Hi Ian, Good to hear from you,
Yea, I am running DPDK sample application 'l2fwd'. But I am not running it on the virtual machine(guest). I am running it on the same Ubuntu machine (bare metal host) where I have installed Qemu-KVM and OVS_DPDK. I am using OVS version 2.10.90 and DPDK 11.7.4 LTS in the host machine. I am attaching all the screen shots again with this mail for your reference. Thanks in advance. Look forward to hear from you.
