Hyper-V GPU passthrough

GPU Partitioning

GPU partitioning is a method to partition off resources from your graphics card so that it can be used inside your VMs. Hyper-V supports is GPU passthrough, a feature that allows virtual machines to access the host’s GPU directly. this feature allows graphics intensive workloads like gaming or video editing on Hyper-V guest.

This posting explains how to set GPU to Hyper-V window VM

Window Powershell commands

Test to see if your GPU can be partitioned at all. On the Host, open a Powershell prompt as administrator.

Get-VMPartitionableGpu (win10)

or

Get-VMHostPartitionableGpu (win11)

Requirements

• Need a GPU that supports GPU virtualization, such as NVIDIA GRID or AMD MxGPU technology
• Your CPU needs to support IOMMU (Input-Output Memory Management Unit) virtualization, which is required for GPU passthrough
• GPU passthrough is not supported for virtual machines that use Dynamic Memory
• GPU passthrough is only available on specific editions of Windows Server, such as the Datacenter edition
