Using virsh and related, I can easily set up the network on the VM as
a natted IP with dhcp. This is taken care of in the defaults for
virt-manager. I can also set up, (but not quite as easily) the
network the way I want on a CentOS/XEN host. Unfortunately CentOS
doesn't have a number of other features that I want/need.
So...is there some XML snippet I can add to the domain that will
do what I want automatically? Or is there a script (or maybe I need
to write one) that can be invoked to set up the interfaces?
I would certainly be appreciative to get some pointers on how to proceed.
To make what I want a little clearer:
My host has a routable IP address such as 123.45.67.89. I want my
VM to have the routable IP address 123.45.67.90.
Have you seen this?

Unless I misunderstand, all you need to do is create a bridge for the
interface in the host, connect the guest's network backend in the host
and statically configure the guest's interface with that IP address.
