VFIO works with my other VMs.

I've set up macOS in Proxmox/qemu w/ gpu pass-through and 3d acceleration a few times. Most recently was a few months ago, but I stopped short of 3D acceleration.

Today, I wanted to start working on the 3D, after not using the VM for a couple of months, but after starting the vm, the screen was blank. I started to mess with my settings, and a few more stop/start cycles later I realized that I had a powered down secondary monitor connected to the GPU over displayport, which caused no signal to my main display. (I'm mentioning this on the off chance it could be relevant).

So I unplug the secondary monitor, revert my settings, and suddenly, when passing through my gpu, the vm hangs at the Apple logo w/ 0% on the progress bar. See the included image of verbose boot.

I can succesfully boot when using only the virtual console, so it's definitely a vfio problem, and more specifically a vfio+macos, since as I mentioned other vms work fine w/ gpu pass-through.

Initially I installed macos 12 with the Penryn cpu type (it might have been on Proxmox 7.X which has a 5.x kernel) but had to change it to haswell-noTSX to install ventura. Now, neither make a difference.

Incidentally, I'm now using proxmox 8.x (6.2.x kernel).

This is the guide i followed originally:

Here is a guide for Proxmox 8 and Ventura:

This is my vmid.conf:

As you can see, I'm messing with two different invocations of args. Depending on the CPU I select in args and in the "cpu:" serring, I either hang at the Apple logo, or crash/restart early on.

Thanks for reading, any help appreciated
