I have the same issue using a Oneiric 20110530 Live CD in VirtualBox 4.0.8. It boots normally and shows the standard Ubuntu wallpaper for a second, but then it only shows a "blue screen" (reminds me of a certain company *duh*). I even tried to enable 3D support in Virtual Box, same issue. No error or menu shows up. I have added a screenshot to show what it looks like.
