[CRIU] PID mismatch problem

[Federico Reghenzani]

My call is
ssh 0.0.0.0 orted-restore

This is the code I've used for restore in orted-restore:

    criu_init_opts();
    if(0 > (dir = open(path, O_DIRECTORY))){
               ....
    }
    criu_set_images_dir_fd(dir);
    criu_set_log_file("criu_restore.log");
    criu_set_log_level(4);
    int status = criu_restore();

Also I have noticed that orted (the restored process) is an init child (not
orted-restore child) but I have no stdout, stderr on ssh (with or without
criu_set_shell_job) probably because it's a init child and not a
orted-restore child.


Cheers,
Federico
