I have no proof it will work perfectly, as I never got to use the virtio PMDs because neither works in VirtualBox (developer-friendly / desktop virtualization). But there is a script included in DPDK, dpdk_nic_bind.py, which should let you configure this more intelligently on a per-VNIC basis. You could try something similar to this: export RTE_SDK="${build_directory}/external/dpdk" export RTE_TOOLS="${RTE_SDK}/tools" export RTE_NIC_BIND="${RTE_TOOLS}/dpdk_nic_bind.py" "${RTE_NIC_BIND}" --status | fgrep "${PCI_ID}" "${RTE_NIC_BIND}" -b none "${PCI_ID}" "${RTE_NIC_BIND}" -b igb_uio "${PCI_ID}" "${RTE_NIC_BIND}" --status | fgrep "${PCI_ID}" Good Luck!
