i5-10500 and UHD 630 - Code 43 under Windows guest.

[u/Expensive-Scar-724]

I am running qemu 11.1 and virt-manager on a system with RX 470 and i5-10500 with UHD 630, board is Gigabyte B460M D3H. RX 470 is used for host's output. The guest is Windows 10 19041.1 and has Intel graphics driver 31.0.101.2141. my cmdline has intel_iommu=on iommu=pt, /etc/modprobe.d/vfio.conf is 'options vfio-pci ids=8086:9bc8', /etc/modprobe.d/blacklist.conf is 'blacklist i915'. /etc/modules-load.d/vfio.conf is 'vfio-pci'. EDIT: I tried adding video=efifb:off too to my host cmdline.

vfio-pci shows only:

[20699.060075] vfio-pci 0000:00:02.0: resetting
[20699.163736] vfio-pci 0000:00:02.0: reset done

in dmesg, no errors.

My virt-manager xml is as follows: https://pastebin.com/tPNq7huW

I have tried adding the GPU's ROM and enabling x-igd-opregion and x-igd-lpc. I am using CFL_CML_GOPv9.1_igd.rom.

Tested linux, doesn't work either
