This series adds the beginnings of support for virtio-transitional
and virtio-non-transitional qemu devices.
qemu patches, queued for qemu 4.0.0:
https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg00923.html
Previous libvirt discussion around this:
https://www.redhat.com/archives/libvir-list/2018-August/msg01073.html
Long story short we need to expose these options so apps have a
usable way to support rhel6 + virtio + q35.
This series only covers exposing the associated device models
for disk and rng devices to make sure I'm on the right track.
serial, net, scsi, input-host, balloon 9p, vsock, vhost-scsi
still need to be implemented. Those should follow the rng
example, except vhost-scsi may need to be a different approach.
The main RFC bits here are:
* The disk approach. danpb and I briefly discussed on IRC adding
new bus= values vs a new model= attribute. We decided model=
is the lesser of two evils, since bus= handling in apps is
tied with target= generation, so adding new virtio-X bus=
values will cause more work for apps. These patches add
a <disk model=X/> attribute
* The XML and naming. Previous discussions seemed to favor adding
new model-style values rather than a 'transitional' attribute
or similar. So these patches add model='virtio-transitional'
and model='virtio-non-transitional'
* The PCI address handling. I just mapped virtio-non-transitional
to imply plain PCI addressing. I think that's all we need but
I'm not positive so I'd appreciate a review of that approach.
