正常情况下
[root@localhost cloud_images]# lsmod | grep vfio vfio_pci 262144 0 vfio_virqfd 262144 1 vfio_pci vfio_iommu_type1 262144 0 vfio 262144 3 vfio_iommu_type1,vfio_pci
Error - no supported modules(DPDK driver) are loaded
只执行了modprobe vfio enable_unsafe_noiommu_mode=1
[root@localhost ~]# modprobe vfio-pci [root@localhost ~]# lsmod | grep vfio vfio_pci 262144 0 vfio_virqfd 262144 1 vfio_pci vfio_iommu_type1 262144 0 vfio 262144 2 vfio_iommu_type1,vfio_pci [root@localhost ~]#
