Help with setting up Networking for XEN on CentOS 5.9

Hey guys, I've reached the point of setting up VM's on XEN but the net installations seem to be failing when I am in the netinstall on the actual VM, so this leads me to believe that the networking on the host machine is not set up correctly. I am running CentOS 5.9 along with XEN and was just wondering how I need to set up the network to get it all working
Hopefully this is enough to give you an idea of our network setup.


Code:

 Here is all of the details that 'ifconfig' returns:

All we want to do is point the static IP's that we have bought to the VPS's that we create, we're trying to get a leg up and everything just keeps falling over and it's incredibly annoying. Right now we can't get past the netinstall because I think the bridges are not set up correctly, not entirely certain though.

I have blanked the IP addresses out for obvious reasons.
