Xen networkin


Hi,
Just got my first Xen guest working (after I found the xen-tools). But now I want the guest to have access to both network cards on my PC as eth0 and eth1. But I have no success!

I found some documentation at http://wiki.xensource.com/xenwiki/XenNetworking
There also they show a custom script that should work for me:
#!/bin/sh
dir=$(dirname "$0")
"$dir/network-bridge" "$@" vifnum=0
"$dir/network-bridge" "$@" vifnum=1

Bot on 'xm create ...' it complains that it cannot connect to backend.
So I added manually xenbr0 and xenbr1 to Dom0 /etc/network/interfaces.
(Although that was not necessry when I used only one nic!)

One connection now works, but the rest seems to be mixed up.
I am out of my depth with virtual networking. Any help welcome.

I use Debian etch for Dom0, DomU on AMD64
BTW utltimately I want to run LTSP on one DomU (development) and a webserver (production) on another. Any feedback on that idea?

Thank you
Ernst

there is a lot of unnoficial advice which tears the standard xen network configs to shreds and makes it a lot simpler and better, fgor example: http://albertptobey.blogspot.com/200...etworking.html and http://renial.net/weblog/2007/02/27/xen-vlan/

they simplify the networking to a very non-Xen specific level which makes it a doddle.
