Not recommended. Like Todd said, better setup bridges manually,
something like
http://wiki.debian.org/BridgeNetworkConnections#A.2BAC8-etc.2BAC8-network.2BAC8-interfaces_and_bridging
Create one bridge for each physical interface you need, with each
bridge (obviously) have one physical interface on "bridge_ports" line

Duh. Your brctl shows the bridge name is eth0, not xenbr0 :P
Some explanations on vif line:
vif = [
'mac=00:16:5e:72:04:01,bridge=xenbr0,script=your_custom_script1',
'mac=00:16:5e:72:04:02,bridge=xenbr1,script=your_custom_script2'
]
(1) note the two lines quoted by single quote? That means you're
creating two NICs for domU.
(2) "mac" is what you want that particular domU NIC's mac to be
(3) "bridge" is the name of the bridge on dom0 that the NIC will be attached to
(4) "script" is the script name that will be used to setup the NIC on
dom0. Usually you can just remove this section, as the default
vif-bridge script should work just fine.
Also try "xm create --help_config", and look for "vif=". That would
show all available options for vif line.
