Previous incomplete RFC here:

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
Changes since v2:
* Some prep patches merged
* filesystem model dropped the -9p naming, now uses virtio-{non-}transitional
like other devices
* Now uses a single capability QEMU_CAPS_VIRTIO_PCI_NON_TRANSITIONAL
which is set whenever any of the -transitional or -non-transitional
devices are present.
* Add a formatdomain section 'Virtio transitional devices' and reference
it from each relevant device section
* if virtio-transitional specified, and qemu is too old but has the
disable_X options, convert it to explicit
disable-legacy=off,disable-modern=off
* Misc small changes pointed out in review
Thanks,
Cole

I realize I'm the one who suggested this name in the first place :/
but the "NON" part is... Not very useful when you think about it.
So we could just as well call this
QEMU_CAPS_VIRTIO_PCI_TRANSITIONAL
instead and save a few bytes.
Whether you feel like renaming it or not,

New subject: [libvirt] [PATCH v3 03/17] conf: Add <disk model='virtio-{non-}transitional'/>
<disk> devices lack the model= attribute which is used by
most other device types. bus= mostly acts as one, but it
serves other purposes too like determing what target=
prefix to use, and for matching against controller type=
values.
Extending bus= to handle additional virtio transitional
devices will complicate apps lives, and it isn't a clean
mapping anyways. So let's bite the bullet and add a new
<disk model=X/> attribute, and wire up common handling
for virtio and virtio-{non-}transitional

devices</a></h4>
+
+ <p>
+ <span class="since">Since 5.1.0</span>, some of QEMU's
virtio devices,
+ when used with PCI/PCIe machine types, accept the following
+ <code>model</code> values:
+ </p>
+
+ <dl>
+ <dt><code>virtio-transitional</code></dt>
+ <dd>This instructs libvirt to always place the device in a conventional
+ PCI slot. The device can work with a virtio 0.9 or virtio 1.0
+ guest driver.
+ </dd>
+ <dt><code>virtio-non-transitional</code></dt>
+ <dd>
+ The device can only work with a virtio 1.0 guest driver.
+ </dd>
+ <dt><code>virtio</code></dt>
+ <dd> If the device is plugged into a PCIe slot, it acts as a
+ virtio-non-transitional device. If plugged into a conventional PCI slot,
+ it will function as a virtio-transitional device. This logic only
+ applies to devices that support the transitional models; for other
+ devices, <code>virtio</code> behavior will be different.
+ </dd>
+ </dl>

I'd reword this a bit to highlight the fact that protocol
compatibility is the main point of these devices, and slot assignment
stems from it. Something like
This device can work both with virtio 0.9 and virtio 1.0 guest
drivers, so it's the best choice when compatibility with older
guest operating systems is desired. libvirt will plug the device
into a conventional PCI slot.
+
<dt><code>virtio-non-transitional</code></dt>
+ <dd>
+ The device can only work with a virtio 1.0 guest driver.
In the same vein as the above,
This device can only work with virtio 1.0 guest drivers, and it's
the recommended option unless compatibility with older guest
operating systems is necessary. libvirt will plug the device into
either a PCI Express slot or a conventional PCI slot based on the
machine type, resulting in a more optimized PCI topology.
+ </dd>
+ <dt><code>virtio</code></dt>
+ <dd> If the device is plugged into a PCIe slot, it acts as a
+ virtio-non-transitional device. If plugged into a conventional PCI slot,
+ it will function as a virtio-transitional device. This logic only
+ applies to devices that support the transitional models; for other
+ devices, <code>virtio</code> behavior will be different.
And here too,
This device will work like a <code>virtio-non-transitional</code>
device when plugged into a PCI Express slot, and like a
<code>virtio-transitional</code> device otherwise; libvirt will
pick one or the other based on the machine type. This is the best
choice when compatibility with libvirt versions older than 5.1.0
is necessary, but it's otherwise not recommended to use it.
The idea behind these suggestions is that we should help the user
understand the various trade-offs and pick the value that better
suits their needs.

New subject: [libvirt] [PATCH v3 06/17] conf: Add <hostdev model='virtio-{non-}transitional'/>
qemu vhost-scsi devices map to XML roughly like:
<hostdev mode='subsystem' type='scsi_host'>
<source protocol='vhost' wwpn=X/>
</hostdev>
To support vhost-scsi-pci-{non-}traditional in qemu, we
need to to extend the SCSI Host hostdev XML to handle
model= value. This matches the XML model= format used
for mediated devices. This is just the domain_conf bits
and some XML test cases.
Use of virtio-X naming here does not match the hostdev
protocol=vhost nor does it match the qemu vhost-X device
naming, however it's more consistent with all other
model= names in this area, and also matches the
inconsistency of <vsock> devices which use model=virtio
but map to vhost-vsock on the qemu commandline

New subject: [libvirt] [PATCH v3 07/17] qemu: Support hostdev model=virtio-{non-}transitional
Add <hostdev> protocol=vhost model handling for virtio transitional
devices. Ex:

You still need to make sure QEMU_CAPS_DEVICE_VIRTIO_RNG is present
when the model is virtio-(non-)transitional.

Nit, but for other devices so far you've put the _TRANSITIONAL
case first, so please do the same here :)
With all of the above addressed,

New subject: [libvirt] [PATCH v3 09/17] conf: Add <filesystem model='virtio-{non-}transitional'/>
<filesystem> devices lack the model= attribute which is used by
most other device types. To eventually support
virtio-9p-pci-{non-}traditional in qemu, let's add a standard
model= attribute. The accepted values are:
- virtio
- virtio-transitional
- virtio-non-transitional

If we wanted to be super-duper safe, we could do
if (model) {
if ((def->model = virDomainFSModelTypeFromString(model)) < 0 ||
def->model == VIR_DOMAIN_FS_MODEL_DEFAULT) {
virReportError(VIR_ERR_CONFIG_UNSUPPORTED,
_("unknown model '%s'"), model);
goto error;
}
}
to prevent people from using
<filesystem model='default'>
...
</filesystem>
and same for disks and other devices for which we're introducing
the concept of model just now. But it's probably okay even if we
don't want to go the extra mile.
Either way,

New subject: [libvirt] [PATCH v3 11/17] qemu: Support memballoon model=virtio-{non-}transitional
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"

New subject: [libvirt] [PATCH v3 12/17] qemu: Support vsock model=virtio-{non-}transitional
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"

New subject: [libvirt] [PATCH v3 13/17] conf: Add <input model='virtio-{non-}transitional'/>
<input> devices lack the model= attribute which is used by
most other device types. To eventually support
virtio-input-host-pci-{non-}traditional in qemu, let's add
a standard model= attribute. This just adds the domain_conf
wiring

Same comment as 9/17 as far as parsing the model is concerned.

Since def->model is optional, I think this would be a bit more
legible as
if (def->model) {
const char *model = virDomainInputModelTypeToString(def->model);
if (!model) {
virReportError(VIR_ERR_INTERNAL_ERROR,

goto cleanup;
}
virBufferAsprintf(buf, " model='%s'", model);
}
but either way is fine.

New subject: [libvirt] [PATCH v3 16/17] qemu: Support scsi controller model=virtio-{non-}transitional
Add <controller type='scsi' model handling for virtio transitional
devices. Ex:
<controller type='scsi' model='virtio-transitional'/>
* "virtio-transitional" maps to qemu "virtio-scsi-pci-transitional"
* "virtio-non-transitional" maps to qemu
"virtio-scsi-non-transitional"
The naming here doesn't match the pre-existing model=virtio-scsi.
The prescence of '-scsi' there seems kind of redundant as we have
type='scsi' already, so I decided to follow the pattern of other
patches and use virtio-transitional etc.

New subject: [libvirt] [PATCH v3 16/17] qemu: Support scsi controller model=virtio-{non-}transitional
On Fri, 2019-02-08 at 17:12 -0500, Cole Robinson wrote:
Add <controller type='scsi' model handling for virtio
transitional
devices. Ex:
<controller type='scsi' model='virtio-transitional'/>
* "virtio-transitional" maps to qemu "virtio-scsi-pci-transitional"
* "virtio-non-transitional" maps to qemu
"virtio-scsi-non-transitional"
The naming here doesn't match the pre-existing model=virtio-scsi.
The prescence of '-scsi' there seems kind of redundant as we have
type='scsi' already, so I decided to follow the pattern of other
patches and use virtio-transitional etc.

This did not apply correctly for me on top of 1620bb0a3050373d059b0,
but after regenerating output files the resulting diff looks sane
enough so I'll assume everything is fine and you'll take care of it
before pushing anyway.

As mentioned during the previous rounf of reviews, this hunk (and
the resulting output file) belong in a separate patch. Please make
ure you split these unrelated changes off before pushing.
With that addressed,

qemu patches, queued for qemu 4.0.0:

Previous libvirt discussion around this:
https://www.redhat.com/archives/libvir-list/2018-August/msg01073.html
Changes since v2:
* Some prep patches merged
* filesystem model dropped the -9p naming, now uses virtio-{non-}transitional
like other devices
* Now uses a single capability QEMU_CAPS_VIRTIO_PCI_NON_TRANSITIONAL
which is set whenever any of the -transitional or -non-transitional
devices are present.
* Add a formatdomain section 'Virtio transitional devices' and reference
it from each relevant device section
* if virtio-transitional specified, and qemu is too old but has the
disable_X options, convert it to explicit
disable-legacy=off,disable-modern=off
* Misc small changes pointed out in review
Oh, and this definitely deserves to be mentioned in the release
notes! Can you please post a 18/17 or a separate patch that adds
the corresponding entry?

Thanks for the reviews, I fixed all the issues you pointed out and
pushed the patches here:
https://github.com/crobinso/libvirt/tree/virtio-v4
I'll wait to push until after 5.2.0 is out, so we have a longer window
to tweak things if eduardo's responses change anything, and to discuss
the controller type=scsi model=virtio patch I think you have pending...
Oh, and this definitely deserves to be mentioned in the release
notes! Can you please post a 18/17 or a separate patch that adds
the corresponding entry?
I'll send one after I push the commits
Thanks,
Cole

Thanks for the reviews, I fixed all the issues you pointed out and
pushed the patches here:
https://github.com/crobinso/libvirt/tree/virtio-v4
I'll wait to push until after 5.2.0 is out, so we have a longer window
to tweak things if eduardo's responses change anything, and to discuss
the controller type=scsi model=virtio patch I think you have pending...
I meant version 5.1.0
