Test
- start two vms (vm_a, vm_b)
- in a
- do writes from set A
- do writes from set B
- fix bitmap md5
- clear bitmap
- do writes from set A
- start migration
- than, in b
- wait vm start (postcopy should start)
- do writes from set B
- check btimap md5
The test should verify postcopy migration and than merging with delta
(changes in target, during postcopy process).
