I bout one especially for the job (I planned to use xen, but never mind) 
and installed a 320 Gb disk.

I made one big partition, and use files for emulated disk. Reputedly 
this is less efficient than using real disks, but performance isn't an 
issue. It's for evaluation, learning and testing techniques.

I would suggest that running any sort of workload on the host separate 
from the guests isn't a good idea. Unless I've missed something, Linux 
sees each guest as just one more process and ranks each virtual machine 
about equal to Firefox, Seamonkey, Thunderbird etc,

One thing to take note of, lots of RAM. You need real RAM for each 
guest, you cannot overcommit.

Discussion seems to be on the fedora xen list.
