First off, I am rather new to Xen and looked through the archives but could not locate a solution to my problem . In my Dom0 configuration I have 2 nics (eth0 & eth1. Eth0 and Eth1 are boned and appear as bond0. I installed Xen and all network traffic over bond works fine. I installed a Redhat ES 5 as DomU. When I boot the image, it does not pickup any networking from Dom0. I have tried editing xend-config.sxp and changed the line:

(network-script network-bridge) To (network-script 'network-bridge netdev=bond0')

Still nothing. I even went as far as removing the bonded interface and running eth0/eth1 as normal and I still am not able to get networking up for DomU. When I added the netdev=bond0 it killed all networking for Dom0 and DomU. What am I doing wrong? There is nothing in the documentation about this... Any help would be great.

Thanks
Andrew

Andrew,
Xen renames eth0 to peth0 and creates a bridge named eth0. Are you sure that your bond is working after xend starts up? Generally you have to rename the actual physical device eth0 or use custom network-scripts to keep this from happening with a bond.
