Re: [Xen-users] advanced bridging...

[Marc Patino Gómez <mpatino@xxxxxxxxxxxx>]

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
