Both are true.  I use it heavily for running multiple Linuxes inside 
Linux.  Beautiful system, Xen.

Such is the theory behind virtualization.:)  Yes.

One method which _might_ work, is to setup a guest image which simply 
contains the installation CD.  Boot it with what you need to get it into 
text mode, and start a xen console on it, and you just might be able to 
use the installer to install on to a virtually exported hard drive 
partition, which you could later boot as its own guest.

I think that some such scheme is described in the Xen user's Manual, 
although it's been a couple years since I read that thing.

A tip for using Xen and Linux virtualization in general: LVM2 is a near 
must, if you're doing anything speculative.  Yes, you can use loop file 
systems, and probably want to for the installer that we're talking about 
here, but they are said to be slow for routine use, and I have no reason 
to doubt that.
