|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
## 设备配置

|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
## Proxmox VM host 环境配置
|
||||||
|
|
||||||
|
### 配置软件源
|
||||||
|
|
||||||
|
1. 删除企业源和 Ceph 源
|
||||||
|
|
||||||
|
```bash
|
||||||
|
rm /etc/apt/sources.list.d/pve-enterprise.list
|
||||||
|
rm /etc/apt/sources.list.d/ceph.list
|
||||||
|
```
|
||||||
|
|
||||||
|
2. 修改软件源为国内源
|
||||||
|
|
||||||
|
```bash
|
||||||
|
nano /etc/apt/sources.list
|
||||||
|
# 内容修改为如下内容
|
||||||
|
deb https://mirrors.aliyun.com/debian/ bookworm main contrib non-free
|
||||||
|
deb-src https://mirrors.aliyun.com/debian/ bookworm main contrib non-free
|
||||||
|
deb https://mirrors.aliyun.com/debian/ bookworm-updates main contrib non-free
|
||||||
|

|
||||||
|
deb-src https://mirrors.ustc.edu.cn/debian-security/ stable-security main contrib non-free
|
||||||
|
```
|
||||||
|
|
||||||
|
### 其他系统配置
|
||||||
|
|
||||||
|
1. 开启 iommu
|
||||||
|
|
||||||
|
```bash
|
||||||
|
nano /etc/default/grub
|
||||||
|
# 找到
|
||||||
|
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
|
||||||
|
# 改为：
|
||||||
|
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt"
|
||||||
|
# 更新 grub
|
||||||
|
update-grub
|
||||||
|
```
|
||||||
|
|
||||||
|
2. 加载 vfio 模块
|
||||||
|
|
||||||
|
```bash
|
||||||
|
echo vfio >> /etc/modules
|
||||||
|
echo vfio_iommu_type1 >> /etc/modules
|
||||||
|
echo vfio_pci >> /etc/modules
|
||||||
|
echo vfio_virqfd >> /etc/modules
|
||||||
|
```
|
||||||
|
|
||||||
|
3. 屏蔽现有开源驱动，然后重启
|
||||||
|
|
||||||
|
```bash
|
||||||
|
echo "blacklist nouveau" >> /etc/modprobe.d/blacklist.conf
|
||||||
|
echo "blacklist nvidia" >> /etc/modprobe.d/blacklist.conf
|
||||||
|
echo "blacklist nvidiafb" >> /etc/modprobe.d/blacklist.conf
|
||||||
|
# 更新内核参数
|
||||||
|
update-initramfs -k all -u
|
||||||
|
```
|
||||||
|
|
||||||
|
### 修改显卡模式
|
||||||
|
|
||||||
|
1. 如果 GPU 带显示接口，需要修改显卡模式。使用下面的命令检查，如果结果中显示为 VGA compatible controller 就需要修改。
|
||||||
|
|
||||||
|
```bash
|
||||||
|
lspci | grep NVIDIA
|
||||||
|
# 执行结果
|
||||||
|
17:00.0 VGA compatible controller: NVIDIA Corporation GA102GL [RTX A6000] (rev a1)
|
||||||
|
17:00.1 Audio device: NVIDIA Corporation GA102 High Definition Audio Controller (rev a1)
|
||||||
|
65:00.0 VGA compatible controller: NVIDIA Corporation GA102GL [RTX A6000] (rev a1)
|
||||||
|
65:00.1 Audio device: NVIDIA Corporation GA102 High Definition Audio Controller (rev a1)
|
||||||
|
ca:00.0 VGA compatible controller: NVIDIA Corporation GA102GL [RTX A6000] (rev a1)
|
||||||
|
ca:00.1 Audio device: NVIDIA Corporation GA102 High Definition Audio Controller (rev a1)
|
||||||
|
e3:00.0 VGA compatible controller: NVIDIA Corporation GA102GL [RTX A6000] (rev a1)
|
||||||
|
e3:00.1 Audio device: NVIDIA Corporation GA102 High Definition Audio Controller (rev a1)
|
||||||
|
```
|
||||||
|
|
||||||
|
2. 下载 NVIDIA Display Mode Selector Utility，可以从[这里](https://index.mitsea.com/%E8%BD%AF%E4%BB%B6/%E5%BA%94%E7%94%A8%E7%A8%8B%E5%BA%8F/Display_Mode-1.61.0.zip)下但是不保证链接有效性
|
||||||
|
3. 检查当前显卡，获得序号
|
||||||
|
|
||||||
|
```bash
|
||||||
|
chmod +x displaymodeselector
|
||||||
|
./displaymodeselector --list
|
||||||
|
```
|
||||||
|
|
||||||
|
4. 修改显卡模式
|
||||||
|
|
||||||
|
```bash
|
||||||
|
./displaymodeselector --gpumode physical_display_disabled -i 0
|
||||||
|
./displaymodeselector --gpumode physical_display_disabled -i 1
|
||||||
|
./displaymodeselector --gpumode physical_display_disabled -i 2
|
||||||
|
./displaymodeselector --gpumode physical_display_disabled -i 3
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
5. 重启服务器，重启后应该显示为 3D Controller
|
||||||
|
|
||||||
|
```bash
|
||||||
|
17:00.0 3D controller: NVIDIA Corporation GA102GL [RTX A6000] (rev a1)
|
||||||
|
65:00.0 3D controller: NVIDIA Corporation GA102GL [RTX A6000] (rev a1)
|
||||||
|
ca:00.0 3D controller: NVIDIA Corporation GA102GL [RTX A6000] (rev a1)
|
||||||
|
e3:00.0 3D controller: NVIDIA Corporation GA102GL [RTX A6000] (rev a1)
|
||||||
|
```
|
||||||
|
|
||||||
|
### 安装驱动
|
||||||
|
|
||||||
|
1. 安装 NVIDIA Driver 安装时需要的依赖
|
||||||
|
|
||||||
|
```bash
|
||||||
|
apt update
|
||||||
|
apt install build-essential dkms mdevctl pve-headers-$(uname -r)
|
||||||
|
```
|
||||||
|
|
||||||
|
2. 安装驱动，下载的驱动包有好几个驱动，安装 host 驱动。驱动可以从[这里](https://index.mitsea.com/%E8%BD%AF%E4%BB%B6/%E9%A9%B1%E5%8A%A8%E5%92%8C%E5%85%B6%E4%BB%96%E9%95%9C%E5%83%8F/NVIDIA-GRID-Linux-KVM-535.104.06-535.104.05-537.13.zip)下，但是不保证链接有效性。把驱动传到服务器上后，设置执行权限后运行。
|
||||||
|
|
||||||
|
```bash
|
||||||
|
chmod +x NVIDIA-Linux-x86_64-535.104.06-vgpu-kvm.run
|
||||||
|
./NVIDIA-Linux-x86_64-535.104.06-vgpu-kvm.run --dkms
|
||||||
|
```
|
||||||
|
|
||||||
|
3. 执行 `nvidia-smi` 后无误即可

## 搭建 vGPU 授权服务器
|
||||||
|
|
||||||
|
[Oscar Krause / FastAPI-DLS · GitLab](https://git.collinwebdesigns.de/oscar.krause/fastapi-dls)
|
||||||
|
|
||||||
|
按照仓库 Readme 搭建就行了，主要就是强制 https，本地的话需要生成一个自签名证书。法外狂徒挂公网可以无视，nginx 证书配好就行。对于挂在公网上有几个注意点：
|
||||||
|
|
||||||
|
1. docker 命令中的 `DLS_URL=`hostname -i`` 填你反代时要使用的域名例如`DLS_URL=`xxx.xxx.com``
|
||||||
|
2. `DLS_PORT=443` 不要动，只改 port 映射出去的端口，比如改成 `-p 4433:443` 这样反代那边就反代容器 IP:4433
|
||||||
|
|
||||||
|
## 虚拟机添加设备
|
||||||
|
|
||||||
|
开机后需要启用 SR-IOV 设备，每次开机都要执行，可以写成一个服务开机自动执行一次
|
||||||
|
|
||||||
|
```jsx
|
||||||
|
/usr/lib/nvidia/sriov-manage -e ALL
|
||||||
|
```
|
||||||
|
|
||||||
|
Raw Device 选择一个不是 .0 的设备后，MDev Type 就可以选 vGPU Profile 了。如果想要用整张显卡，也不要通 .0 的设备，据说会容易导致 pve 爆炸失联，建议还是选择一个用完所有显存的 Profile。
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||

## 激活 vGPU 授权
|
||||||
|
|
||||||
|
参考激活服务器 Readme 中 Setup Client 一节
|
||||||
|
|
||||||
|

|
||||||
|
### Windows
|
||||||
|
|
||||||
|
1. 进入 Windows 后先安装之前那个驱动包里的 host 驱动
|
||||||
|
2. 从 https://<你的dls服务器>/-/client-token 上下载配置文件，然后放到 C:\Program Files\NVIDIA Corporation\vGPU Licensing\ClientConfigToken 下
|
||||||
|
3. 重启电脑，然后就能看到正在获取许可证并激活成功
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
### Linux
|
||||||
|
|
||||||
|
执行下面的命令
|
||||||
|
|
||||||
|
```bash
|
||||||
|
curl --insecure -L -X GET https://<dls-hostname-or-ip>/-/client-token -o /etc/nvidia/ClientConfigToken/client_configuration_token_$(date '+%d-%m-%Y-%H-%M-%S').tok
|
||||||
|
service nvidia-gridd restart
|
||||||
|
```
