I was wondering if anyone can point me to any specific documentation on how
to setup xen with dhcp.  For instance I have a server with Xen installed on
my network.  The internal IP address is   172.27.170.110, is there a way to
assign my vps's with similar IP's?

The guests will by default use a bridge connection and dhcp by default assuming they are configured as such.

If that is not happening, make sure are using the network-bridge script in your xend-config.sxp, you can also explicitly tell the guest to use dhcp in the config file by setting the dhcp parameter to dhcp (dhcp="dhcp") explicitly.
