Passagem de GPU KVM NVIDIA 660TI usando Seabios

Passagem de GPU KVM NVIDIA 660TI usando Seabios

Estou usando o Debian 10 (teste) com kernel 4.19.0-5_amd. Eu uso KVM e quero passar para minha VM a placa gráfica NVIDIA GTX 660Ti que não suporta UEFI. Eu li muitos tutoriais sobre como passar a GPU secundária em uma máquina virtual, mas as coisas são realmente confusas porque a maioria usa uma placa gráfica que suporta UEFI.

Eu segui todas as etapas deste tutorial (https://heiko-sieger.info/running-windows-10-on-linux-using-kvm-with-vga-passthrough/) e abaixo tenho os resultados:

No /etc/default/grubarquivo, tenho esta linha:

GRUB_CMDLINE_LINUX_DEFAULT="quiet nomodeset intel_iommu=on i915.enable_hd_vgaarb=1"

Meu arquivo xml da VM é:

Quando inicio a VM com o comando

virsh start WIN-DEV-SRV

ocorreu o erro abaixo

error: Failed to start domain WIN-DEV-SRV
error: internal error: qemu unexpectedly closed the monitor: 2019-06-02T17:23:59.871333Z qemu-system-x86_64: -device vfio-pci,host=03:00.0,id=hostdev0,bus=pci.4,multifunction=on,addr=0x0: vfio 0000:03:00.0: failed getting region info for VGA region index 8: Invalid argument
