Re: [Libvir] [PATCH] Add a default network

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:

You 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 ...?
