我正在使用 Ubuntu 21.04。我有一台 AMD Radeon RX550 和一台 Nvidia GTX 1050Ti
我正在尝试在 Windows VM 中为 nvidia 卡设置 VFIO 直通。在虚拟机上安装 nvidia 驱动程序后，Windows 在设备管理器中报告 nvidia 卡上的错误代码 43，并且我在 VM 中卡在 800x600。
主卡是 AMD（即打开物理机时显示 BIOS 帖子的卡）我已删除 nvidia 驱动程序，将 nvidia 和 nouveau 列入黑名单 /etc/modprobe.d/nvidea-graphics-drivers.conf
blacklist nvidia
blacklist nouveau
在 grub 中我将 VFIO-PCI 连接到 nvidea 卡，如下所示
GRUB_CMDLINE_LINUX_DEFAULT="intel_iommu=on kvm.ignore_msrs=1 vfio-pci.ids=10de:1c82,10de:0fb9 vfio_iommu_type1.allow_unsafe_interrupts=1 video=vesafb:off video=efifb:off"
我已尝试按照这些说明解决代码 43 https://mathiashueber.com/fighting-error-43-nvidia-gpu-virtual-machine/

如您所见，每个设备都有自己的 IOMMU 组（这是一个服务器主板）。
dmesg 中没有来自 VFIO 的错误。我不知道如何解决这个问题，任何帮助都将不胜感激。
