hi again. I'm wondering if my setup is so silly that all as ignoring it :) Meanwhile, I'm trawling this mailing list and searching online and there is nothing i see that might be of any help. If anyone with knowledge of lxc networking would be kind enough to tell me whether I'm mad or not, then I could keep looking for give up on passing a macvlan host interface to the LXC physically. That would be most kind. _______________________________________________ lxc-users mailing list lxc-users@lists.linuxcontainers.org http://lists.linuxcontainers.org/listinfo/lxc-users
