[Grml] VM issues

Hi all, I've recently tried to install grml with parallels (on a macintel), and my attempt was unsuccessful, it might be a problem with parallels, but I was wondering wether anyone reported issues with that configuration? PS : I have installed a fedora on my external HD since then, but I don't like it as much. And grml saved my professional life once, thank you for your nice distro. BTW, I will provide more info if necessary.
