GPU passthrough

I’ve got 2 R9 Fury graphics cards, and I want to be able to pass the second card between KVM and the host without rebooting. I’m running Ubuntu 18.04 LTS, and a Ryzen 7 2700X.

I’ve also noticed an issue with loading the kvm_amd kernel module on 4.16+. It hangs on trying to load the ccp module, which is a driver for the PSP. The Canonical bundled kernel works fine with KVM however.
