Right, but one end is a virtual router, the connectivity is virtual
ethernet, and the other end is a VM running an unknown OS. dhcpv6 has poor
prevalence in such OS, and in any case I can't without using dhcp in a
non-standard way determine the device by the MAC address I've given it, and
circuit ID methods require similar hacks; none of that is attractive. So
that leaves me with autoconfig and a /64.
