My curent setup is similar to what you trying to get. I have:
gw:/home/bdew# ip link
1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
link/ether 00:07:95:36:e6:ad brd ff:ff:ff:ff:ff:ff
3: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
link/ether 00:10:4b:2e:ac:17 brd ff:ff:ff:ff:ff:ff
4: br-exp: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue
link/ether fe:ff:ff:ff:ff:ff brd ff:ff:ff:ff:ff:ff
5: ppp0: <POINTOPOINT,MULTICAST,NOARP,UP> mtu 1460 qdisc pfifo_fast
link/ppp
6: vif1.0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue
link/ether fe:ff:ff:ff:ff:ff brd ff:ff:ff:ff:ff:ff
7: vif2.0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue
link/ether fe:ff:ff:ff:ff:ff brd ff:ff:ff:ff:ff:ff
eth0 and eth1 are phisical cards connected to real networks.
ppp0 is an l2tp link running thru eth1.
vif1.0 and vif2.0 are created by xen scripts and connected to eth0 in 2
domains, they are assigned to br-exp and not used anywhere else.
br-exp is a (bridge) virtual interface connect to both domu's.
Routing looks like this:
172.28.0.0/19 dev eth1 proto kernel scope link src 172.28.29.156
10.0.0.0/16 dev eth0 proto kernel scope link src 10.0.0.1
10.1.0.0/16 dev br-exp proto kernel scope link src 10.1.0.1
default via 212.143.208.155 dev ppp0
The domU's have adresses from 10.1.x.x subnet, and use 10.1.0.1 (br-exp)
as their default gateway.
The computers on eth0 network have their netmask set to 255.255.0.0, and
adresses from 10.0.x.x, 10.0.0.1 being the default gateway.
Infact this is a routed setup (no direct conection between domU's and
real networks), but it uses xen in bridged mode to consolidate all vif's
to 1 interface.
