As a new strategic to move people out of windows, i am using virtualbox as a replacement for old applications that only works on windows. So I use an unattended method to install those vboxes.
A few weeks back I found a problem when enable extra funcions (add-ons) for an smooth use of the machine. and i was 100% that the problem was on virtualbox software, but I could not know how to present it for the development teams to have a look.
My surprise was today that someone using same software reported the problem a month ago and today the fix was release con the 3.0.8 version.
Love open source!
