Hello everyone.  I caught an error when i was using the test for dumping/restoring an LXC container. The dumping step was all right , but the following error occurred  in the restoring step, which could be find in the restore.log.
(00.266862)      1: Error (tty.c:614): tty: Can't open 9 (index 0): Bad file descriptor

(00.298420) Error (cr-restore.c:1037): 35921 exited, status=255

(00.298463) Error (cr-restore.c:1579): Restoring FAILED.
My OS is Ubuntu13.10. I have set lxc.console=none lxc.tty = 0 and removed the "lxc.cgroup.devices.allow = c 5:1 rwm" from the container config.
