I've found that configuring the bridges using the Red Hat method
(/etc/sysconfig/network-scripts) is easier and more straightforward than
finagling around in the Xen scripts.  Then you just disable Xen's method
with ``(network-script /bin/true)''.  The great thing about this is that
you can handle bonding, VLANs, and bridges all in the same spot and at
the same time.

Example bridge interface /etc/sysconfig/network-scripts/ifcfg-xenbr0:

DEVICE=xenbr0
TYPE=Bridge
BOOTPROTO=none
NETWORK=192.168.0.0
NETMASK=255.255.255.0
IPADDR=192.168.0.1
ONBOOT=yes
DELAY=0
STP=on

Example bridge port interface /etc/sysconfig/network-scripts/ifcfg-eth0:

DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
USERCTL=no
BRIDGE=xenbr0

Maybe your shebang is busted?
