It's kinda difficult to explain most things if our knowledge of Linux in
general is lacking as most people don't want to have to give a Linux 101
course in this ML.  I would probably try to get accustomed to Linux in
general before taking on something like Xen.  Xen is a bit of an
"advanced" topic and right now I'm not sure if there are any/many
point-n-click solutions for it.

They are probably referring to a paravirtualized (PV) domU.  PV domains
use a patched version of the vanilla kernel that comes with most (Linux)
distributions, so a typical install-from-cd is not possible.  If you are
referring to full virtualization then it is possible *if* your hardware
supports it.

jailtime.org does have some pre-made images from some of the major Linux
distributions.  You can install onto hard drive partitions.  There is
documentation that explains this, but you do need to understand a little
Linux beforehand.  I'm sorry, but explaining from step 0 will simply
take ages (much longer than it took me to compose this email).
