[libvirt] [PATCH v3 05/17] qemu: Support interface model=virtio-{non-}transitional
Cole Robinson

Fri Feb 8 22:11:56 UTC 2019
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"
