Verified in Trusty in live environment via Trusty. The message is largely innocuous, as I've seen this in every version of VirtualBox available in a Ubuntu host, with every version of Ubuntu as a guest since Maverick. It would be nice if the message either wouldn't appear at all during boot, or whatever it's complaining about is dealt with.
