[Xen-users] Centos 5.2, Xen 3.2.1 and Bridge Problems

["Robert Dunkley" <Robert@xxxxxxxxx>]

I’m running Centos 5.2 with Xen 3.2.1 installed. The default bridge config of attaching “virbr0” to eth/peth0 works but I need to create two bridges, one on eth0 and one on eth1.

 

I have tried the script here:

http://www.centos.org/docs/5/html/5.1/Virtualization_Guide/ch-virt-bridge-errors.html

 

It does nothing different on startup (Despite editing Xend-config.sxp). If I manually execute it with ./script start then it kills all network connections to the server. I have reset the server to its default single bridge config, does anyone know how to get two bridges up and running?

 

Below are details of the working default single bridge config.

 

Thanks,

 

Rob
