Windows Server 2012 R2 Licensing
-
@Alket_tux said in windows server 2012 r2 licensing:
i just said that in figurative manner..
i have another question though.. if i run a windows machine in hypervisor, how is licensing applied?
The same, no change. Windows is licensed by the physical box that it runs on, not what the hypervisor presents to it.
However, you get two VMs when virtualized, per fully licensed Standard.

@Alket_tux said in windows server 2012 r2 licensing:
so i have a windows vm and i assign to it one processor, how do i pay for it's licence?
Processor assignment is not a factor for Windows licensing. Only actual, physical processors matter.
-
Example case:
Four processor server where you want to run one or two VMs: You need TWO Standard Licenses.
Four processor server where you want to run three or four VMs: You need FOUR Standard Licenses. -
@scottalanmiller said in windows server 2012 r2 licensing:
o VMs: You need TWO Standard Licenses.
so in the second case i need four licences
2 - for the 4 processor server
2- for the windows in the vm'sright?

Not quite. It's two for the first two VMs. Two more for the second two VMs. We could go on like this:
Four processor server where you want to run five or six VMs: You need SIX Standard Licenses.
Four processor server where you want to run seven or eight VMs: You need EIGHT Standard Licenses.
Four processor server where you want to run nine or ten VMs: You need TEN Standard Licenses.
Four processor server where you want to run eleven or twelve VMs: You need TWELVE Standard Licenses. -
There is no breakdown of "these licenses are for the processors and these are for the VMs." It's very simply that for every two VMs on the box, you must have the processors licensed.
-
There is a reason why, in the Windows world, four processor servers have mostly gone away. Two processor machines are the mainstay. While in the UNIX world, much larger servers are common.

@scottalanmiller now i get it. thanks a lot
-
No problem. Keep in mind that with Windows 2016, the additional complication of core licensing is being added. Windows 2012 R2 is simple by comparison.
-
@scottalanmiller yes i read that,, i am just a bit confused about the hyper v server core , and hyper v in windows server..
if i use Hyper v server core, how many licenses do i need, have you got a clue?

There is only one Hyper-V, and it is free. Always free, no matter what. Hyper-V has no licensing, there is no possible way to pay for Hyper-V.
If you use Windows to deploy Hyper-V, which you should never do because that's just bad practice and causes other problems, you have deployed Windows, obviously, and you must license that as usual.

@scottalanmiller yes i get that what i am asking is:
i have hyper v installed on my 4 processor server, on top of it i install a windows server 2012 r2 standart, i assign to it only one processor..
in this case i need only one licence ? -

Four processors, one VM = 2 Standard Licenses

@scottalanmiller so you are saying that it does not depend on the fact that the VM is virtualized,

Correct, there is only... how many VMs, how many processors. That's it. The amount of RAM, assigned vCPUs and such have nothing to do with Windows licensing. Virtualization is the only enterprise deployment method so all licensing is designed assuming that already, it's not a weird exception to normal licensing, it's the majority case.
-
The windows licenses apply to the physical machine, everytime you add another fully licensed copy of Server 2012r2 (2 Server 2012 Standard licenses in the case of 4 processors) you can legally run another 2 windows VMs.
If you only had two processors instead of 4, for every standard license you would get 2 vms, so if you bought two standard licenses you could run 4 vms legally.

@brianlittlejohn thanks, i have another question, if i install windows 2012 r2 standart on my bare metal server with 2 processors, and i enable hyper v as a role:
1- I need one licence as there are 2 processors ?
2- do i get to have 2 virtual machines (WS 2012 r2 Standart) for free? -

Under no conditions should you ever do this!!
All this does is make your system have more overhead, increase risk and make it harder to deal with in the future. There are no benefits but major problems. It's an anti-best practice and should be absolutely avoided.

Correct, but don't do it.
