm and migrate the rest over, start it on the new one.
According to them, they've done that with a Quake3 server without the users noticing much. That sounds really impressive.
Apparently "downtimes" of ~200ms is typical when you have a 100Mbit link between the two hosting machines.
