                  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.
