== Image size minimization ==
CPT needs to save all the VE data to a file after VE was suspended and to transfer this file to the destination node before VE can be restored. It means that migration latency is proportional to total size of this image file.

they can be much larger, when the VE to be migrated runs processes which use lots of virtual memory.
