Hi,

have now done the same.

With current git qemu migration is really fast using 1,6GB memory:
Dec 27 15:17:45 starting migration of VM 105 to node 'cloud1-1202' 
(10.255.0.20)
Dec 27 15:17:45 copying disk images
Dec 27 15:17:45 starting VM 105 on remote node 'cloud1-1202'
Dec 27 15:17:48 starting online/live migration on tcp:10.255.0.20:60000
Dec 27 15:17:48 migrate_set_speed: 8589934592
Dec 27 15:17:48 migrate_set_downtime: 0.05
Dec 27 15:17:52 migration speed: 512.00 MB/s - downtime 174 ms
Dec 27 15:17:52 migration status: completed
Dec 27 15:17:53 migration finished successfuly (duration 00:00:09)
TASK OK

It's so fast that i can't check if i see that's while migrating.

Greets,
Stefan
