In 06-install-grub.bash, your're using the grub package from the host to install grub in the VM's MBR, but with the new Ubuntu Natty, the default loader is now grub2 (with an horrible syntax :-), so as my host is using grub2, I can't install grub (apt-get asks me to remove grub2 to do this, which is something I don't want).
