[CRIU] Migration and Restart of http://criu.org/Simple_loop

[Thouraya TH]

Hello,

$ cat > test.sh <<-EOF
#!/bin/sh
while :; do
    sleep 1
    date
done
EOF
$ chmod +x *test.sh*

I'd like to migrate and  restart this process on a new machine.

*Fist of all*, i have done the *dumping process*:

root at g-71:/home# criu dump -vvvv -o dump.log -D imgDir -R -t 1249
--shell-job && echo OK
OK
root at g-71:/home# cd imgDir/
root at g-71:/home/imgDir# ls
cgroup.img      creds-1849.img  ext-files.img  filelocks.img
ids-1849.img   mm-1249.img    packetsk.img      pages-2.img
sigacts-1249.img  stats-dump
core-1249.img   creds-1967.img  fanotify.img   fs-1249.img
ids-1967.img   mm-1849.img    pagemap-1249.img  pipes-data.img
sigacts-1849.img  timerfd.img
core-1849.img   creds-1995.img  fdinfo-2.img   fs-1849.img
ids-1995.img   mm-1967.img    pagemap-1849.img  pipes.img
sigacts-1967.img  tty.img
core-1967.img   dump.log        fdinfo-3.img   fs-1967.img
inetsk.img     mm-1995.img    pagemap-1967.img  pstree.img
sigacts-1995.img  tty-info.img
core-1995.img   eventfd.img     fifo-data.img  fs-1995.img
inotify.img    netlinksk.img  pagemap-1995.img  reg-files.img
signalfd.img      tunfile.img
creds-1249.img  eventpoll.img   fifo.img       ids-1249.img
inventory.img  ns-files.img   pages-1.img       remap-fpath.img
sk-queues.img     unixsk.img

*Secondly*, i try to restart the process *on the same machine* but it
didn't work:

 criu restore -d -vvv -o restore.log && echo OK
 ps -C test.sh
  PID TTY          TIME CMD

restore.log

Have you an idea please ?

Thanks a lot.
