Preliminary tests indicated that the latest version of VirtualBox is, for reasons unknown, not working properly under Win 7 64-bit.

So, I resorted to an older version (from last year) and it works fine. I did a quick test install of Win XP - it was very nice and easy. I might try several other OS as well.

It's not exactly everything that I had hoped for, but it's a good start. I will keep experimenting and learning :)
