Which would make sense, since host iptables is not dealing with guest IPv6 packets. So, the real cause of this bug is the bridge making host ip6tables deal with guest IPv6 packets ? If so, would it be ok if write a patch testing ipv6_mod_enabled() before passing guest ipv6 packets to host ip6tables?
