That makes complete sense, if I controlled the dhcp. Unfortunately, in
this case I don't control the dhcp server configuration.

I was looking for a way to determine the ip of a domU from the command
line of the dom0. I found that with 'xm list --long <domid>' I could see
some of the information that dhcp sets like gateway and netmask in the
section seen below, but the ip is always literally '1.2.3.4'. Seems like
a bug in xm.

            (ip :1.2.3.4:10.25.7.1:255.255.255.0:vm1:eth0:dhcp)
            (root '/dev/sda1 ro')
            (args 4)
        )
    )
