Fallout or a pile yak shavings from the series to move the controller
validation from command line building into domain xml validation:
https://www.redhat.com/archives/libvir-list/2018-January/msg00188.html
This series grabs the first patch from the other series that was
essentially already ACK'd, but instead of heading down the path of
"working around" the fact that SCSI controller model may not be
set after domain post processing, this series builds up a series
of changes to implement altering the SCSI controller model during
device post processing rather than waiting for the validation phase
to "cheat" and alter a local model value temporarily.
The first 4 patches are relatively straightforward and don't change
any of the outputs. Starting with patch 5, things get a bit more
interesting. Patch 6 is where the conversion to set the default
model for SCSI controllers starts... Patch 7 is where things got
a bit tricky w/r/t the implicit controller... Patches 8 and 9 just
perform cleanup from that setting.
If this is accepted - I'll go back to the other series to adjust
and repost; otherwise, we can determine whether the other series
is necessary or if we're just happy with the way things are.

New subject: [libvirt] [PATCH 1/9] qemu: Split qemuDomainSetSCSIControllerModel
Rather than one function serving two purposes, let's split out the
else condition which is checking whether the model can be used
during command line building based on the capabilities.

New subject: [libvirt] [PATCH 2/9] conf: Rework and rename virDomainDeviceFindControllerModel
As it turns out virDomainDeviceFindControllerModel was only ever
called for SCSI controllers using VIR_DOMAIN_CONTROLLER_TYPE_SCSI
as a parameter.
So rename to virDomainDeviceFindSCSIController and rather than
return a model, let's return a virDomainControllerDefPtr to let
the caller reference whatever it wants.

New subject: [libvirt] [PATCH 3/9] qemu: Introduce qemuDomainFindSCSIControllerModel
Rather than repeat multiple steps in order to find the SCSI
controller model, let's combine them into one helper that will
return either the model from the definition or the default
model based on the capabilities.
This patch adds an extra check/error that the controller
that's being found actually exists. This just clarifies that
the error was because the controller doesn't exist rather
than the more generic error that we were unable to determine
the model from qemuDomainSetSCSIControllerModel when a -1
was passed in and the capabilities were unable to find one.

New subject: [libvirt] [PATCH 5/9] qemu: Fetch/save the default SCSI controller model during hotplug
If we're going to add a controller to the domain, let's set the
default SCSI model value if we cannot find another SCSI controller
already present.
NB: Requires updating the live output test data since the model
will now be formatted.

New subject: [libvirt] [PATCH 7/9] conf: Allow configuration of implicit controller model
When an implicit controller is added, the model is defined as -1
(IOW: undefined). So, if an implicit SCSI controller was added,
can set the model to the default value if the underlying hypervisor
supports it.

Now that post parse processing handles setting the SCSI controller
model, there's no need to call qemuDomainGetSCSIControllerModel to
get the "default controller" when building the command line controller
string or when assigning the spaprvio address since the controller
model value will already be filled in.

New subject: [libvirt] [PATCH 9/9] qemu: Update qemuDomainFindSCSIControllerModel return
Now that the controller model is updated during post parse callback,
this code no longer needs to fetch the model based on the capabilities
and can just return the model directly if the controller is found.
Removal of @qemuCaps cascades through various callers which are now
updated to not pass the capabilities.

The first 4 patches are relatively straightforward and don't change
any of the outputs. Starting with patch 5, things get a bit more

perform cleanup from that setting.

Could be nicer to just add an implicit controller with the correct
model.
Understood; however, how do you propose to accomplish that in
domain_conf code that's supposed to be hypervisor agnostic?
It's not like we can pass around a qemuCaps so that when
virDomainDefMaybeAddController can call the get default model function.
This ended up being the least offensive way I could determine would
accomplish the task even though it.
The other thought I had was jiggling the order of the call to
virDomainDefPostParseCommon to before the iteration of the devices
(virDomainDeviceInfoIterateInternal), but doing that scared me more than
taking the option to follow how serials and videos handled similar
adjustments after post parse was called.
In any case, thanks for the speedy review. I'll push what's here and
maybe someone else will propose some other brilliant suggestion.
