I have the official Sun Virtualbox installed for private use, but this should work for OSE with little or no modification.
1. Open CompizConfig Settings Manager.
2. Scroll to or select Window Managment.
3. Open the Window Rules options.
4. Add the following in the No ARGB Visuals box (without the quotes): "title=- Sun VirtualBox$"
5. Check the Enable Window Rules box if necessary.
If there are already rules in this block, you should add an or pipe (|) before the title specification.
