Licensing FAQ

 This page deals with questions you may have about VirtualBox and its licensing.

- 2. '''What license is !VirtualBox released under?'''
+ 1. '''What license is !VirtualBox released under?'''
 
  The Open Source Edition (OSE) is released under the [wiki:"GPL" GNU General Public License V2]. Essentially, this means that you get the full source code of !VirtualBox OSE, and you can distribute and modify it, provided that you ship all modifications under the GPL as well.

  If you want the extra features that are missing from !VirtualBox OSE, you can alternatively use the full !VirtualBox package free of charge for personal use or evaluation purposes. Both versions -- !VirtualBox OSE and !VirtualBox -- are available from the [wiki:"Downloads"] page.

+ 2. '''Can I buy a commercial license for !VirtualBox?'''
 
  If you are an individual end user, there is generally no need to purchase a commercial license, provided that you respect, in the case of !VirtualBox OSE, the terms and conditions of the [wiki:"GPL"], or, in the case of the full !VirtualBox package, those of the [wiki:"VirtualBox PUEL" Personal Use and Evaluation License].

- 4. '''How can !VirtualBox be both open source and commercially licensed?'''
+ 3. '''How can !VirtualBox be both open source and commercially licensed?'''
 
  This is called "dual licensing". Since !InnoTek held all the copyrights to the !VirtualBox code, or is at least permitted to relicense code that is owned by external contributors or other parties, we are free to choose the terms under which we license the code to our customers, or the open source community. 
 
- 5. '''Why dual licensing?'''
+ 4. '''Why dual licensing?'''
 
  We -- like other companies -- believe that dual licensing gives both developers and users the best of two worlds. While anyone is free to look at the code and even improve it, commercial licenses support the company and allow for professional maintenance and support. The open source community gets more high-quality free software at no cost, while businesses can rely on quality support from our first-hand developers. Both worlds profit from each other: The commercial licenses support both our business and the open source community, and vice versa.
 
- 6. '''Will the licensing terms of !VirtualBox OSE be changed in the future?'''
+ 5. '''Will the licensing terms of !VirtualBox OSE be changed in the future?'''
 
  We are not currently planning to do so, but it doesn't really matter. Any code that was once released under the GPL cannot be "closed" again. The license that !InnoTek has granted you with the GPL is perpetual and cannot be taken back. Even if !InnoTek wanted to change the license again, this could only affect future versions, and anybody would still be permitted to redistribute the existing !VirtualBox code under the terms of the GPL.
 
- 7. '''What exactly is this ''personal use'' you talk about in the [wiki:"VirtualBox PUEL" Personal Use and Evaluation License]?'''
+ 6. '''What exactly is this ''personal use'' you talk about in the [wiki:"VirtualBox PUEL" Personal Use and Evaluation License]?'''
 
  Personal use is when you install the product on one or more PCs yourself and you make use of it (or even your friend, sister and grandmother). It doesn't matter whether you just use it for fun or run your multi-million dollar business with it. Also, if you install it on your work PC at some large company, this is still personal use. However, if you are an administrator and want to deploy it to the 500 desktops in your company, this would not qualify as ''personal use''. Well, you could ask each of your 500 employees to install !VirtualBox but don't you think we deserve some money in this case? We'd even assist you with any issue you might have.
 
- 8. '''What is your definition of ''academic use'' in the [wiki:"VirtualBox PUEL" Personal Use and Evaluation License]?'''
+ 7. '''What is your definition of ''academic use'' in the [wiki:"VirtualBox PUEL" Personal Use and Evaluation License]?'''
 
  Use at an academic institution such as schools, colleges and universities by both teachers and students is covered. So in addition to the personal use which is always permitted, academic institutions may also choose to roll out the software in an automated way to make it available to its students and personnel.

+ 8. '''Which guidelines apply to the use of the name ''!VirtualBox''?'''
 
  The term ''!VirtualBox'' has been registered by !InnoTek as a trademark. It may be freely used together with the products available from this web site. However, if you choose to ship custom binaries and/or source code revisions of the product, !InnoTek reserves the right to deny use of the trademark ''!VirtualBox''. This might seem rather strict but we believe that it is important to avoid any kind of confusion arising from multiple versions of the same product coming from different sources.
 
- 10. '''What about software patents?'''
+ 9. '''What about software patents?'''
 
  !InnoTek offers !VirtualBox free of charge to anyone who finds it useful. The only restrictions we impose are those of either the GPL or our respective commercial licenses -- whichever you choose. This also means that we will not restrict your use of the product by means of patents. However, should someone attempt to abuse the product, e.g. by violating the GPL or our commercial license, we will make use of our intellectual property rights to protect !VirtualBox.
