Thank you so much for this, using virtio drivers in DPDK has been messy and 
unpleasant in the past, and you clearly wrote a lot of nice new code to help 
improve it all.

Previously I'd reported a bug, where all RTE virtio drivers I tried (A and B, 
because I did not know C existed), failed to work with the virtio-net 
interfaces exposed in VirtualBox, due to various strange errors, and they all 
only worked with the virtio-net interfaces from qemu.

I wanted to find out if we managed to fix this other problem, because I would 
really like to use the Vagrant VM deployment tool (https://www.vagrantup.com/) 
to distribute my open-source DPDK based application to everyone in the 
open source community.

The better the out-of-box experience of practical community-created DPDK-based 
real-life example applications similar to mine, the more adoption of DPDK and 
better DPDK community we will be able to have as time marches forward.

If we could manage to get it to work in VirtualBox, then I could surely help 
do some app-level testing on the new code, if we could see it in a test branch 
or test repo somewhere I could access it.

Sincerely,
Matthew Hall
