AMD GPU Partitioning on Win 11 Hyper-V machine

Hi everyone!

I've created a virtual Win 11 Pro install with Hyper-V and want to dynamically share GPU resources with the VM

I followed this guide:
However, it refers to Nvidia GPUs and while i followed the instructions to the letter and copied over the files from system 32 starting with amd... and those starting with ati... and the largest folder from C:\Windows\System32\DriverStore\FileRepository, i can only see the integrated GPU in the VM: AMD Radeon Graphics and NOT the dedicated one, the beefy AMD Radeon RX 7900 XTX.

Can someone point me to the files that i need to copy over or the instructions that specifically speak about AMD GPUs partitioning?

Thanks!

This is more difficult than it sounds.

Tutorial: Passing through GPU to Hyper-V guest VM - Windows 10 Help Forums

I've learned so much about Hyper-V from all of the tutorials by @Kari and @Brink; that I hope I can return the favor here. I've created an account just to post this. My original problem: In the guest VM, my audio was out of sync when watching videos on yo

I came across that link but didnt help; will look again more closely.

I think the problem is that i have 2 GPUs, the integrated and the dedicated one. I can only see the Integrated one, i assume that the drivers of the dedicated one were not copied over, or another issue

Ok, I managed to fix the issue by pretty much deactivating the Integrated graphics card, which is not the best solution, BUT from what I read around it's not really possible to manually select the VMGpuPartitionAdapter, as it takes the first one available , which in my case is the integrated one.

What i have left to do is ensure that the right driver files are copied over to the WM: This took me a lot of googling to figure out, but I think the best way to do it is to open Device Manager ->Select the GPU, Properties -> Driver Details and copy over the dozens of files that are mentioned there

Left is the VM and right is the Host.

Please note the VM Driver date is 2006 and the Host date is 2023. Not sure of the implications of this, Probably have to ensure that the driver files are in C:\Windows\System32\HostDriverStore\FileRepository\ and not in C:\Windows\System32\

I guess it's fine. It gets a different hardware Id as well.
I've encountered this a while back, posted here on TenForums.

The partitioned GPU will get a different hardware id, logically as this isn't the entire GPU only 'a part' of it so it's a different device but with access to host capable graphics.
