My question rephrased is: if I have 2 bridges in dom0 (say xenbr0 and xenbr1)
does dom0 require a configured IP address on each bridge?

My instincts told me no, but my experiment showed otherwise.

Imagine the simplest case of one physical interface. You don't want
the interface in dom0 to have IP address, but you still want to
provide networking to the guests via the bridge configured in dom0. Is
this possible?

I think it must be and either I'm doing something wrong or that I'm
experiencing a limitation in the tools (either those provided by Xen
or from SUSE) but I was hoping to get some confirmation before I dig
any deeper.

Thanks,
