Comment 4 for bug 1561434

Just new I tried the updated CRIU:

>> Linux Image Version: 4.4.0.15.16
>> CRIU Version: 2.0-2ubuntu2
>> LXC Version: 2.0.0~rc12-0ubuntu1

The checkpoint step became success, but recovery step failed:

+ lxc-checkpoint -s -D /var/lib/lxc/cr-test/cp -n cr-test

+ lxc-checkpoint -r -D /var/lib/lxc/cr-test/cp -n cr-test
