We programatically, on a per VM basis, set up our ebtables and 
iptables rules at pmman.com (thus my 'ROADMAP' question 
earlier this week).  Under RHEL 6's (and thus CentOS') KVM 
and libvirtd stock setup, there was a built-in filter as 
provided by libvirtd install -- as I recall: a 'clean-traffic' 
filter -- that we had to amend out, compared to prior xen 
setups under the earlier RHEL variant

Have you dumped and examined the running rules affecting IPv6 
traffic?
