Okay, I should probably have read a little more between the lines from
your previous posts and just assumed that all you wanted to do was to
have you DomU interfaces bridged with eth0 on Dom0. You don't care 
about eth1 or eth2 for the moment right?

Well, if that is what you want, the main problem you've got at the
moment is that there are two bridges and one of them doesn't even seem
to really exist. I honestly don't have a clue how this could happen, but
I can suggest something for you to try.

In the file /etc/xen/xend-config.sxp, change:

    (network-script network-bridge)

to 

    (network-script 'network-bridge bridge=xenbr0 netdev=eth0')

Reboot your server to give it a fresh start. Then check 'ifconfig' and 
also 'brctl show' to see that there is only the one bridge, xenbr0. If 
all looks well, then try to start a DomU.

cheers
