[CRIU] system configuration for dumping/restoring LXC

[Krystof Zmudzinski]

It seems to have worked.  


18928 pts/1    S+     0:00              |   |           \_ /bin/bash ./run.sh test-lxc
19004 pts/1    S+     0:00              |   |               \_ /root/criu-1.3/criu restore --evasive-devices --tcp-established --manage-cgroup
19005 ?        Ss     0:00              |   |                   \_ /sbin/init
19029 ?        Ss     0:00              |   |                       \_ crond
19030 ?        Ss     0:00              |   |                       \_ /usr/sbin/httpd
19038 ?        S      0:00              |   |                       |   \_ /usr/sbin/httpd
19031 ?        Ss     0:00              |   |                       \_ sendmail: Queue runner at 01:00:00 for /var/spool/clientmqueue
19032 ?        Ss     0:00              |   |                       \_ sendmail: accepting connections
19033 ?        Ss     0:00              |   |                       \_ /usr/sbin/saslauthd -m /var/run/saslauthd -a pam -n 2
19037 ?        S      0:00              |   |                       |   \_ /usr/sbin/saslauthd -m /var/run/saslauthd -a pam -n 2
19034 ?        Ss     0:00              |   |                       \_ xinetd -stayalive -pidfile /var/run/xinetd.pid
19035 ?        Ss     0:00              |   |                       \_ /usr/sbin/sshd
19036 ?        Sl     0:00              |   |                       \_ /sbin/rsyslogd -i /var/run/syslogd.pid -c 5

The only problem is that the new container can't be restored with the -d option:

19507 pts/1    S+     0:00              |   |               \_ /root/criu-1.3/criu restore --evasive-devices --tcp-established --manage-cgroup
19508 pts/1    t+     0:00              |   |               \_ /root/criu-1.3/criu restore --evasive-devices --tcp-established --manage-cgroup

Could you add --manage-cgroups for dump and restore commands.
