Installing VirtualBox and extension packs
http://www.virtualbox.org/manual/ch01.html#intro-installing

VirtualBox comes in many different packages, and installation depends on your host operating system. If you have installed software before, installation should be straightforward: on each host platform, VirtualBox uses the installation method that is most common and easy to use. If you run into trouble or have special requirements, please refer to Chapter 2, Installation details for details about the various installation methods.

Starting with version 4.0, VirtualBox is split into several components.

1.

The base package consists of all open-source components and is licensed under the GNU General Public License V2.
2.

Additional extension packs can be downloaded which extend the functionality of the VirtualBox base package. Currently, Oracle provides the one extension pack, which can be found at http://www.virtualbox.org and provides the following added functionality:
1.

The virtual USB 2.0 (EHCI) device; see the section called “USB settings”.
2.

VirtualBox Remote Desktop Protocol (VRDP) support; see the section called “Remote display (VRDP support)”.
3.

Intel PXE boot ROM with support for the E1000 network card.

VirtualBox extension packages have a .vbox-extpack file name extension. To install an extension, simply double-click on the package file, and the VirtualBox Manager will guide you through the required steps.

To view the extension packs that are currently installed, please start the VirtualBox Manager (see the next section). From the "File" menu, please select "Preferences". In the window that shows up, go to the "Extensions" category which shows you the extensions which are currently installed and allows you to remove a package or add a new one.

Alternatively you can use VBoxManage on the command line: see the section called “VBoxManage extpack” for details.
