Hi *

Before putting my hands on the subject, thought on asking b4 to not waist time.

Imagine the following situation.
You want to give a tutorial about virtualization to a couple of students (or people in the lab wanting to learn), and do not want them to screw up your dom0.

My idea was to create a domU with enough resources (say, 6 vcpu's and 2 GB RAM per vcpu).
Then, I can give to the students the root passwd for this domU, and they can start to build some VM's inside of it.
Is this idea feasible?

I've not set it up yet but I'd been wanting to do this before with my classes and the answer I got was to create all the initial DomUs for the students as HVM. Then you can put PV DomUs inside it. Like I said I haven't tried it but people in the know said it was possible.

You will of course need to have the correct VT hardware to do HVM on your machine.

Some people, when confronted with a problem, think "I know, I'll use Windows."
Now they have two problems.
