Have you brought up VMs with vhost-user ports successfully? dpdkvhost receive function will not succeed until a VM with the associated socket is detected. Launch QEMU with the following (repeat for each dpdkvhostuser port): -chardev socket,id=char1,path=/usr/local/var/run/openvswitch/dpdkvhost0 -netdev type=vhost-user,id=mynet1,chardev=char1,vhostforce -device virtio-net-pci,mac=00:00:00:00:00:01,netdev=mynet1 Please see INSTALL.DPDK.md for further instructions. If you have already gotten this far, have you seen any errors? You can enable RTE_LIBRTE_VHOST_DEBUG=y in DPDK to get some more clues.
