[Thouraya TH]

Hi all :)

I have done two tests with:
criu --version
Version: 1.6
GitID: v1.6-5-g5e1a8a2




*Test 1 ( Successful Checkpoint Restore ): *
First Terminal:

./docker-1.9.0-dev run -d --name *test6-container* ubuntu:latest /bin/sh -c
'i=0; while true; do echo $i; i=$(expr $i + 1); sleep 3; done'
67de0ff343a32b779fee58f1990aa50bfb0b99d2cc6066597fffef03c5b87839

./docker-1.9.0-dev ps -a
CONTAINER ID        IMAGE               COMMAND
CREATED             STATUS                      PORTS               NAMES
67de0ff343a3        ubuntu:lates        "/bin/sh -c 'i=0; whi"   10 seconds
ago      *Up *9 seconds                                   * test6-container*

Second Terminal:

./docker-1.9.0-dev checkpoint test6-container
test6-container

/docker-1.9.0-dev ps -a
CONTAINER ID        IMAGE               COMMAND

ago      *Checkpointed 4 seconds ago*                       test6-container

./docker-1.9.0-dev restore test6-container
test6-container

./docker-1.9.0-dev ps -a
CONTAINER ID        IMAGE               COMMAND
CREATED             STATUS                      PORTS               NAMES

Any help please ?
