I've tested this with simple loop, launch page-server serveral times with the same image directory
 on dest-host.

perform criu pre-dump and dump with page-server param, and copy the rest files.

criu restore on dest-host succeed.

Does restoring succeed because of the simple loop process? or it just always do?

Thanks!
