我跟着这个帖子设置直通。我还参考了一些其他文章。我按照以下方法安装了驱动程序本文。
对于 qemu 2.2，我尝试了以下两个选项：
-device ioh3420,bus=pcie.0,addr=1c.0,multifunction=on,port=1,chassis=1,id=root.1 \
-device vfio-pci,host=02:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on \
-device vfio-pci,host=02:00.1,bus=root.1,addr=00.1 \
-M q35
和
-device vfio-pci,host=02:00.0,multifunction=on,x-vga=on \
-device vfio-pci,host=02:00.1 \
-vga none
当我lspci -vv在客人上运行：

当我运行 smi 时：
$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

我尝试了好几天都没找到答案，重新绑定了 GPU，重新安装了驱动程序等等。但我仍然不知道哪一步出了问题。
我是否成功通过了 GPU？如何才能让它在客户机上运行？
任何帮助都将非常有帮助。提前致谢。
