    • Only the host is 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.
    • AVMA keys can be used only when the host is DataCenter edition

    The technical limit of VMs on any Hyper-V 2016 server is 1024 VMs.

    https://docs.microsoft.com/en-us/windows-server/virtualization/hyper-v/plan/plan-hyper-v-scalability-in-windows-server

    While you assign the license to the host, you do need to have the appropriate number of licenses for any Windows VMs, so you are licensing the VMs.

    Core licensing math aside, you need one Windows Server Standard license for every 2 Windows Server VMs meaning you must license all the cores again.  You may install the same Standard license on the host, and retain the 2 VM licenses as long as you're only running the Hyper-V role on the physical server.  Running another role will use one of these licenses and is generally regarded as not a best practice.

    A Windows Server Datacenter license allows for an unlimited number of Windows Server VMs on the physical host. 

    Neither Standard or Datacenter licensing offer any kind of licensing for Windows client OSes.  You would need special VDI licensing and Software Assurance to run client Windows VMs.

    There is no "Hyper-V license."  You license the particular OS the VM is running, i.e. a Windows Server License for a Windows Server VM, a RedHat license for a RH server, or as in CentOS, no license is needed for the VM.

    Sorry, but it does not work that way, but customers are advised that legal licensing questions are better directed towards your reseller's trained licensing specialist or ask microsoft directly. Any anonymous forums replies (including my own) are opinions at best and in no way legally binding.
