**** See my revision on Windows CAL requirement for 2008 Servers HERE******
Sticking to the theme of “Virtualisation” I thought I would cover off Server Virtualisation licensing
This I want to split into 2 clear area’s – Server OS Virtualisation and Server Application Virtualisation, a good licensing story for both!
Lets begin with the Server Operating System
The launch of Windows Server 2008 to Volume Licensing price list on 1st March 2008 brings with it some new licensing changes FOR THE BETTER!!
Lets be clear, we license on RUNNING instances, defined below in the notes section, NOT created or stored images, you may create and store any number of instances that you want, you can even create and store on a VHD/CD or DVD if you really want to, we made this change in December 2005 in case you missed it!!
To run an instance of Microsoft’s server software on your server, you must first assign a license to the server. By assigning a license to the server, you designate that server for use of the software and may run the software on that server. The number of instances you may run under one license depends on the Windows Server product you license. You can reassign server software licenses from one server to another, but not more often than every 90 days. There are some exceptions to this rule outlined in the Product Use Rights document. For example, you may reassign the license earlier than 90 days if you must retire the licensed server due to permanent hardware failure
So back to Windows 2008 Server, firstly the evolution of technology, then to the licensing,
With the initial release of Windows Server we will offer “Without Hyper Visor” within 6months, we will see on the price lists a choice of With or Without Hyper V

• You must license all the PHYSICAL processors in the box to permit unlimited Virtualisation rights
• Datacenter edition also requires Windows CALs
Note: Windows Web Server Step Up to Windows Server Standard Now Available: We will now be offering SA Step Up SKUs from Windows Web Server to Windows Server Standard (with and without Hyper-V) in all Volume Licensing Programs.
Server Virtualisation its so simple even a child can get it, check out this rather amusing video below
Use the Virtualisation Calcuator to work out your Windows License count
There is a NEW Activation process for Windows 2008 Server, KMS and MAK, check this out here
You run an instance of software by loading it into memory and executing one or more of its instructions. Once running, an instance is considered to be running (whether or not its instructions continue to execute) until it is removed from memory.
Instances cannot be split out across multiple servers, but, you may assign more than 1 license to a single server providing additional running instances
I will discuss licensing moving instances in a future blog
