[dpdk-dev] DPDK with vhostuser - Issue in Testing with DPDK-Pktgen

[Abhijeet Karve]

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 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 à Flavor property
hw_­vif_mutliqueue_­enabled=­true à 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

Let me look at the problem and verify it is not a bug or something else.

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
