For details of live migration see:
Other papers under:
If you run software that dirties large amounts of memory then the precopy
approach doesn't work very well: in this case, the live migration code
will figure it out and cuts its losses by doing "stop and copy" -
incurring a longer stoppage but more efficient use of network bandwidth.
For real world server workloads it works well: Running Quake 3 servers
incurred a downtime of about 60ms (I think), whilst an Apache webserver
running SpecWeb incurred a downtime of 300ms and didn't drop any clients.
