[Users] LXC in Debian 7 inside Debian 7 OVZ

[Narcis Garcia]

I'm using Linux 2.6.32-openvz-042stab113.11-i386 in a Debian Wheezy
server with Debian Wheezy containers.

I've tried to install previously LXC at hardware node, but cannot create
anything as /sys/fs/cgroup
(cannot create directory `/sys/fs/cgroup': No such file or directory)

Then lxc-checkconfig (at HN) notes 2 problems:
Cgroup namespace: CONFIG_CGROUP_NS missing
Cgroup memory controller: missing

Does anybody know if some of these guides are useful to use LXC inside
an OpenVZ container?

Thanks.
