Licensing and Hyper-V VM Guests

Hi!

I have a project where we will have a server (2x Intel Xeon Silver 4208 = 2x 8 cores) with Windows 2019 Standard Server. The client wants to install all of the services in a VM guest.

The server seller told us that with Windows 2019 Standard Server we can have 2 virtual machines for free. The virtual guest will also run Windows 2019 Standard.

Is the VM guest license also covered? or should we purchase one more Windows 2019 Standard Server license?


Thank you in advance!

Shouldn't be a problem, some general info

  • Each host needs to be licensed.

  • A minimum of 8 core licenses is required for each physical processor and a minimum of 16 core licenses is required for each server.

  • Core licenses are sold in packs of two.

  • Standard Edition provides rights for up to 2 Operating System Environments or Windows Servers containers with Hyper-V isolation when all physical cores in the server are licensed. For each additional 1 or 2 VMs, all the physical cores in the server must be licensed again.

  • DataCenter Edition provides rights for unlimited Operating System Environments or Windows Servers containers with Hyper-V isolation when all physical cores in the server are licensed.

...and in case it isn't 100% clear by now: With your first Standard lincense, you only get two VMs if the OS that is installed on the host does not run any workloads other than Hyper-V and management agents like monitoring, backup or AV. If any user or device has a reason to connect to tha host (other than to manage said host), the first license is consumed by that and you can only run ONE VM until you add another Standard license for every physical core.

Thank you all for the quick response!

I ony need 1 VM guest (OSE?). That guest will use all of the CPU cores with a constant workload of about 50%-60% for video processing.

That software has a client - server architecture. Multiple clients may connect to the video server.

So if I understand correctly it's covered by the physical host's license. Please correct me if I'm wrong.

One more question that just occurred to me is what key should I use in the VM?


Please, forgive my ignorance about MS terminology I'm returning from the Windows 2012 era! :D

Yes, that's correct.

Use the same key as used on host.

If your host machine is running DataCenter, and fully licensed, can you also run Guests with DataCenter and have them covered by the parent?
