VirtualBox

Preliminary notes:

1) The majority of code in the VirtualBox Open Source Edition (OSE) is

copyrighted by Oracle Corporation. This code is combined with third-party code

that was originally released under licenses which the Free Software Foundation

considers incompatible with the GPL, such as the Apache License 2.0, the OpenSSL

license, the Mozilla Public License (MPL) and the Slirp license. (Please see the

VirtualBox User Manual for a complete list of third-party code and their

licenses.) As a special exception to the terms and conditions of the GPL listed

below, Oracle gives you explicit permission to combine its GPL code contained in

VirtualBox OSE with third-party code under the aforementioned licenses. You may

copy and distribute such a combination provided that you adhere to the terms and

conditions of all of the GPL and the licenses of the third-party code; in

particular, you must include the source code of the entire combination insofar

as the GPL requires distribution of source code.

2) The GPL listed below does not bind software which uses VirtualBox services by

merely linking to VirtualBox libraries so long as all VirtualBox interfaces used

by that software are multi-licensed. A VirtualBox interface is deemed

multi-licensed if it is declared in a VirtualBox header file that is licensed

under both the GPL version 2 (below) *and* the Common Development and

Distribution License Version 1.0 (CDDL), as it comes in the "COPYING.CDDL" file.

In other words, calling such a multi-licensed interface is merely considered

normal use of VirtualBox and does not turn the calling code into a derived work

of VirtualBox. In particular, this applies to code that wants to extend

VirtualBox by way of the Extension Pack mechanism declared in the ExtPack.h

header file.

3) Whoever creates or distributes a derived work based on VirtualBox OSE is not

obligated to grant the above exceptions for such a version. The GPL allows for

releasing a modified version without the above exception; in addition, Oracle

hereby also allows you to release a modified version which carries forward these

exceptions.
