Are you using a bridge for xvifN.0 on the dom0?

Try using ping6 to the link-local (fe80::) addresses.   Remember to use
%ifname as it appears in ifconfig (other end's address, your ifname).

Try running tcpdump in promiscuous mode on both ends.  That can hide
some mcast programming/filtering bugs to help diagnosis.

First, ping the ll address of the xvif from the domU, and vice versa.
