也就是在 GRUB_CMDLINE_LINUX_DEFAULT 里面添加 vfio-pci.ids=8086:56a0. 这表示给内核模块 vfio-pci 设置参数 ids. 其中 8086:56a0 是设备的 PCI 编号, 在上一步查看 IOMMU 分组时可以获得. 如果有多个设备, 以逗号 , 分隔, 比如 vfio-pci.ids=8086:56a0,103c:8136.然后重新生成 GRUB 配置文件: 重启...

Maybe make sure the host does not touch the device by adding vfio-pci.ids=MANU:DEVI to your kernel parameters (or /etc/modprobe/ configuration files), where MANU:DEVI is the ID of the device that is shows when you use lspci -n. If you need to move the ...
