DB> mkdir /dev/cgroups/libvirt/lxc/{NAME} I have a small (and not-yet-working) patch that uses libcgroup[1] to setup a cgroup per container. This provides the ability to enforce the <memory> quantity on the group through memory.limit_in_bytes. I've also got some stubs that I plan to use to provide access to cpu.shares through the scheduling parameters interface.

I'm still working with the libcgroup folks to get some kinks ironed out, but I will post the patches when we get something that works against some version of libcgroup.
