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.
Regards
Przemek

Subject: DPDK with vhostuser - Issue in Testing with DPDK-Pktgen
Dear Przemek, Sean & Sugesh,
It would be great if get your valuable inputs for the below listed issue. 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
: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.
Thanks & Regards
Abhijeet Karve
