- No, if you already licensed the host/hardware with 2012 R2 Datacenter there wouldn´t be a need to license the VMs again. The licensing rights that applies are for the 2012 Datacenter edition which allowes you through downgrade rights to install previous version of standard and datacenter editions. You are not allowed to use the rights for 2008 editions if you have a higher edition installed on the host.
"What happens if I licence the host with a 2012 Datacentre licence and has the operating system as Datacentre, but my virtual machines are windows Server 2008 R2 Standard (the virtual machines are the hosts of the Microsoft desktop application software such Office, Project, Visio and Access) and my RDS are 2008? Would that be allowed, or would I have to allocate 2012 RDS CALS?"
- According to the Microsoft brief ("Licensing Windows Server 2012 R2 Remote Desktop Services" page 2) you need the 2012 RDS CAL to access the systems.
I hope this brings som clarity and at least answer some of your thoughts.

Hi OP, great question.
I've asked one of our Microsoft experts to answer for you.
You are not permitted to mix Datacentre and Standard licenses on the same server. All of the processors on a given server must be licensed with the same version and edition however you can run different editions or older versions of Windows Server software as guests within virtual operating system environment , but you are not allowed to assign multiple licenses of different versions or editions to the same physical server to license the processors on the server.

I am not sure it’s not allowed to double-license a Server with a mix of Datacenter and Standard – let’s assume you have a Windows Server 2008 R2 Datacenter license covering you for unlimited VM’s and you want to add a VM running 2012 Standard – you would be allowed to license that host again (provided you license all physical processors) with a Windows Server 2012 Standard Proc license. (1 license covering 2 procs, assuming 2 procs on the server)
In most cases however if you have a current version of datacentre double-licensing would not make sense as you get rights to prior versions and different editions.
With regards to the question of whether RDS 2012 CALs are needed I would challenge Microsoft on that – if you are not using RDS 2012 and are only running 2012 on the physical OSE and that physical OSE is not accessed, you might be able to get away with 2008 RDS CALs. The reason for this is that
…….if you have a server running an instance of Windows Server 2012 R2 in a physical OSE, you need a Windows Server 2012 R2 CAL to access that instance, except in the case where that instance is being used solely to :
Run hardware virtualization software
Provide hardware virtualization services
Run software to manage and service OSEs on the licensed server
Whilst this is from the Server License VL Brief focussing on WS CALs (not RDS) the License Model Terms for Processor Licenses in the Product Terms state that CALs are not required for access in a Physical OSE used solely for hosting and managing Virtual OSEs.
So unless you are using 2012 RDS Technology in my view your 2008 RDS CALs may suffice if you only access WS 2008 R2 in the VM’s using RDS 2008. I’d double check with your Microsoft Licensing Specialist.
