Hello Team
I'm able to solve the issue.I had missed configuring Huge pages on ubuntu.
[Mooney, Sean K] Im glad you have resolved your issue. The hugepage requirement is documented
here for future reference https://docs.openstack.org/ocata/networking-guide/config-ovs-dpdk.html
unfortunetly there is currently no good way to detect this edge case due to how nova,neutron and os-vif interact with each
other and ovs so documenting this requirement Is the best we can do.
Thanks for the time.
Regards
Abhishek Jain

Hi Sean,Stokes

Thanks for looking this out,below are the inline answers to your queries..


Could you provide more detail on the components you are running (OVS and DPDK versions etc.).

I'm using OVS version 2.4.1 on ubuntu 14.04.5 LTS.



Just to clarify, do you mean the stats for the device within the VM (i.e. your using something like ifconfig to check the rx/tx stats) or do you mean the OVS DPDK stats for the ports connected to the VMs themselves (for example vhost ports

With Tx/Rx count not increasing on VM,I'm referring to the VM itself and I'm checking the same by running ifconfig inside VM.



Do you mean your able to ping the IP of the VMs internally to them i.e. ping local host essentially?
Yes,I'm able to ping localhost from respective VMs.

Do you mean your able to ping the IP of the VMs internally to them i.e. ping local host essentially?

CC'ing Sean Mooney as I'm not the most experienced with OpenStack and Sean might be able to help.

Thanks
