I'm assuming you are using an AMD GPU? The last time I looked, there were significant challenges with getting a Nvidia or iGPU to work.

- xienze 10y agoYes, AMD. I would prefer Nvidia, but it is what it is.
- mastax 10y agoThe issues I know of with GPU passthrough are: Non-Quadro NVIDIA cards don't want to work in a VM so you need to disguise KVM to get them to work. NVIDIA says this is a bug but I think they just want you to buy quadro cards. [1] AMD Bonaire and Hawaii architecture cards have issues with resetting in a VM, so you can't let the VM go to sleep or shutdown. Newer (R9 480) or older AMD cards don't have this issue.

- xienze 10y agoDo you have a source that confirms that the 480 doesn't have this issue? I currently have a set of scripts that disable/enable my 380X automatically when my VM stops/starts and I would love to get rid of them (and get a new card as well).
