Should be possible. Bridge mode passes ethernet packets, and doesn't
really care what's on top of it.

dump "ip" settings. It's useless in most setup anyway. Instead, you
should explicitly specify mac (needed for lots of things, including
persistent DHCP), and optionally bridge (to make it clear, in case you
have multiple bridge) and vifname (to make it easier to identify from
dom0). Something like

vif = [ 'mac=00:16:3E:A8:31:24, bridge=eth0, vifname=ubuntu-e0' ]

Then specify ipv6 address inside domU using usual OS methods
(/etc/network/interfaces on Debian/Ubuntu)

Most modern OS have IPv6 enabled by default, using link-local address.
So if (for example) your dom0 bridge is using fe80::21e:bff:fe5e:9f58,
and your domU only has one interface (eth0), you can test IPv6
conectivity from domU to dom0 using something like

ping6 -I eth0 fe80::21e:bff:fe5e:9f58
