Thanks Guido.

Actually, the Debian maintainer's documentation is quite misleading as it 
states that « If you use a Debian wheezy kernel or newer, all of the 
features are enabled including the resource controller. ».

The fact is you won't have this cgroup if you don't add the 
"cgroup_enable=memory" to the kernel command line ! As stated in more recent 
version of the Debian LXC package.

This did the trick for the lxc.cgroup.memory.limit_in_bytes control. 
Unfortunately, the wheezy Debian kernel has not enabled CONFIG_MEMCG_SWAP 
(does not even show up in the kernel config, may be this was not yet 
implemented in 3.2 kernels) so memsw doesn't work :-(.

Anyway, my problem's solved, mostly ! Thanks.
