[libvirt] [PATCH v2 20/25] qemu: Support vsock model=virtio-{non-}transitional
Cole Robinson
crobinso at redhat.com
Wed Jan 23 21:32:48 UTC 2019
Add <vsock> model handling for virtio transitional devices. Ex:
<vsock model='virtio-transitional'>
...
</vsock>
* "virtio-transitional" maps to qemu "vhost-vsock-pci-transitional"
* "virtio-non-transitional" maps to qemu "vhost-vsock-pci-non-transitional"
