====== Install VirtualBox Guest Additions ======
----

Launch your VBox VM from the VM VirtualBox Manager's main interface.

From the VM's window, select menu **Devices > Insert Guest Additions CD image...**\\

In most Desktop Environments, the system will suggest to auto-run the installation program.

In command line environments, you'll have to mount the CD:
<code>
> mount /dev/cdrom /media/cdrom
mount:/dev/sr0 is write-protected, mounting read-only
</code>

Then install the necessary packages:
<code>
> sudo apt-get install linux-headers-$(uname -r)
> sudo apt-get install build-essential linux-headers-`uname -r` dkms
> sudo /media/cdrom/VBoxLinuxAdditions.run
</code>
