Xen users - May 2009 - Giving multiple interfaces to a xen guest

Is there a cook book on "How to assign more than one interface card to a
xen guest" ? I have seen references in the /etc/xen/scripts dir, but all
I want to do is to give eth0 and eth1 in 2 different subnets to my xen
guests. I had assumed that the virt-manager would do this for me but I
was wrong. Any help or pointing to a previously done script is greatly
appreciated.

Hi Matthew,

You'd use the network-bridge script in the scripts directory to create 2
bridges: xenbr0 and xenbr1.  Each of these is bridging eth0 and eth1
respectively.  Then you'll attach each bridge to the guest in its config
file.

You should be able to get both bridges to start up at boot by editing the Xen
config file in /etc/xen

Is there a more verbose solution to this?  What should I change and
how?...It looks rather confusing.

Yeah, Xen networking does take a bit of getting used to.

For the specific query, go to 
http://wiki.xensource.com/xenwiki/XenNetworking and look under 
"Additional Notes" under "Bridging" (or search for
"(network-script
my-network-script)". There is a step by step guide to doing it. 
Assuming you are using Xen 3.0 or 3.2, then follow the steps listed 
under "With Xen 3.0 the best method ..." or "With Xen 3.2.1"
