[libvirt] [PATCH 6/6] qemu: Support rng model=virtio-{non-}transitional
Cole Robinson

Sun Jan 13 23:12:08 UTC 2019
Add new <rng> model values for virtio transitional devices
* "virtio-transitional" maps to qemu "virtio-rng-pci-transitional"
* "virtio-non-transitional" maps to qemu "virtio-rng-pci-non-transitional"
