Commit Message

Cole Robinson Jan. 17, 2019, 5:52 p.m.
Add new <memballoon> model values for virtio transitional devices. Ex:

  <memballoon model='virtio-transitional'/>

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

You didn't add the "Since: 5.1.0" here.

I'd sort these new <value>s right after "virtio".

Same comment as for other VIR_ENUM_IMPL() calls, and also I'd sort
the values as described above.

See comments on the previous patch for why I don't think this is
correct; either way, it should have been part of *that* patch, no?
