The importance of licensing with regards to virtualization.

Concerning licensing and virtualization – the most important thing to know is that any guest operating system must have a license, just as any physical server or workstation does. Thus, if you run Microsoft Virtual Server on Windows Server 2003 and 3 guest operating systems are running (Windows XP, Windows Server 2008, and Windows Vista), you must have 4 Microsoft operating system licenses – Windows XP, Windows Vista, Windows Server 2003, and Windows Server 2008.

As Linux is typically open source, you can generally have as many Linux guest operating systems as you want without paying any licensing fees. Just make sure you following the license agreement for your operating system.
