Hello,

I am trying to connect a virtual machine with a openvswitch using DPDK  
for performance, as you can see in the next figure.

I do not have any problem connecting with 10G NICs, but I do have when  
it comes to QEMU. I am nor pretty sure how to connect qemu with ovs.

As far as I know, I think that I have to use MEMNIC or Ivshmem, but I  
cannot find much information about how to do it.

Could someone explain to me how can it be done?

Thank you in advanced.
