Here's an article that describes the process of setting up virtual systems on a Mandriva 2007 Spring system.
I haven't tried it myself, yet. But perhaps I'll have some time this weekend to give it a go.
Anyway, I just thought I'd mention it in case any Mandriva users here missed it.

This method uses VirtualBox, an open source system "virtualizer" (as described on innotek's webpage).
