GPU disabled after enabling Hyper-V

Question

After changing the CMOS battery, I noticed that every time I turn on Hyper-V, my GPU gets disabled. When I turn off Hyper-V, the GPU works again. Does anyone know why this is happening and how to fix it?

Hi Mahmoud Attiyah,

Thanks for your post. Can I know if you have configure the utilize GPU capabilities within Hyper-V virtualization, you have a few alternative options:

1. RemoteFX: Hyper-V provides RemoteFX, which allows you to use the GPU on the host machine to accelerate graphics-intensive workloads in virtual machines. However, please note that RemoteFX has been deprecated by Microsoft, starting with Windows Server 2019. It is still available in older versions, but it's not recommended for new deployments.
2. GPU passthrough: If you have a specific use case that requires direct access to the physical GPU, you might consider using other virtualization platforms like VMware ESXi or Citrix XenServer, which offer GPU passthrough functionality. This feature allows you to assign a physical GPU directly to a virtual machine, providing near-native performance. However, this approach may have hardware and software compatibility requirements.
3. Cloud-based GPU instances: If your primary objective is to leverage GPU resources for tasks like machine learning or graphical rendering, you can consider using cloud providers that offer GPU instances, such as Amazon EC2, Microsoft Azure, or Google Cloud Platform. These services provide virtual machines with dedicated GPU resources and specialized GPU-accelerated instances.

Apart from this, You need a GPU that supports GPU virtualization, such as an NVIDIA or AMD GPU that supports NVIDIA GRID or AMD MxGPU technology. Your CPU needs to support IOMMU (Input-Output Memory Management Unit) virtualization.

It's important to evaluate your specific requirements and constraints before deciding on the best approach for utilizing GPU resources within a virtual machine.
