I tried, but it did not work:

# grep /sys/fs/cgroup /etc/fstab
systemd /sys/fs/cgroup cgroup none,name=systemd

# mount /sys/fs/cgroup

# lxc-start -P /data2/lxc -n lxc10 -F
lxc-start: cgfsng.c: all_controllers_found: 431 no systemd controller mountpoint found
lxc-start: start.c: lxc_spawn: 1079 failed initializing cgroup support
lxc-start: start.c: __lxc_start: 1329 failed to spawn 'lxc10'
lxc-start: lxc_start.c: main: 344 The container failed to start.
lxc-start: lxc_start.c: main: 348 Additional information can be obtained by setting the --logfile and --logpriority options.
