I just noticed that a host of mine running as a Xen guest is not
getting (or maybe just sending) ipv6 packets correctly. It's running
pretty much the same as some physical hosts, and the only difference I
can see is the Xen (and vioif) aspect.
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.
