Hi Neeraj,

I would suggest to add an extra interface or two so you keep the first one for 
the needs of the VM itself - this could be simpler to work/debug with. I assume 
the hardware type you configure is supported by DPDK ?

Also, as an alternative approach, for initial experiments, maybe simpler to use 
the AF_PACKET interfaces, you can see an example on how to configure them in 
https://wiki.fd.io/view/VPP/Configure_VPP_As_A_Router_Between_Namespaces
