macOS-KVM VS vfio

Does this guide solely focus on a bare metal install, or can I apply it to Hackintosh in virtual machines too? Used bare-metal for a few years but I’ve been trying to get a personalized kvm/OC config for my Monterey & Big Sur guests in proxmox 7. Both macOS versions boot and are decent but I do wish a host-setup like; https://github.com/johncolby/macOS-KVM. Instead of the more general approach; https://github.com/thenickdude/KVM-Opencore, https://github.com/Leoyzen/KVM-Opencore . Not to discredit either of them, I wouldn’t have a booting macOS without their guidance, but I’d like to tinker with it a bit further

You can look at this resource - https://github.com/johncolby/macOS-KVM. He links a couple of other guides- you should start with them first.

I went with a different case, AMD mini-ITX motherboard, and KVM VM rather than bare metal hackintosh, but if you want to check out my setup it is here: https://github.com/johncolby/macOS-KVM https://pcpartpicker.com/b/ZGn7YJ

i boot using opencore 0.6.5 with the config.plist from https://github.com/johncolby/macOS-KVM

https://github.com/johncolby/macOS-KVM/blob/feda3a501292df66c8d3930c312f0baaa3b3fa5f/EFI/OC/config.plist#L391

I was mainly following this guide to setup the VM and scripts: https://gitlab.com/Karuri/vfio

I've successfully set up single GPU passthrough as per https://gitlab.com/Karuri/vfio and https://github.com/joeknock90/Single-GPU-Passthrough .

- and a few other things mentioned here and here,

great thanks for the tip! havnt checked the logs for libvirt as i thought it was an osx issue. im using manjaro host, and have originally installed the vm using this https://github.com/foxlet/macOS-Simple-KVM, and this for the passthrough https://gitlab.com/Karuri/vfio

I used to have an RX580-based single GPU passthrough setup. You likely need the vendor reset module, since hot-plugging Polaris 10 GPUs is a bit buggy and can cause GPU lockups. It might also be worth dumping your GPU bios and configuring libvirt to use it so you get a visible boot screen (tool). I think I mostly followed this guide, however it hasn't been updated in quite a while it seems.

If you're up to the task you can follow this guide to get it working.

vfio-single-gpu-passthrough (this is for single gpu system, I link it for the section regarding hugepages, isolation, pinning & cpu governor which massively improved performance. It use script to dynamically run these only when you start a vm, so you can still use all of your cores when you stop the vm)
