[CRIU] Docker - CRIU - Failed Checkpoint Restore

[Thouraya TH]

./docker-1.9.0-dev run --name test8-container -t ubuntu:latest
/bin/bash     (without -i option it didn't work also !)
root at 4812c6e86698:/# ls

Second Terminal:
/docker-1.9.0-dev checkpoint test8-container
Error response from daemon: Cannot checkpoint container test8-container:
criu failed: type NOTIFY errno 0
Error: failed to checkpoint one or more containers

My goal is to create a docker container (ubuntu), access to this container
(root at bcd7fcd5b0e1:/home#) and install some tools inside and do the dumping
process.

Any help please ?

Thanks a lot.
