And the "Stateless autoconfiguration" diagram seems to be exactly what I think we'd want. Every guest has a MAC addr so that deals with the lower 64-bits of the adress, but how do we choose the upper 64-bits to form our 'router advertisment'... Perhaps that's the bit that we stick in the libvirt XML as the configuration parameter
IPv6 has a way that hosts can choose a (semi-)random upper 64 bits as well. Unfortunately as far as I can see it's deprecated :-(
Anyhow, you can read more about it here: http://www.faqs.org/rfcs/rfc3513.html (section 2.5.6) http://www.faqs.org/rfcs/rfc3879.htmlYou might also consider using link-local addresses (which are not deprecated), since the guests are supposed to be directly connected to each other. I'm not sure of the implications of that though ...?
