A warning to (Windows) users

I have received some reports about troubles loading the images. Here are some things you may want to try (please, please, please let me know if they worked):

• Use the latest version of VirtualBox available. Don’t stick with older releases if you can upgrade.
• If you are using Windows, using the .xml virtual machine descriptor I provide seems pretty impossible. Re-creating the virtual machine through the VirtualBox wizard after having registered the hard disk image seems to help a bit.

I haven’t access to a Windows machine for testing. I need reports from you to try to find a fix to those annoying troubles.
