How to single GPU passthrough VM

I use Oracle Virtualbox right now, but you can give me instructions to a vm software of your liking.
Like i stated in the title, i want to know how to passthrough my GPU to a VM (i only have one)
If you like, you can also point me to another forum where i can ask this question.

Have you read through this?

Also, just a fair warning that single GPU passthrough is not a simple or particularly user-friendly process.

It's like a Christmas Gift :wink:

No, does not work for me. I tried that and all i got at the end is a blackscreen. And yes, i did everything like it said in that guide. At least i think i did. I checked 3 times.

Like I said, it isn't plug and play. Expect to have to do some troubleshooting and research.
