GPU Partitioning on windows laptop for VMs w/ Windows Hyper-V

A compilation of information on how to do GPU Paravirtualization on windows laptop using Windows Hyper-V.

Based on Craft Computing tutorial video https://www.youtube.com/watch?v=XLLcc29EZ_8&t=707s&ab_channel=CraftComputing with some adaptations from different sources . Follow the video and pay attention to the differences described bellow on step 7. and 8.

Requirements

Windows 10 Pro or Windows 11 Pro/ Enterprise (Required for HyperV) Updated GPU Drivers

1. Installation Instructions

Install HyperV (Turn Windows Features On or Off)

- Configure virtual switch for External Network
- Disable Enhanced Sessions

2. Verify GPU Compatibility

- Check with Powershell: Get-VMPartitionableGPU

3. Create New VM:

- Gen 2
- 4GB Ram 
- 120GB HDD (or how much you want to alocate)

4. VM Settings:

- 8 CPU Cores 
- Disable Checkpoints

5. Start VM + Install Windows using ISO file

6. Driver Installation

File Transfers

- HOST - C:\Windows\System32\DriverStore\FileRepository\nv_dispi.inf_amd64_[UUID]
- GUEST - - To C:\Windows\System32\HostDriverStore\FileRepository\nv_dispi.inf_amd64_[UUID] (You will have to create C:\Windows\System32\HostDriverStore\FileRepository)

- HOST - C:\Windows\System32\nv*.* (Every file that begins with nv)
- GUEST - C:\Windows\System32\

NOTE on Laptop - The name of the drivers will be different, Device Manager > Your Graphics Card > Properties > Driver > Driver Details > Scroll all the way down, that's the folder you need.

• GPU Partition -

7. Run PowerShell ISE as Administrator

Open GPU-P-Partition.ps1

- Set $vm = [VM-NAME]
- Set-ExecutionPolicy Unrestricted
- Set $instance_name = [Instance_name] (Only for Laptop)
- Run Script with Play button

NOTE on Laptop - Use "Get-VMHostPartitionableGPU" in powershell to get the details of Partitionable GPU in your laptop

Then cross-check the "Name" of the GPU via Device Manager>DisplayAdapter>GPU>Properties>Events with that of Names that came as Output in Powershell

Take the said name from the Output in Powershell and substitute on the GPU-P-Partition.ps1 script in this repository on $instance_name = "said name"

This will allocated your desired GPU to VM in Hyper-V

8. Start VM

Check to see if driver is loaded on VM device manager

PostInstall Steps (Original Intended for gaming, no need otherwise)

Install Parsec from Parsec.app Install VBCable Audio Device Emulator Install USB Monitor Virtual Driver Install Riva Tuner from: https://www.guru3d.com/files-details/rtss-rivatuner-statistics-server-download.html - Recommend limiting VM to 60 FPS - Adjust frame limits for Host and VM. Don't forget to tweak game settings.

Connect to the VM via Parsec and GAME ON!
