A Project dedicated to making GPU Partitioning on Windows Hyper-V easier! Also known as GPU Paravirtualization (GPU-PV).
GPU-P allows you to partition your systems dedicated or integrated GPU and assign it to several Hyper-V VMs. It's the same technology that is used in WSL2, and Windows Sandbox.
Easy-GPU-P aims to make this easier by automating the steps required to get a GPU-P VM up and running.
Easy-GPU-P does the following...
- Creates a VM of your choosing
- Automatically Installs Windows 11 to the VM
- Partitions your GPU of choice and copies the required driver files to the VM
- Installs Parsec to the VM
WARNING: A work in progress...
- Wimndows 10 20H1+ Pro or Enterprise or Windows 11 Pro or Enterprise
- Desktop Computer with dedicated NVIDIA/AMD GPU or Integrated Intel GPU - Laptops with NVIDIA GPUs are not supported at this time, but Intel integrated GPUs work on laptops. GPU must support hardware video encoding (NVIDIA NVENC, Intel Quicksync or AMD AMF).
- Latest GPU driver from Intel.com or NVIDIA.com, don't rely on Device manager or Windows update.
- Latest Windows 10 ISO downloaded from here / Windows 11 ISO downloaded from here
- Virtualisation enabled in the motherboard and Hyper-V fully enabled on the Windows 11 OS (requires reboot)
- Allow Powershell scripts to run on your system - typically by running "Set-ExecutionPolicy unrestricted" in Powershell
- Make sure your system meets the prerequisits.
- Download the Repo and extract.
- Search your system for Powershell ISE and run as Administrator.
- In the extracted folder you downloaded, open PreChecks.ps1 in Powershell ISE.
- Open and Run PreChecks.ps1 in Powershell ISE using the green play button and copy the GPU Listed (or the warnings that you need to fix).
- Open CopyFilesToVM.ps1 and edit the params section at the top of the file, you need to be careful about how much ram, storage and hard drive you give it as you system needs to have that available. On Windows 10 the GPUName must be left as "AUTO", In Windows 11 it can be either "AUTO" or the specific name of the GPU you want to partition exactly how it appears in PreChecks.ps1. Additionally, you need to provide the path to the Windows 10/11 ISO file you downloaded.
- Run CopyFilesToVM.ps1 with your changes to the params section - this may take 5-10 minutes.
- View the VM in Hyper-V, once it gets to the Windows Desktop you will need to approve the certificate install request for Parsec and Virtual Audio Cable.
- Sign into Parsec on the VM.
- You should be good to go!
It's important to update the VM GPU Drivers after you have updated the Host GPUs drivers. You can do this by...
- Reboot the host after updating GPU Drivers.
- Open Powershell as administrator and change directory (CD) to the path that CopyFilestoVM.ps1 and Update-VMGPUPartitonDriver.ps1 are located.
- Run
Update-VMGPUPartitonDriver.ps1 -VMName "Name of your VM" -GPUName "Name of your GPU"
(Windows 10 GPU name must be "AUTO")
VMName = "GPUP"
- Name of VM in Hyper-V and the computername / hostname
SourcePath = "C:\Users\james\Downloads\Win11_English_x64.iso"
- path to Windows 11 ISO on your host
Edition = 6
- Leave as 6, this means Windows 11 Pro
VhdFormat = "VHDX"
- Leave this value alone
DiskLayout = "UEFI"
- Leave this value alone
SizeBytes = 40gb
- Disk size, in this case 40GB
MemoryAmount = 8GB
- Memory size, in this case 8GB
CPUCores = 4
- CPU Cores you want to give VM, in this case 4
UnattendPath = "$PSScriptRoot"+"\autounattend.xml"
-Leave this value alone
GPUName = "AUTO"
- AUTO selects the first available GPU. On Windows 11 you may also use the exact name of the GPU you want to share with the VM in multi GPU situations (GPU selection is not available in Windows 10 and must be set to AUTO)
GPUResourceAllocationPercentage = 50
- Percentage of the GPU you want to share with the VM
Team_ID = ""
- The Parsec for Teams ID if you are a Parsec for Teams Subscriber
Key = ""
- The Parsec for Teams Secret Key if you are a Parsec for Teams Subscriber
Username = "GPUVM"
- The VM Windows Username, do not include special characters
Password = "CoolestPassword!"
- The VM Windows Password
Autologon = "true"
- If you want the VM to automatically login to the Windows Desktop
Thanks to Hyper-ConvertImage for creating an updated version of Convert-WindowsImage that is compatible with Windows 10 and 11.
- Windows 10 20H1 is not well tested as I don't have any Win10 20H1 installs, if you have success on Windows 10 20H1 - 21H2 please let me know.
- A display or HDMI dummy dongle must be plugged into the GPU to allow Parsec to capture the screen.
- The screen may go black for times up to 10 seconds in sitautions when UAC prompts appear, applications go in and out of fullscreen and when you switch between video codecs in Parsec - not really sure why this happens, it's unique to GPU-P machines and seems to recover faster at 1280x720.
- Vulkan renderer is unavilable and GL games may or may not work.
