for Thiagos current need it really is even easier - You have a few places
you care about regarding dpdk
- mutliqueue for virtio-nics to use them from a guest
- shared huge page memory when using vhost_user
- vhost_user based nics + multiqueue for those

All of them have libvirt XML sections now, no commandline nor even
qemu-argv needed at all.
That is what I pointed to the serverguide for as I have examples of all
these sections there.
