[Gllug] Xen and bridging

Sadly, a fixed Xen kernel has not yet been posted for Fedora FC5 so this
is all still a theoretical conversation and apologies for the possible
stupidity of some of the questions.

As I understand it running Xen on my machine means establishing an
ethernet bridge between the hypervisor and the guests.

I have to confess I knew nothing about bridges before and now I've read
this: http://linux-net.osdl.org/index.php/Bridge I at least know
something.

But how does routing work? Specifically how can I ssh into the box as user
A who only has an account on a specific guest system and get a prompt for
that system? I am assuming that xen will let each guest access the NIC and
I don't need a NIC per guest.

Is it the case that I have to set up NAT on top of the bridge?
