So the combination works now? Good to know. Previously RHEL/Centos
kernel does not work with Xen 4.0.0.

The biggest difference that I can think of moving from the stock
Centos Xen to Xen 4.0.x is that it'll be possible (or at least easier)
to work with some types of PV domUs (like Ubuntu and Opensolaris).
However you'd need a new dom0 kernel if you also want to try out newer
features like blktap2.

For common purposes though, I highly recommend to just stick with your
current setup, using stock Centos kernel-xen.

It's not there. The networking setup changed so the bridge is called eth0 now.

Just change all reference of "xenbr0" to "eth0" on domU's config file
(or don't specify a bridge name), and you should be fine.
