This is a fairly normal config when bridging, since the eth0 and all
vifs are going to be on the same layer 2 network they can all take
addresses from the same network.


Thanks for the detailed response!  I've been informed this bridging
functionality may have been broken in certain versions of Xen,
such as 2.0.7 (stable), which is what I was using.

Might I inquire as to which version of Xen you're running?

Bill, your exact scenario is still not understood.
Are you using one physical NIC with multiple IPs (aliases)?

If your initial configuration was an interface with
multiple IPs, then not all IPs got transferred from
the phyical interface to the virtual one we create.
Those, however, have nothing to do with the interfaces
in domU.

Note that domU interfaces are created independently
and are virtual.
