1.修改系统Grub参数
参考官方文档 qm_pci_passthrough 开启 PVE 硬件直通功能。
使用 SSH 工具登录到 PVE 服务器,编辑系统 Grub 的配置文件 /etc/default/grub :
## 编辑 Grub 配置文件
nano /etc/default/grub
在 nano 编辑器对话框中修改 GRUB_CMDLINE_LINUX_DEFAULT 参数,注意命令中间的空格:
## Intel 处理器添加参数
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on"
根据官方文档的说明,AMD 处理器下硬件直通功能将会自动打开,否则需要手动修改 Grub 配置文件:
## AMD 处理器添加参数
GRUB_CMDLINE_LINUX_DEFAULT="quiet amd_iommu=on"
修改并保存后,需要更新系统 Grub :
## 更新系统 Grub
update-grub
2.加载系统内核模块
修改系统 /etc/modules 配置文件,增加必要的系统模块:
## 编辑系统配置文件
nano /etc/modules
在配置文件末尾输入以下内容:
vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd
将配置文件保存,并重启 PVE 服务器。
PVE 服务器重启完成后,再次使用 SSH 工具登录,并使用以下命令检查硬件直通状态:
## 检查系统硬件直通状态
dmesg | grep -e DMAR -e IOMMU -e AMD-Vi
检查 IOMMU 、 Directed I/O 或 Interrupt Remapping 的启用状态。
