You need to keep PF on ixgbe and when VF shows up you need to bind VF to vfio-pci. If you don't have IOMMU enabled, you need to turn unsafe no-iommu mode by doing: echo Y | sudo tee /sys/module/vfio/parameters/enable_unsafe_noiommu_mode vfio-pci is absolute preference for kernel 4.4+, in both iommu and no-iommu mode. -- Damjan
