I'm using Xen 3.0.2 on Debian etch and my config is:

-------------------------------/etc/network/interfaces:--------------------------------------------------

iface lo inet loopback

auto br-xen-tg3
iface br-xen-tg3 inet static
      address 10.0.100.1
      netmask 255.0.0.0
      network 10.255.255.255
      bridge_ports eth-tg3


------and so on (I've renamed the network interfaces from eth0, etc to
the drivers name using udev)--------
My www called DomUs config is looking like:
------------------------------------------------------------------------------------------------------------

kernel = "/boot/vmlinuz-2.6.16-1-xen-686"
ramdisk = "/boot/initrd.img-2.6.16-1-xen-686"
memory = 128
name = "www"
vif = [ 'mac=00:00:00:00:00:04, bridge=br-xen-tg3' ]
disk = [ 'phy:/dev/DomU/www_root,0x301,w',
'phy:/dev/DomU/www_swap,0x302,w' ]
root = "/dev/hda1 ro"
extra = "2"


--------------------------------------------------------------------------------------------------------------
With Xen 3.0.2 Debian packages I didn't need to thinker with the xen
scripts any more, since the network bridge configuration happens right
at the network startup.

Good Luck!

Geza
