Jitterd Test
I ran jitterd in a migrating VM of size 8GB with and w/o the patch
series.
./jitterd -f -m 1 -p 100 -r 40
That is to report the jitter of greater than 400ms during the interval
of 40 seconds.
Jitter in ms. with the migration thread.
Run Total (Peak)
1 No chatter
2 No chatter
3 No chatter

Jitter in ms. without migration thread.
Run Total (Peak)
1 4663 (2413)
2 643 (423)
3 1973 (1817)

Flood ping test : ping to the migrating VM from a third machine (data
over 3 runs)
Latency (ms) ping to a non-migrating VM : Avg 0.156, Max: 0.96
Latency (ms) with migration thread : Avg 0.215, Max: 280
Latency (ms) without migration thread : Avg 6.47, Max: 4562
Very impressive numbers.
