The default configuration for networking with Xen DomUs is bridging the network interface to the Dom0. This will make a DomU network interface appear on the LAN just like any other machine.
This HOWTO explains how you can change the configuration to masquerade all the network interfaces of the DomUs behind the Dom0. This will turn the Dom0 into a NAT box, which may be useful if you want to build a cluster that doesn't expose itself to the network.
