Hi Abhijeet, To be able to use vhostuser multiqueue support you will need to have following software versions.
OpenStack: Liberty Qemu: 2.5 Libvirt: > 1.2.17 DPDK: 2.2 Ovs: either the tip of 2.5 branch or master branch Setting hw_vif_mutliqueue_enabled=true Image property won't have any effect with your current configuration.

We have setup DPDK with vhostuser in AllinOne setup on following software platform. _____________ Openstack: Kilo Distribution: Ubuntu 14.04 OVS Version: 2.4.0 DPDK 2.0.0 _____________ In our Openstack OVS-DPDK set up, we are spawning 2 instance on same host with Ubuntu and running DPDK-pktgen in one of the VM and measuring traffic between VMs of same host. VMs spec are 8GB of memory and 4 core, we are using one port for pktgen application. Please fine the VM huge page setting as well, HugePages_Total: 1024 HugePages_Free: 896 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB Please find the below command we are using, ./app/app/$RTE_TARGET/pktgen -c 0f -n 3 --proc-type auto --socket-mem 256 -b 0000:00:03.0 -- -P -m "[1-3].0" Regardless of the cores whatever we are passing here(-m "[1-3].0"), the traffic is sending via only one core, remaining 2 cores are idle. We have added specific property as well to the images we are using, hw:vif_multiqueue_enabled=true --> Flavor property hw_vif_mutliqueue_enabled=true --> Image property Still we got the same issue on the application. >From logs, . . . . . ** Dev Info (rte_virtio_pmd:0) ** max_vfs : 0 min_rx_bufsize : 64 max_rx_pktlen : 9728 max_rx_queues : 1 max_tx_queues: 1 . . . . . Kindly suggest us something on this regard if we need to tune anything on Openstack end or in pktgen application.
