Not having done such a thing with xen, I can only say that you can do it with 
kvm, starting with a base image and making multiple copy on write (COW) machines 
which pretty much create instantly and take only as much disk space as the 
changed data. I would hope the xen tools would support a similar approach, but I 
can't tell you how to do it. Roll out of a name machine is five minutes or so, 
start the new VM with a fresh MAC address so your DHCP server gives it a unique 
IP, set the name and services and go.

I present this since you asked, not as a recommendation to do it the way I do...
