Quite agree Colarado Marmot.
I was able to download and install Lion in Guest VM but after OS install, when Migration Assistant choice was offered and activated it could not ‘see’ the connected external drive carrying a bootable clone of the original Lion OX. So I ticked ‘later’, continued the installation figuring once the OS was working I had Migration Assistant plus network or CCC install options. It is probable I was connected by USB 3.0 so I shall trash current Guest and reinstall Lion via OSX and USB 2.0. and try again.
