A few options...
. You could get the machine to publish it's IP in xentstore
. use something like arpwatch in the logs of Dom0 and then grep for the
IP address
. examine the DHCP lease database
. use tcpdump with an 'ether src <mac of client>' filter
. nmap -sP <subnet> and then examine the arp cache
