[libvirt] [PATCH 08/18] qemu: Support rng model=virtio-{non-}transitional
Cole Robinson
crobinso at redhat.com
Thu Jan 17 17:52:35 UTC 2019
Add new <rng> model values for virtio transitional devices. Ex:
<rng model='virtio-transitional'>
...
</rng>
* "virtio-transitional" maps to qemu "virtio-rng-pci-transitional"
* "virtio-non-transitional" maps to qemu "virtio-rng-pci-non-transitional"
