v1 libvirt patches:
https://www.redhat.com/archives/libvir-list/2019-January/msg00593.html
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
Long story short we need to expose these options so apps have a
usable way to support rhel6 + virtio + q35. This series exposes
the new devices as model= values. This required adding new
model= attributes for several devices. See v1 posting for a summary
of the XML changes introduced, mostly it's adding virtio-transitional
and virtio-non-transitional to existing model= enums, and adding
model= XML attributes for devices that don't have them (disk, fs,
input)
Changes from v1:
- <filesystem> models are now named virtio-9p, virtio-9p-transitional,
virtio-9p-non-transitional. This is to avoid ambiguity as in the near
future we will likely add virtio-fs <filesystem> support
- Cleanup and prep work is separated into separate patches and front
loaded into the series.
- qemu caps additions are separated from the qemu_command.c patches,
and squashed together upfront.
- virDomainDeviceSetData is added to make it easier to compose a
virDomainDeviceDef on the fly. This is used for the transitional cli
building but can be useful elsewhere too, but that's for another
series.
- Lots of small improvements and fixes suggested by Andrea.
Thanks,
Cole

I agree that would be nicer, but I dug a bit deeper: This code path is
triggered in two major different ways: as a part of validating a full
DomainDef, but also for validating an _individual_ device which hasn't
been added to a DomainDef yet. The latter path is via
virDomainDeviceDefParse which is called in hotplug situations. So to be
completely correct this function can't validate against def->memballoon
because it may not have been set yet.

Documentation doesn't match signature: use either 'devicedata'
or 'data' in both cases. I personally prefer the latter, but either
one is fine :)
Additionally, please move both the implementation...

New subject: [libvirt] [PATCH v2 08/25] qemu: command: Make BuildVirtioDevStr more generic
Switch qemuBuildVirtioDevStr to use virDomainDeviceSetData: callers
pass in the virDomainDeviceType and the void * DefPtr. This will
save us from having to repeatedly extend the function argument
list in subsequent patches.

This seems excessive, is there a plan to retire the transitional
devices? I don't expect anyone creating a QEMU build that e.g.:
a) supports virtio-rng-pci-transitional but not virtio-rng-pci-non-transitional
b) supports virtio-scsi-pci-transitional but not virtio-input-host-pci-transitional
For the disable-legacy property, we only have
QEMU_CAPS_VIRTIO_PCI_DISABLE_LEGACY, that is checked on multiple (but
not all possible) PCI devices.

That's a very good point! We could have a single capability
QEMU_CAPS_VIRTIO_PCI_NON_TRANSITIONAL
that is set if any out of a bunch of {,non-}transitional devices
is present, and key everything else off that...
Eduardo, do you think we might ever get in trouble if we did that?
For example, because of QEMU dropping transitional devices but
leaving non-transitional devices in?

I believe eduardo is offline for the next few weeks, so I'll make this
change in the next version to just track a single capability
QEMU_CAPS_VIRTIO_PCI_NON_TRANSITIONAL
We can always add the fine grained capabilities later if needed.

Sounds good, let's just make sure he has a chance to veto the
approach *before* it ends up in a stable libvirt release, to avoid
compatibility headaches in case we were wrong O:-)

If there's a chance I'm going to have redo the series and edit every
qemu_command.c patch again to use the fine grained capabilities, then
I'll just wait for his response.
But I don't really think it's necessary. Presumably if -transitional or
-non-transitional devices are compiled out of qemu, the equivalent
disable-legacy/disable-modern config should be rejected too. So if our
qemuCaps detection is wrong, and we determine
-transitional/-non-transitional is supported when it is actually
compiled out, the user request is never going to work anyways. So even
if eduardo suggests using the fine grained capabilities, we could do it
as a follow on patch.
The one place it may actually matter is in domaincapabilities; we don't
want to incorrectly report that virtio-transitional is supported for a
device, because apps may make programmatic decisions based on what we
report. So we could defer the disk domaincapabilities patch until we get
a clear answer. FWIW that was my original motivation for going fine
grained with the qemuCaps values, I expect to eventually expose all of
them in domaincapabilities.
Thanks,
Cole

I just found this message on my inbox, sorry for missing it.
Predicting the future is hard, and predicting the decisions of
every downstream packagers of QEMU is harder. But I don't expect
anybody to compile out just a few of the (-non)-transitional
devices. This unlikely scenario doesn't seem worth the extra
complexity of a large set of new capability flags.

New subject: [libvirt] [PATCH v2 11/25] 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

<disk> devices lack the model= attribute which is used by

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

Yeah, that sounds like a very good idea. We will probably want to
make it its own section, too, so that we can link to it from each
of the devices that support (non-)transitional VirtIO.

Okay i'll add that in its own series. Having a separate section is a
nice idea to reduce duplication

While this is absolutely correct and we should definitely not error
out if the transitional device is not available, perhaps for the
benefit of someone looking at the generated QEMU command line for
debugging purposes we could do the same as below and also print
disable-legacy=off,disable-modern=off
if the corresponding options are available - we would still not
error out if they aren't, of course. Sounds reasonable?

Makes for shorter lines which is nice but kind of offsets the benefit of
converting to virDomainDeviceSetData in the first place...

You're definitely using qemuCaps now, so you should remove
ATTRIBUTE_UNUSED from the parameter in the function signature.

While this is absolutely correct and we should definitely not error
out if the transitional device is not available, perhaps for the
benefit of someone looking at the generated QEMU command line for
debugging purposes we could do the same as below and also print
disable-legacy=off,disable-modern=off
if the corresponding options are available - we would still not
error out if they aren't, of course. Sounds reasonable?
Good point, i'll change it

Maybe add something like
/* Even if the QEMU binary doesn't support the non-transitional
* device, we can still make it work by manually disabling legacy
* VirtIO and enabling modern VirtIO */
here.

Can please you use the same kind of switch statement you later use
for eg. input devices here?
ACK to all these changes too

Makes for shorter lines which is nice but kind of offsets the benefit of
converting to virDomainDeviceSetData in the first place...
A bit, yes: if you did this, then the only use you'd get out of
the virDomainDeviceDef you just reconstructed would be getting a
virDomainDeviceInfo out of it... On the other hand, that also means
you wouldn't be basically open-coding virDomainDeviceGetInfo() in
yet another place.
As I said, pick whichever you like the most :)

Same comment as the previous patch, but I assume you're gonna
either change all of them or none of them, so I'm not gonna repeat
it for every patch :)

New subject: [libvirt] [PATCH v2 14/25] 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

qemu vhost-scsi devices map to XML roughly like:
<hostdev mode='subsystem' type='scsi_host'>

</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

Same comment as for disks, and this time it would make even more
sense considering just how incredibly long some of the lines get
when you have to traverse the entire structure all in one go...

Using a switch statement here would be nice too.

New subject: [libvirt] [PATCH v2 16/25] qemu: Support rng model=virtio-{non-}transitional
Add new <rng> model values for virtio transitional devices. Ex:
<rng model='virtio-transitional'>
...
</rng>
* "virtio-transitional" maps to qemu "virtio-rng-pci-transitional"
* "virtio-non-transitional" maps to qemu
"virtio-rng-pci-non-transitional"

Of course you now need s/model_supported/modelIsSupported/g now.
Aside from that and the usual stuff everything looks good, so

New subject: [libvirt] [PATCH v2 17/25] conf: Add <filesystem model='virtio-9p-{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-9p
- virtio-9p-transitional
- virtio-9p-non-transitional
The divergence in naming from other *-transitional values is
because we expect to support virtio-fs in the future.

I thought there was rough consensus on having separate 'model'
and 'protocol' attributes, with the former using the same values
as other VirtIO devices, but looking through the archives I've
found
https://www.redhat.com/archives/libvir-list/2019-January/msg00799.html
where you said you were going this route for v2... Sorry I didn't
notice earlier and thus didn't have a chance to yell :)
I think being consistent with other devices is more important than,
for lack of a better term, "marketing" virtio-fs.
Moreover, management applications like virt-manager and Cockpit
will probably present this as a single drop-down to users, so it
hardly matters that it ultimately ends up being translated to two
separate attributes and what the corresponding values are.

Okay I'll go with the protocol= syntax danpb suggested

Althought I guess the protocol= syntax is really only interesting once
we have another use case like usb-mtp or virtio-fs wired up. So I guess
I'll just do model=virtio|virtio-transitional|virtio-non-transitional

...
</filesystem
* "virtio-9p-transitional" maps to qemu "virtio-9p-pci-transitional"
* "virtio-9p-non-transitional" maps to qemu
"virtio-9p-pci-non-transitional"

New subject: [libvirt] [PATCH v2 19/25] 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"

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.

New subject: [libvirt] [PATCH v2 24/25] 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.

If we add model='virtio' we should always translate it back to
'virtio-scsi'. It's not a new model or new feature, it's just a
different name for existing model and we should not break management
applications that are already using 'virtio-scsi'. It would be
basically only alias. The question is whether it's useful, if
management application starts using 'virtio' when creating new guest it
would still had to be able to parse 'virtio-scsi' and my guess is that
it would not help at all.

If we add model='virtio' we should always translate it back to
'virtio-scsi'. It's not a new model or new feature, it's just a
different name for existing model and we should not break management
applications that are already using 'virtio-scsi'. It would be
basically only alias.
Definitely.
The question is whether it's useful, if
management application starts using 'virtio' when creating new guest it
would still had to be able to parse 'virtio-scsi' and my guess is that
it would not help at all.
I agree that the value proposition is not that impressive once
you've established the above.
That said, implementing it is only going to take a couple of lines
of code and it will allow applications that can afford to require
very recent libvirt to only special-case SCSI controllers when
parsing the configuration, instead of both when parsing and when
formatting.
I guess I just don't see a reason *not* to implement it. But if
Cole doesn't want to go through with it that's fine, I can just
post patches later myself :)

Cole doesn't want to go through with it that's fine, I can just
post patches later myself :)
My reason for objection was to not bog down the patch series with
essentially tangential discussions. If I added the patch here, and it
prompted a big discussion, it could block the whole series (this should
all be committed as a single unit so apps can key off a single
domaincapabilities field or libvirt version to determine if
-transitional support is in place)
It's also kind of new territory to add a model that's essentially an
alias like pavel points out, which potentially deserves a wider
discussion, and buried in a big series isn't really the place IMO. Plus
I wanted to dig a bit into the archives to see why model=virtio-scsi
naming was chosen in the first place, maybe there was a specific
argument for that naming.
All that said, I'm not opposed to the idea and it is on my list to look
into after this series is committed. It's just very much a side issue
here IMO
Thanks,
Cole

This is why I suggested earlier that it could be its own separate
patch, to be either squashed into this one or dropped entirely based
on feedback.

Yeah, doing it as a follow-up works too, as long as we can squeeze
everything into the same libvirt release if we decide to go for it.

so that all the test suite changes we see in this one are a direct
consequence of adding the new information.

Long story short we need to expose these options so apps have a
usable way to support rhel6 + virtio + q35. This series exposes
the new devices as model= values. This required adding new
model= attributes for several devices. See v1 posting for a summary
of the XML changes introduced, mostly it's adding virtio-transitional
and virtio-non-transitional to existing model= enums, and adding
model= XML attributes for devices that don't have them (disk, fs,
input)
Changes from v1:
- <filesystem> models are now named virtio-9p, virtio-9p-transitional,
virtio-9p-non-transitional. This is to avoid ambiguity as in the near
future we will likely add virtio-fs <filesystem> support
- Cleanup and prep work is separated into separate patches and front
loaded into the series.
- qemu caps additions are separated from the qemu_command.c patches,
and squashed together upfront.
- virDomainDeviceSetData is added to make it easier to compose a
virDomainDeviceDef on the fly. This is used for the transitional cli
building but can be useful elsewhere too, but that's for another
series.
- Lots of small improvements and fixes suggested by Andrea.
Forgot to mention, another relevant change is adding disable-modern=off
alongside disable-legacy=on, from the v1 subthread with danpb and ehabkost
Thanks,
Cole
