проброс видеокарты в qemu

я пытался пробросить видеокарту в qemu(8.0.3) запуская его через консоль вот такой скрипт у меня получился:

#!/bin/bash

#<===[default value]===>

DISC=1 # 0: test(install: kubuntu) | 1: windows(install)
NEW_SYS=0 # 0: no | 1: kubuntu | 2: windows
NEW_SYS_STR=""

#<===[stettings]===>

if [ -v 1 ]; then
    DISC=$1
fi

if [ -v 2 ]; then
    NEW_SYS=$2
fi

if (($DISC == 0)); then
    DISC_STR="virtual-disc-50G.img"
elif (($DISC == 1)); then
    DISC_STR="virtual-disc-50G-windows.img"
fi

if (($NEW_SYS == 1)); then
    NEW_SYS_STR="-boot d -cdrom $HOME/Downloads/kubuntu-22.04-desktop-amd64.iso"
elif (($NEW_SYS == 2)); then
    NEW_SYS_STR="-boot d -cdrom $HOME/Downloads/windows_22H2_or_21H2_x64/windows_22H2_or_21H2_x64.iso"
fi

#<===[start]===>

rm -rf ./qemu-output.txt

qemu-start () {
    qemu-system-x86_64 \
    -name andrewkoro105 \
    -machine accel=kvm \
    -enable-kvm \
    -cpu host \
    -smp 4 \
    -m 8G \
    -hda ${DISC_STR} \
    ${NEW_SYS_STR} \
    -device vfio-pci,host=04:00.0 \
    -device vfio-pci,host=04:00.1 \
    2> qemu-output.txt
}
qemu-start &

sleep 1

if [ ! -s ./qemu-output.txt ]; then
    xdotool key Super+b
    xdotool key Super+m
    xdotool key ctrl+alt+m
else
    echo "< ./qemu-output.txt >"
    cat ./qemu-output.txt
fi

при запуске у меня вылетает ошибка:

qemu-system-x86_64: -device vfio-pci,host=04:00.0: vfio 0000:04:00.0: group 0 is not viable
Please ensure all devices within the iommu_group are bound to their vfio bus driver.

Если что без проброса видеокарты всё работает отлично.

В ошибке сказано что нужно всем устройствам указать драйвер vfio но судя по выводу lspci -nnk далеко не у всем нужны драйвера, возможно это связано с тем сто видеокарта находится в iommu группе 0 в которой почему то много устройств (например моя основная видеокарта находится в группе 2 в которой всего 4 устройства).

На всякий случай держите список устройств в группе 0:

0000:00:01.0  0000:00:01.2  0000:02:00.0  0000:02:00.2  0000:03:04.0  0000:03:07.0  0000:03:09.0  0000:04:00.1  0000:09:00.0 0000:00:01.1  0000:01:00.0  0000:02:00.1  0000:03:00.0  0000:03:06.0  0000:03:08.0  0000:04:00.0  0000:05:00.0

и вывод команды lspci -nnk:

в которой почему то много устройств

https://wiki.archlinux.org/title/PCI_passthrough_via_OVMF#Bypassing_the_IOMMU_groups_(ACS_override_patch)

If you find your PCI devices grouped among others that you do not wish to pass through, you may be able to seperate them using Alex Williamson’s ACS override patch. Make sure you understand the potential risk of doing so.

You will need a kernel with the patch applied. The easiest method to acquiring this is through the linux-zen or linux-vfio package.

или ACS патч, или меняй местами 770 и 3060 и пускай иксы на 770
