I'm using Xen 4.1 and here's what I did:
1.comment network-script and vif-script about bridge in /etc/xen/xend-config.sxp, uncomment the lines about nat
2.set vm config, add something like vif = [ 'mac=00:16:3e:00:00:11, ip=10.0.0.1' ]
3.set /etc/network/interfaces in domU, add lines as follows:
auto eth0
iface eth0 inet static 
address 10.0.0.1 
gateway 10.0.0.254 
netmask 255.255.255.0

But it didn't work!

Here's the output of "ifconfig -a" in dom0

tap10.0   Link encap:Ethernet  HWaddr a6:8a:1b:92:be:af  
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:500 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

vif10.0   Link encap:Ethernet  HWaddr fe:ff:ff:ff:ff:ff  
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:32 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

the vif10.0 didn't get an ip!
The same thing happened in domU whose eth0 didn't get ip, too. Strangely, eth0 was renamed to eth9, I don't know why.

So, where did I make mistake? How to setup NAT network in the new toolstack?

By the way, can I use bridge mode if I have only one IP?
