Normally you would want to be using the same network setup. So when 
specifying the VIF entry for the new VM, specify the same xenbr0.
It may help to take a step back and consider what all this 
represents. The bridge is analogous to a physical switch. The VM is 
analogous to a physical box. And if you don't do anything special in 
the Dom0 then that isn't really analogous to anything - but if doing 
NAT, then it's analogous to a standalone router doing NAT.
So having got your standalone router doing NAT, and a physical switch 
allowing devices to be connected to it, you can connect multiple 
servers to that same switch. In the same way, once you've got the 
Dom0 with NAT and a bridge running, you can connect multiple VMs to 
the one bridge.
