Cole Robinson Jan. 23, 2019, 9:32 p.m.
Add new <interface> model handling for virtio transitional devices. Ex:

<interface>
  <model type='virtio-transitional'/>
</interface>

* "virtio-transitional" maps to qemu "virtio-net-pci-transitional"
* "virtio-non-transitional" maps to qemu "virtio-net-pci-non-transitional"

Same comment as the previous patch, but I assume you're gonna
either change all of them or none of them, so I'm not gonna repeat
it for every patch :)
