还没有配置显卡直通（passthrough），当前状态如下：

项目 状态 说明
GRUB_CMDLINE_LINUX_DEFAULT quiet ❌ 没启用 intel_iommu=on iommu=pt
/etc/modules 空 ❌ 没加载 vfio 模块
vfio.conf / blacklist.conf 不存在 ❌ 没绑定或屏蔽驱动
显卡驱动 nouveau ❌ 已被宿主机驱动占用，不能直通

2. 配置显卡直通

依次执行以下命令：

1. 修改 GRUB 配置启用 IOMMU

sed -i 's/GRUB_CMDLINE_LINUX_DEFAULT="quiet"/GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt"/' /etc/default/grub
update-grub

2. 添加内核模块（VFIO）

cat <<EOF > /etc/modules
vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd
EOF

3. 使用 vfio 绑定 NVIDIA 显卡（03:00.0 和 03:00.1）

根据第一步命令得到自己的信息

cat <<EOF > /etc/modprobe.d/vfio.conf
options vfio-pci ids=10de:13ba,10de:0fbc
EOF

我这块显卡的设备 ID 是：

  • 显卡：10de:13ba
  • 音频：10de:0fbc

4. 禁用宿主驱动（nouveau）

echo "blacklist nouveau" > /etc/modprobe.d/blacklist.conf
echo "options nouveau modeset=0" >> /etc/modprobe.d/blacklist.conf
update-initramfs -u

5. 修改 VM 配置（添加pci 原始设备）

file
启用所有功能
file

✅ 最后：重启宿主机

reboot

🔍 验证是否成功 passthrough

  1. 宿主机重启后，运行以下命令确认驱动被 vfio-pci 接管：
lspci -nnk | grep -A 15 -i nvidia

你应看到：

Kernel driver in use: vfio-pci
root@pve:~# lspci -nnk | grep -A 15 -i nvidia
03:00.0 VGA compatible controller [0300]: NVIDIA Corporation GM107GL [Quadro K2200] [10de:13ba] (rev a2)
        Subsystem: NVIDIA Corporation GM107GL [Quadro K2200] [10de:1097]
        Kernel driver in use: vfio-pci
        Kernel modules: nvidiafb, nouveau

        Kernel driver in use: vfio-pci
        Kernel modules: snd_hda_intel

3. FNos影视提示GPU1未启用

原因

root\@:/vol1/@appcenter/docker-xunlei/app#  lspci -nnk | grep -A 15 -i nvidia

当前加载的是 nouveau（开源驱动），不是 NVIDIA 官方驱动

解决

1. 安装 NVIDIA 官方驱动

sudo apt update
sudo apt install nvidia-driver -y

2. 禁用 nouveau 驱动（官方驱动要求）

创建文件：

sudo nano /etc/modprobe.d/blacklist-nouveau.conf

添加内容：

blacklist nouveau
options nouveau modeset=0

更新 initramfs：

sudo update-initramfs -u

然后重启：

sudo reboot

3. 安装 NVIDIA 驱动后验证

重启后执行：

如果能看到驱动版本和 GPU 信息，说明安装成功。
