Hi Ronan,

do you want to do something like this (see the image) ?

After reading a lot of stuff I made a wrapper of network-bridge, that I call network-bridge-wrapper, here is it:

#!/bin/sh
/etc/xen/scripts/network-bridge start bridge=xenbr0 vifnum=0
/usr/sbin/brctl addbr xenbr1
/sbin/ifconfig xenbr1 up

I changed the line in xend-config.sxp that calls, network-bridge to call network-bridge-wrapper ...

If you want I can post more info about this config (my domu config files, iptables, ebtables....). I'm using Debian, so... I hope scripts in CentOS are so close to Debian.

Regards,

Marc

My situation:
Running centos5 on a machine directly connected to internet.
I have a paravirtualised centos5 core machine in domu1 with only 1 eth configured eth0 dy dhcp.

What I want:
to configure the dom0 bridge to simply route all traffic at ethernet level to dom1(firewall/router) and have dom1 then nat if out to my other domu's and machines on my private 192.168 network using dhcpd configured on eth1 on the machine.

My difficulties:
setting up the dom0 bridging to do what i want ie xenbr0 to eth0 on domu1 and then xenbr1 to eth1 on domu1

I then intend to remove / lock dom0 down and only use the domu's as dhcp configured servers.

There are a couple of URLs i've looked at
http://lists.xensource.com/archives/html/xen-users/2006-02/msg00602.html

etc but there aren't any specific configuration information.
Can i get some pointers as to where to look, or even example configs?

thanks

Ronan

(ps if this is the 3rd like message of mine today i apologise, I can tell if the other two messages i send actually did...)
