    I've gotten a thrust into the gpu in a server world about a month ago and i'm finding it hard to believe that MS best answer to vmware and citrix is DDA.  What is in the works?  I can see how dda is a step forward from remote fx allowing the os to have direct access to the hardware, However there should still be a way to have a layer between that allows the hardware to be utilized on what ever vm needs it.  Is there an update to hyper-v on the way?

    many thanks,

    matt

    Hi Matt,

    I want to say that your current discovery is correct, Microsoft on how to do this is just using DDA. which works from Hyper-V Server 2016+.

    https://docs.microsoft.com/en-us/windows-server/virtualization/hyper-v/deploy/deploying-graphics-devices-using-dda

    Let me explain something, smart as you maybe have known all of them:

    1.GPU acceleration is based on RemoteFX, which is part of the Remote Desktop Service.

    2.We need to be aware of is the fact that not every Hyper-V virtual machine can take advantage of GPU acceleration. Obviously, guest operating system support is required, but there is more to it than that. When you create a virtual machine in Hyper-V, you are asked whether you would like to create a Generation 1 virtual machine or a Generation 2 virtual machine. Generation 2 virtual machines do not include an option to add a RemoteFX 3D Video Adapter. The option exists only for Generation 1 virtual machines.

    3.The config UI of RemoteFX vGPU has been removed from Hyper-V Manager of Windows Server 2019, you can configure RemoteFX vGPU by using Powershell on Windows Server 2019.
