Short answer: don't bother. Just use distro-bundled Xen, and if
there's a problem people using the same distro can help you.

Long answer:
Newer version of Xen won't have xenbr0. This is normal. The bridge
will be eth0 (or whatever your primary network device is). What is the
output of "brctl show"?

Also, the current recommended way to setup bridge is to use your
distro's mechanism (e.g. /etc/network/interfaces,
/etc/sysconfig/network-scripts/*), so you shouldn't use network-bridge
