Hello!

I am trying to passthrough the single iGPU in this Intel NUC, but it always gives error code 43 in my Windows 8 VM.
The config file is as the following:
agent: 1 bios: ovmf boot: order=scsi0;ide2;net0 cores: 2 cpu: host efidisk0: local-lvm:vm-101-disk-0,efitype=4m,pre-enrolled-keys=1,size=4M hostpci0: 0000:00:02,pcie=1,romfile=iGPU.rom ide2: local:iso/virtio-win-0.1.229.iso,media=cdrom,size=522284K machine: pc-q35-6.2 memory: 2048 meta: creation-qemu=8.0.2,ctime=1698173603 name: Windows-8 net0: virtio=C6:10:38:7B:40:25,bridge=vmbr0,firewall=1 numa: 0 ostype: win8 scsi0: local-lvm:vm-101-disk-1,iothread=1,size=50G scsihw: virtio-scsi-single smbios1: uuid=2bf9fed8-d396-44f1-9a64-12a578531728 sockets: 1 tpmstate0: local-lvm:vm-101-disk-2,size=4M,version=v2.0 vga: none vmgenid: b3964b71-4c4d-4baa-80f1-4e66bb10ef73
My kernel parameters:
BOOT_IMAGE=/boot/vmlinuz-6.2.16-15-pve root=/dev/mapper/pve-root ro quiet intel_iommu=on iommu=pt pcie_acs_override=downstream,multifunction initcall_blacklist=sysfb_init video=simplefb:off video=vesafb:off video=efifb:off video=vesa:off disable_vga=1 vfio_iommu_type1.allow_unsafe_interrupts=1 kvm.ignore_msrs=1 modprobe.blacklist=radeon,nouveau,nvidia,nvidiafb,nvidia-gpu,snd_hda_intel,snd_hda_codec_hdmi,i915
I also did all other steps like blacklisting the iGPU from loading in the modprobe.d folder, and let it load all VFIO modules. IOMMU is enabled. My GPU is an Intel(R) HD Graphics 620 as I said.
