lxc-container support has not been properly implemented in
batman-adv yet. So things are not always working "naturely" and can
even make your system crash (e.g. rebooting an lxc-container makes
your system crash [0]).

What I usually did was configuring batman-adv properly on the host
via batctl. And only in the end adding it to the lxc-container.
That seemed to work for me (except the reboot crash noted above).
