Commit Message

Cole Robinson Jan. 23, 2019, 9:32 p.m. UTC 
Add controller type='virtio-serial' model handling for virtio
transitional devices. Ex:

  <controller type='virtio-serial' model='virtio-transitional'/>

* "virtio-transitional" maps to qemu "virtio-serial-pci-transitional"
* "virtio-non-transitional" maps to qemu "virtio-serial-pci-non-transitional"

Please invert this, same as for hostdevs and input devices, so that
it looks like

  case VIR_DOMAIN_DEVICE_CONTROLLER:
      if (device.data.controller->type == VIR_DOMAIN_CONTROLLER_TYPE_VIRTIO_SERIAL)
          return 0;
      ...

With that addressed, and of course with the usual caveats around
formatting model='virtio',

Oh, I see now that you add another branch in the following commit,
which of course makes the above not applicable.

You can either leave it as is or turn it into a switch statement,
the latter being my personal preference.
