I'm looking to test VirtualBox 5.0 release or 5.0.x latest development stable build and get this error:
The Please try reinstalling VirtualBox. advice doesn't help.
I am guessing this is what happens when software designed to write files to the new protected system area on El Capitan (SIP/System Integrity Protection) is run, but I don't see any Apple Documentation explaining how to interact with apps or disable that new feature.
