To answer this question directly, yes, you do need a Windows license for each Hyper-V virtual machine (VM) running Windows as the guest operating system, as Microsoft requires a valid license for each instance of Windows, whether it’s running on a physical machine or a virtual machine. The licensing requirements for Hyper-V are based on the number of virtual machines running Windows Server or Windows client operating systems, and the type of license you have, such as Windows Server Standard or Datacenter edition.
Understanding Hyper-V Licensing
Hyper-V is a hypervisor developed by Microsoft that allows you to create and manage virtual machines. While Hyper-V itself is free to download and use, the guest operating systems running on the virtual machines require licenses.
Windows Licensing for Hyper-V
For Windows Server, you need to purchase a license for each physical processor on the host server, with a minimum of 8 core licenses required for each processor and a minimum of 16 core licenses required for each server. Core licenses are sold in packs of two, and you need to license all the physical cores on the server to run Hyper-V.
