Guest Additions is a feature of Virtual Box that allows you to install drivers on the guest OS to help integrate better with your host (XP) OS. Go to [IMPORTANT] http://download.virtualbox.org/virtualbox/ and choose your version number, probably ‘3.1.2′ and download the .iso file.
To install the guest additions, refer to the Virtual Box User Manual (F1). You will need to ’sudo apt-get install dkms’, mount and browse to the CD, and run the installer script. This will install several kernel modules, then you will need to restart the virtual machine. This will enable features such as host-guest file/folder sharing, and host-machine mouse integration. Highly reccomended.
