This series aim is to change the qemu machvirt video type default to
virtio, but rather than continue to hack things into place in
domain_conf.c, this rearranges things to allow drivers to set a
video type default.
Patches 1 is a small prep change in the qemu code
Patches 2-4 are the plumbing to allow drivers to set their own default
Patch 5 is the actual default change
https://bugzilla.redhat.com/show_bug.cgi?id=1404112
v2:
Rebase
Push a few prep patches
Drop the (virDomainVideoType) annotations
Add patch #1
Cole Robinson (5):
qemu: whitelist valid video types
conf: domain: add VIDEO_TYPE_DEFAULT
conf: domain: move video type validation to DeviceDefValidate
qemu: Set default video type in qemu PostParse
qemu: Default to video type=virtio for machvirt

NACK, we prefer to listing all possible values for typed switch. It
forces a contributor to look at all places where that switch is used
in order to consider whether that place should be updated or not.

NACK, we prefer to listing all possible values for typed switch. It

in order to consider whether that place should be updated or not.
Thanks for the review. I don't really see the benefit of listing all
VIDEO_TYPE in this case. If a new TYPE is added, either it's:
1) Something qemu supports and the developer is adding qemu support for it.
There's no way they can miss extending this switch to whitelist the new type,
since otherwise their qemu XML will be rejected at parse time. It's the first
functional thing in src/qemu they have to change
2) Something being added for a non-qemu driver. Maybe qemu supports it, maybe
it doesn't, but regardless the developer isn't on the hook for implementing it
for qemu. In this case, adding the new VIDEO_TYPE to the blacklist is slightly
better code documentation, but it adds no runtime benefits over the 'default:'
case. Plus there's potential issues if the user forgets to add the new TYPE
(like TYPE_GOP currently but the impact is small, start time vs parse time
failure). We could enforce the switch type checking with (virDomainVideoType)
cast but that could lead to build breakage if the dev isn't compiling the qemu
driver.
In some cases I think it makes sense to list all enum values but IMO this
isn't one of them.
Thanks,
Cole

Sorry for the late reply, I was solving the chardev reconnect issues.
1) Something qemu supports and the developer is adding qemu support
for it.

That's true but having the typed switch that forces you to cover all
values without default would save you the trouble of building libvirt,
starting the daemon and defining new domain. It would fail while
building. Yes, most of the developers adding such feature would
probably extend that switch but still if you forget to do it this would
help you realize that right away.
2) Something being added for a non-qemu driver. Maybe qemu supports
it, maybe
it doesn't, but regardless the developer isn't on the hook for implementing it
for qemu. In this case, adding the new VIDEO_TYPE to the blacklist is slightly
better code documentation, but it adds no runtime benefits over the 'default:'
case. Plus there's potential issues if the user forgets to add the new TYPE
(like TYPE_GOP currently but the impact is small, start time vs parse time
failure). We could enforce the switch type checking with (virDomainVideoType)
cast but that could lead to build breakage if the dev isn't compiling the qemu
driver.
So instead of using default I would actually prefer casting the
video->type to virDomainVideoType so if forces you to always consider
this place.

This hunk should not be required, but I've checked the code that fills
in domain capabilities and we claim that every video model is supported.
Well that's wrong and should be fixed.
Anyway, the patch itself is good.

Sigh :) Ignore this comment, the code works correctly, this is a test
where we format all capabilities.

New subject: [libvirt] [PATCH v2 5/5] qemu: Default to video type=virtio for machvirt
On Sun, Aug 27, 2017 at 11:04:42AM -0400, Cole Robinson wrote:
arm/aarch64 -M virt on KVM doesn't and will never work with
standard
VGA card emulation. The recommended method is to use type=virtio, so
let's make it the default for video devices without an explicit type
set by the user
Missing a period at the end of sentence.
I would put an empty line after the BZ link.

It is possible to skip the graphics and use <video/> instead. This
would make the test only about video device but I'm fine with having
the graphics in the test as well.
