[libvirt] sVirt support for LXC?

Hello, Is it planned to support sVirt for LXC? I know the current libvirt does not support sVirt for LXC. I found that a branch at https://gitorious.org/~berrange/libvirt/staging/commits/lxc-svirt seems to support sVirt for LXC. I downloaded the tar file and overwrite libvirt-0.9.6 with the branch. I could build and install it with a little modification of the source code which is mainly disabling 0.9.7 specific new methods. However, even with that, an LXC instance does not have proper sVirt labels. Could anyone tell me the status of sVirt support for LXC? Thanks, David.
