PVE8 直通 ubuntu 22.04
p102显卡在PVE8下直通给 ubuntu 22.04 虚拟机的设置
准备工作
在 pve8 下查看两块 p102 显卡的信息：
lspci | grep 3D
81:00.0 3D controller: NVIDIA Corporation GP102 [P102-100] (rev a1)
83:00.0 3D controller: NVIDIA Corporation GP102 [P102-100] (rev a1)
要直通这两块卡给 ubuntu 22.04 虚拟机，需要准备：
- 开启 pcie 直通
- 安装 ubuntu 22.04 虚拟机
修改 device ID
直通显卡时，需要修改显卡的设备ID，仿冒 1080 TI 显卡。
- Vendor ID: 0x10DE
- Device ID: 0x1B06
- Sub-Vendor ID: 0x0000
- Sub-Device ID: 0x0000
直通给 ubuntu 22.04
之后将两块卡都直通给 ubuntu 22.04 虚拟机：
启动 ubuntu 22.04 之后，查看显卡信息：
lspci | grep 3D
01:00.0 3D controller: NVIDIA Corporation GP102 [GeForce GTX 1080 Ti] (rev a1)
02:00.0 3D controller: NVIDIA Corporation GP102 [GeForce GTX 1080 Ti] (rev a1)
安装 nvidia 驱动
参考：How to install the NVIDIA drivers on Ubuntu 22.04
更新系统
安装驱动前先更新一下
sudo apt update
sudo apt upgrade
sudo reboot
重启之后，如果有内核更新，可以先删除不用的旧内核。
检测显卡和推荐驱动
执行下面的命令
sudo ubuntu-drivers devices
输出为：
$ sudo ubuntu-drivers devices
ERROR:root:aplay command not found
== /sys/devices/pci0000:00/0000:00:1c.1/0000:02:00.0 ==

可以看到推荐的是 nvidia-driver-535 驱动。
如果同意推荐的驱动，则直接安装：
sudo ubuntu-drivers autoinstall
输出为:
