I am using the latest edition of Virtualbox 4.1.12 and I get the attached when I attempt to launch Unity. Everything is running in the background but it's not displaying the launcher, dash, or panel. Just a long line at the top of the screen.

I've tried to reboot the VM as well as ensure all updates are installed. I've also tried removing and reinstalling the Guest Additions. See screenshot below:

Please note that the possible duplicate does not describe the same problem. That fix is not appropriate as Unity is in this case actually running but not displaying properly.

Try unchecking the "Enable 3D acceleration" feature in Virtualbox under Settings --> Display. It worked for me.

You also need the extension pack to work properly http://download.virtualbox.org/virtualbox/4.1.12/Oracle_VM_VirtualBox_Extension_Pack-4.1.12-77245.vbox-extpack

I had the exact same problem and stumbled across this question while trying to figure it out. I managed to fix it by comparing it to a pre-configured distro I had already been running in order to use KDEnlive in Windows, which worked fine.

I noticed that 3D acceleration was unchecked on that, and that PAE/NX was enabled, so I made those changes and Unity shows up fine. It runs very slowly, but it shows up!

Hope this helps anyone who is still looking for the answer (or even the OP if he is still stumped by this) :)
