Comment 2 for bug 703816

I'm running VirtualBox4

I checked in the manual and all the commands used inside testdrive are unchanged.

I started to update the code for the version check (now the version is stored in a tuple of two ints instead of a string, so it's a little bit cleaner) to try to run it with VirtualBox4

from my test everything is working

I've linked the branch with my small little changes, if someone can review and merge it we can clear this bug :)
