I just updated to VirtualBox 4.3.16 and now when putting my guest OS in fullscreen the Unity launcher stays over the top of the screen. This makes using full screen unworkable.
Disabling mini-toolbar in VMs settings is a temporary work-around. In the VirtualBox manager go to Settings->General->Advanced tab -> Mini ToolBar [] Show in Fullscreen/Seamless and make sure it is unchecked
It appears that this is a known issue with VirtualBox as reported on the VirtualBox forums. Presently there is no fix. Most users are rolling back to 4.3.14.
Same problem over here running Virtualbox 4.3.16 host on Windows7 and as client Ubuntu 14.04.1 (kernel 3.13.0-36-generic #63-Ubuntu SMP Wed Sep 3 21:30:45 UTC 2014 i686 i686 i686 GNU/Linux).
Found a reasonable workaround. Hit CONTROL-ALT-DELETE and make your choice to CANCEL. Guess itś related to X-server. Had it in the past with 12.04 or 12.10. Seems behavior is back again :-). Someone already raised a bugreport???
What also works is to minimize Ubuntu client when it's starting (booting). Maybe something with X-Server (X11) or the support for it on VirtualBox.
