OSX-KVM
Run macOS on QEMU/KVM. With OpenCore + Monterey + Ventura + Sonoma support now! Only commercial (paid) support is available now to avoid spammy issues. No Mac system is required.
I followed the OSX KVM guide from kholia. When I enable IOMMU support and configure VFIO in /etc/default/grub and etc/modprobe.d/vfio.conf respectively, my screen is off as soon as I boot into Ubuntu (isn't it supposed to do that only when I run the VM in QEMU?).

Also, I tried following this guide instead OSX_GVT-D and created a boot.sh file with content as shown below: IGPU_PCIID="8086 1916" modprobe vfio_pci modprobe vfio echo 0000:00:02.0 > /sys/bus/pci/devices/0000:00:02.0/driver/unbind echo $IGPU_PCIID > /sys/bus/pci/drivers/vfio-pci/remove_id echo $IGPU_PCIID > /sys/bus/pci/drivers/vfio-pci/new_id modprobe -r i915 sleep 2 ./OpenCore-Boot.sh sleep 2 modprobe -r vfio_pci modprobe -r vfio modprobe i915

I followed the steps shown in this [video][https://youtu.be/_JTEsQufSx4] and read the [RisingPrism guide[https://gitlab.com/risingprismtv/single-gpu-passthrough/-/wikis/home] thoroughly. Had more luck than before, however I'm experiencing a black screen, just like @KENDEN described.

Could it be the GPU VBIOS rom? I got it from [this][https://github.com/patmagauran/i915ovmfPkg] GitHub repo. Also tried dumping the rom, but I imagine it's not so straightforward when it comes to an integrapted graphics card.
