[libvirt] [PATCH 10/18] qemu: Support filesystem model=virtio-{non-}transitional
Cole Robinson
crobinso at redhat.com
Thu Jan 17 17:52:37 UTC 2019
Add <filesystem> model handling for virtio transitional devices. Ex:
<filesystem type='mount' model='virtio-transitional'>
...
</filesystem
* "virtio-transitional" maps to qemu "virtio-9p-pci-transitional"
* "virtio-non-transitional" maps to qemu "virtio-9p-pci-non-transitional"
