Server Virtualisation Part 1 – Server Operating System Licensing – Windows 2008 with/without Hyper V

 **** 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

More info on Matt’s Blog

 

 

 

Licensing of Windows Server 2008 by Edition

Windows Server 2008 Standard  – Licensed by Server and CAL mode

• One License = 1 running instance in 1 Physical OSE AND 1 running Virtual OSE on the server, create and store unlimited non-running instances

Windows Server 2008 Enterprise  – Licensed by Server and CAL mode

• One license = 1 running instance in 1 Physical OSE AND up to 4 running Virtual OSE on the server, create and store unlimited non-running instances

• The Physical OSE must be Enterprise edition or a 3rd party technology, the virtual OSE can be Enterprise or Standard or a prior version

Windows Server 2008 Datacenter  – Licensed by Proc and CAL mode

• One license = 1 running instance in 1 Physical OSE AND unlimited running Virtual OSEs on the server

• 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

Note:

We made Windows Server 2008 available to our Software Assurance customers for Download on 15th Feb 2008  on eOpen and MVLS

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

  1. Two questions:
    1) Can I assign for example TWO licenses to a physical host, so I use 8 instances in VMs?
    2) What about SBS 2003 R2 and WinSB R2? For WS2003STD we show 1* + 1, here we show 1* or 1. What does that mean? That if I install SBS on host, – no VMs? But I can isntall it in VM if I didn\’t assign it to host?
     
    Sincerely, Alex

  2. Hi Alex
     

    1) Absolutely, you can stack the licenses to fulfil your requirements
     
    2) SBS is 1 running instance in a physcial host OR a virtual host, so you choose the deployment, if you install on a physcial host and then create a virtual running OS instance, that needs an additional license, so you dont get any "free" Virtual OSs
     
    Windows Server 2003 R2 Std is the same as SBS above, 1 or 1
    Windows Server 2008 Std is now 1 + 1, so you get 1 Physical OS instance AND 1 Virtual OS instance
     
    Hope this helps

  3. Thank you for great answers!
     

     
    There is one more term,  mostly confusing "my fragile little mind"  🙂
    That is about asterik in virtualization rights for OSes (1* + 4) for WS2008 Enterprise for example. 1* means, that if I use 4 free VM instances, then the host can be only used to support VMs. But can I install network roles on that? Active Directory? DHCP? WINS? DNS? File Server?…
    The one included in OS. Of course my VMs will use it. But not only VMs of course. Is that allowed?

  4. Hi Alex
     
    When you take advantage of the full extended virtual rights, so in the case of Windows 2008 EE, You install 1 Host and Guest OSs, the Host can only be used to "manage" the virtual/guest OSs, so you should not have a server application installed on there, like Exchange/SQL etc
     
    Provided that you use the host solely for management, there should be no licensing issues

    This is primarily a customer blog, most customers will not require the level of detail below
     
    My suggestion is we take this offline, so please email me from the GAL
     
    Really you should be working with the incountry licensing team to provide you this level of assistance below to go back to your customers
     
    Cheers

  6. Just out of interest does it matter what the host server software is?  So for example if you are using VMware and you purchase a copy of 2008 Enterprise can you run 4 virtual hosts on this server and be covered by the one license you purchased?
     
    Thanks for taking the time to list this.

  7. Hi there
     
    My question is around Datacenter and licences for desktop OS\’s.  We have 4 processor servers running around 50 XP desktop machines each.  I assume we can\’t buy 4 x datacenter licences to cover the desktop OS\’s – so what is the most effective of licensing in this example?  (The servers are using 3rd party bare metal virtualisation software).
     
    Thanks

  8. I\’ll start with a scenario then ask the question.I buy a server say with win2k8EE OEM, however I install SUSE (Linux) Enterprise as the host OS. Would I be able to run 5 VMs as the host is not Windows 2k8? Just for clarification on a question Alex asked are Active Directory, DHCP, WINS, DNS and File Server considered "applications" of the same ilk as Exchange/SQL etc and does the same rule apply to Non-MS hosts e.g. I cannot install DHCP, MySQL, Apache i.e. the SUSE host is there to only manage the VMs.RgdsGlen GreavesDevelopment Support Manager

    Answer:
    MS or 3rd party technology is supported on the Host, so if you purchase WinSvr2008 EE, your choice for Host is EE or 3rd party technology + 4 Virtual OSs

    My question is around Datacenter and licences for desktop OS\’s.  We have 4 processor servers running around 50 XP desktop machines each.  I assume we can\’t buy 4 x datacenter licences to cover the desktop OS\’s – so what is the most effective of licensing in this example?  (The servers are using 3rd party bare metal virtualisation software).
    Answer:
    Correct, Server OS will not cover Desktop OS installs
    If you have Windows Vista Business AND software Assurance, this will provide remote boot rights, you can install/store and create unlimited copies of Windows Vista Business or Windows XP Pro on a server and permit your licensed device to connect up <remote boot> we have also taken this a step further with VECD, see blog entry on this, Windows Vista Business + SA + VECD subscription permits unlimited running instances on servers <SAN/NAS>  connection via PC or Thin Client
    If you have XP Pro licenses purchased via OEM they are tied to the original hardware they were first installed onto and cannot be installed or accessed via a server, retail XP Pro is a 1:1, so if you have 500 XP Pro PCs connecting to 500 instances of XP Pro on a Server, you need 500 XP Pro for the devices AND 500 FPP copies of XP Pro for the server, SA and VECD removes all this
     
    The cheapest most cost effective way is to attach SA when you have good hardware and use remote boot, if the hardware is poor, then VECD is the best route
    Cheers Emma

  11. Hi Glenn
     
    Q1 – No, you do not get an additonal VM if you choose to use alternative technology on the Host, its 4VMs for Win2008EE
     
    Q2 –  You may use ANY software – including 3d party and our server software on host, if it is used “to manage and service” both host and my 4 free VMs instances.
    That counts AD DS on host (for VMs), SQL for System Center, VMware Virtual Center, etc…
    You can’t use any of it to manage other hosts or VMs.
    Cheers Emma

  12. Hi Emma
     
    I have one more question. What did you mean saying that "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"?
     
    Is it true that we cannot buy full (i.e. "with Hyper-V") editions now? Are there currently only "without Hyper-V" in stock?
     
    I thought we can buy any edition today. Sure, we would not actually get Hyper-V even if we bought the "full" package today. But if we did, we could simply install Hyper-V on top — when it is released. Also, if we bought "w/o Hyper-V" today, we would not be able to install Hyper-V even when it is released.
     
    Thanks in advance
    Artem

  13. Hi Artem
     
    When I wrote the post the only option, so March 1st, was Windows Server WITHOUT Hyper-V, the plan was to eventually have WITH Hyper-V SKUs on the volume licensing pricelist within 6months
      
    You should purchase without Hyper V if you want to deploy using non-MS virtualisation technology
     
    Hyper V is available as a stand-alone offering also same as Virtual Server
     
    Customers who were on active Software Assurance on Windows Server 2008 release had the choice of moving to with or without, once they decide, its a permanent choice
     
    More on Without Hyper V
     
    “Without Hyper-V” licenses
    Although the new Hyper-V hypervisor technology is a key feature of the Windows Server 2008 core operating system, Microsoft will still provide customers the choice of deploying Windows Server 2008 without this technology. Microsoft will enable this by offering Windows Server 2008 Standard, Enterprise, and Datacenter licenses without Hyper-V at a slightly reduced price from their regular license counterparts. The licensing terms are exactly the same as their Standard, Enterprise, and Datacenter edition counterparts, including the virtualization use rights. With Windows Server 2008 Standard, Enterprise, and Datacenter licenses without Hyper-V, a customer will need to separately license the hypervisor technology, whether it is Hyper-V, Microsoft’s Virtual Server R2, or a third party hypervisor technology.
     
     
    CheersEmma

  14. Thanks Emma
     
    So as far as I understand, if I have Windows Server 2003 + SA and want to move to 2008, I have to chose between "full" edition and "without Hyper-V". After I make this choice I can\’t change it. Correct?

  15. Mike DA customer asked me yesterday if they needed Windows Server 2008 CALs for a Hyper-V host. I said check with your Microsoft person but I didn\’t think so since people were using the VMs and not the actual host. Then I got to thinking about CALs. CALs are required for using the services of a host. The Hyper-V role is just like DHCP or DNS or the other standard roles in Windows Server 2008. Those other roles need CALs don\’t they? If so does that mean you do need CALs for the host?Hi Mike, unable to email you, so next best thingThe highest server version will set the CAL version requirement, so Windows Server 2008 Host, 2003 Virtual OSEs, 2008 CALs are required for any services of server, directly or indirectly, and of course all autenticated devices/users, just a note on this, this info is true for Windows Server with or without Hyper V, we also have an additonal offering of Hyper V standalone, which requires no CALs but does not have all the technical advances of Windows Server with Hyper V, it is suited to smaller non enterprise customers for VDI solutionsHope this HelpsEmma
