Need some clarification on the following.
Datacenter Edition description lists:
Can be used as virtualization guest: Yes, unlimited virtual machines, plus one Hyper-V host per license
https://docs.microsoft.com/en-us/windows-server/get-started-19/editions-comparison-19
The way I understand it is, that I can create unlimited guest virtual machines without additional keys.
Is my understanding correct?
If not, please explain.
If yes, how do I go about creating guest virtual machines from the host's license?
This is not a general licensing question, more specifically regarding guest OS activation.
Windows VMs running on Datacenter are licensed through Automatic Virtual Machine Activation, which lets a VM activate via the Hyper-V service on the host.
All you need to do is to provision the VM with the appropriate AVMA product key, which are provided in Microsoft's documentation.
