--- Comment #8 from Paul G Webster <paul at tmp.group> ---
The host provided the following information for what they had to do with
ebtables to get freebsd working;

We use ebtables on the hosts to prevent IP stealing.

We have a chain setup for each VM which basically says "this VMs mac can only
use these IPs", this is what was dropping your v6 NA's.

The patch to allow the link local address is simply:
ebtables -A kvm922.0 -p IPv6 --ip6-src fe80::/10 -j ACCEPT

With kvm922.0 being the chain that your VM belongs to.
