I as able to install the Fedora 7 guest OS just now. I'm at last seeing 
the light. I will reinstall Fedora 7 from scratch, this time doing a 
pretty minimal Xen system installation, then installing guest OS'es 
sized the way I want and with the applications I want. But it looks like 
I'll eventually need to buy a better processor and motherboard to get 
full virtualization.

Even so, this is pretty neat! I was just asking on the fedora-xen 
mailing list how to make the guest console bigger.

My typo, sorry.
