Virtualbox

When I was setting up virtual box I had to add myself to the group vboxdrv or something like that as well as give myself read write privileges to to the folder /dev/vboxdrv/. I also under super user used the command "modprobe vboxdrv" which has been suggested that users add to the file /etc/modprobe.conf.local so you don't have to enter the command every time you boot.
