I'm afraid I can't be of much help here. As far as I know, it should
be the GENERIC kernel. So no, I don't think you don't need to build
any kernel.

But I don't know why your router is not showing up. AFAICT, if it
shows when booting without Xen, it should also show with Xen. Maybe
the more experienced people in the list can help.

PS: Make sure you cc the mailing list when replying. That way, other
people who might have answers to your questions can see the entire
conversation.
