with a MAC address entry in the domU configuration file it would
also be possible to find the IP address in the arp table with the
command:

arp -n

on dom0 if you don't want to add each domU to the dhcp configuration.

You should also have a look at the tool "arpwatch". It sends you a mail
if a new address appears.

Maybe this works only in a routed xen network ...

This doesn't work on my routed setup

arp -n
Address                  HWtype HWaddress           Flags Mask            Iface
192.168.1.3              ether   00:09:5B:E6:3E:79   C                     eth0
192.168.1.1              ether   00:A0:C5:9B:AE:1D   C                     eth0
192.168.1.240            *       *                   MP                    eth0

The ip 192.168.1.240 is of a domU and the HWaddress has a * in it.
