Virtualisation and passthrough issues

[sappheon]

Hey guys,

Let me preface this by saying I'm not sure if this post belongs here, but I've seen other virtualisation related posts in here so I figured this was my best bet.

I've been trying to set up a virtualised windows environment with my 1080ti passed through. I was able to install windows successfully on my nvme drive.

Now my issue is that when I boot up the vm, windows just seems to be completely oblivious to the existence of the graphics card.

I've installed the nvidia drivers (by booting to the drive directly, otherwise even the nvidia drivers didn't pick up the card), and still nothing in the virtual environment.

I feel like I've tried everything. I've triple checked that the graphics card is in its own IOMMU group (and it is), I've checked that the correct driver is being used (and it is; `lspci -nnv` says it's vfio-pci).

What can I possibly be missing? I've looked at at least 4 different guides/tutorials, and none of them have a step that I could have missed.

Thanks

What are you running the VM in?  Might be a stupid question.  “Virtualized windows environment” might be specific.  Sounds like a VM though.  There are lots of OSes that will run VMs.

Oh right, the host OS is linux. Sorry, forgot to mention ^^
