A little background for you, the purpose of network-bridge is to start
bridged networking when xend starts and take it down when xend stops.
Its a creature comfort that allows you to use Xen on your desktop
without going though the hassle of modifying / restoring your system
network configuration every time you want to use Xen.

In a production (server) environment, its much much better to just allow
your operating system to control networking. network-bridge is not smart
enough to deal with complex configurations.

To take network-bridge out of the picture, try this:

cat << EOF > /etc/xen/scripts/network-dummy

exit 0

chmod +x /etc/xen/network-dummy

Check to be sure that the file is not already there prior to creating

Then, edit /etc/xend-config.sxp , look for:

(network-script network-bridge)

Change it to:

(network-script network-dummy)

At this point, xend will not try to do anything to networking when it
starts. You can then configure the bond / bridge via whatever means is
sensible for your OS.

If you let us know what OS you are using, someone can help you with that
part too.
