在Proxmox VE 7.2 中开启vGPU_unlock，实现显卡虚拟化

一：参考7.1安装vGPU_unlock

二： 配置软件源

1. rm /etc/apt/sources.list
2. rm /etc/apt/sources.list.d/*
3. echo “deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye main contrib non-free”>>/etc/apt/sources.list
4. echo “deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye-updates main contrib non-free”>>/etc/apt/sources.list
5. echo “deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye-backports main contrib non-free”>>/etc/apt/sources.list
6. echo “deb https://mirrors.tuna.tsinghua.edu.cn/debian-security bullseye-security main contrib non-free”>>/etc/apt/sources.list
7. echo “deb https://mirrors.tuna.tsinghua.edu.cn/proxmox/debian bullseye pve-no-subscription”>>/etc/apt/sources.list

三：安装软件包

1. apt update && apt install dkms git build-essential pve-kernel-5.15 pve-headers-5.15 dkms cargo jq uuid-runtime -y

安装mdevctl

1. wget -P /opt/ http://ftp.br.debian.org/debian/pool/main/m/mdevctl/mdevctl_0.81-1_all.deb
2. dpkg -i /opt/mdevctl_0.81-1_all.deb

四：配置内核

1. echo vfio >> /etc/modules
2. echo vfio_iommu_type1 >> /etc/modules
3. echo vfio_pci >> /etc/modules
4. echo vfio_virqfd >> /etc/modules
5. echo “blacklist nouveau” >> /etc/modprobe.d/blacklist.conf
6. echo “options kvm ignore_msrs=1” > /etc/modprobe.d/kvm.conf
7. update-initramfs -k all -u

五：配置引导

1. #编辑grub，请不要盲目改。根据自己的环境，选择设置
2. nano /etc/default/grub
3. #在里面找到：
4. GRUB_CMDLINE_LINUX_DEFAULT=”quiet”
5. #然后修改为：
6. GRUB_CMDLINE_LINUX_DEFAULT=”quiet intel_iommu=on iommu=pt”
7. #如果是amd cpu请改为：
8. GRUB_CMDLINE_LINUX_DEFAULT=”quiet amd_iommu=on iommu=pt”
9. #更新引导
10. update-grub

重新启动

六：安装驱动

下载驱动文件

1. wget https://mirrors.apqa.cn/d/vGPU/vgpu_unlock/drivers/NVIDIA-Linux-x86_64-510.47.03-vgpu-kvm-custom.run -P /opt

安装驱动

1. sh -c /opt/NVIDIA-Linux-x86_64-510.47.03-vgpu-kvm-custom.run –dkms

安装vgpu_unlock

1. cd /opt && git clone https://github.com/mbilker/vgpu_unlock-rs.git
2. cd /opt/vgpu_unlock-rs
3. cargo build –release
4. mkdir /etc/systemd/system/{nvidia-vgpud.service.d,nvidia-vgpu-mgr.service.d}
5. echo -e “[Service]\nEnvironment=LD_PRELOAD=/opt/vgpu_unlock-rs/target/release/libvgpu_unlock_rs.so” > /etc/systemd/system/nvidia-vgpud.service.d/vgpu_unlock.conf
6. echo -e “[Service]\nEnvironment=LD_PRELOAD=/opt/vgpu_unlock-rs/target/release/libvgpu_unlock_rs.so” > /etc/systemd/system/nvidia-vgpu-mgr.service.d/vgpu_unlock.conf
7. systemctl daemon-reload
