My first thought is that it is a DPDK issue, but more information is needed.
Could you please provide some more details?
- OvS, DPDK and QEMU versions you are using.
- The exact steps you perform in the guest before starting the testpmd 
application, specifically how do you bind the virtio interfaces to DPDK.

Thanks,

Mauricio V.
