저는 Debian 10(테스트)과 커널 4.19.0-5_amd를 사용하고 있습니다. KVM을 사용하고 UEFI를 지원하지 않는 NVIDIA GTX 660Ti 그래픽 카드를 내 가상 머신에 전달하고 싶습니다. 가상 머신에서 보조 GPU를 전달하는 방법에 대한 많은 튜토리얼을 읽었지만 대부분 UEFI 지원 그래픽 카드를 사용하기 때문에 이러한 튜토리얼은 정말 혼란스럽습니다.
나는 이 튜토리얼의 모든 단계를 따랐습니다(https://heiko-sieger.info/running-windows-10-on-linux-using-kvm-with-vga-passthrough/) 결과 아래에는 다음과 같은 결과가 표시됩니다.
코드 03:00.0으로 장치를 전달하고 싶습니다.
내 장치에는 다른 장치가 포함되어 있지 않으므로 내 IOMMU 그룹이 정확합니다!
/etc/default/grub파일 에는 다음 줄이 있습니다.
GRUB_CMDLINE_LINUX_DEFAULT="quiet nomodeset intel_iommu=on i915.enable_hd_vgaarb=1"
내 가상 머신 XML 파일은 다음과 같습니다
