You shouldn't have to ifup the xenbr0 interface at all. There is also
no need to created sysconfig/network-scripts/ifcfg-xenbr0 either.

Just setup a normal 'ifcfg-eth0' configuration for networking in 
exactly the same way that you would for bare-metal. 

When the box comes up, eth0 gets configured as normal.

Then, when 'xend' starts it creates the xenbr0 device automatically
and makes eth0 part of the bridge & copies across the IP address
config that eth0 had to the bridge. You should never have to configure
anything on the bridge directly - should be all automatic.

Regards,
Dan.
