[libvirt] [PATCH REBASE 0/2] qemu: Clean up PCI controller options
Rebase of https://www.redhat.com/archives/libvir-list/2017-December/msg00154.html on top of master, now that patch 1/3 has been merged as part of John's work to move controller checks from command line generation to guest validation.

Not quite sure I understand the need. The only capability not currently used in some way is QEMU_CAPS_I440FX_PCI_HOLE64_SIZE. I guess there's nothing wrong with adding them other than test bloat. Still there's nothing to "force" someone that adds some new thing to update one of the three if some new option/capability is added. Ironically adding (for example) QEMU_CAPS_Q35_PCI_HOLE64_SIZE to i440fx-* doesn't cause any failure. I didn't try other ones. BTW: This is what led me to determine that the qemuxml2argv isn't being built any more and a response to Dan's series. I'm not opposed to this being added, but do you think we should add something does the opposite check? That the wrong PCI adapter on the wrong machine? The wrong option on the wrong adapter is a question for the next patch though... John

The input configurations set all existing options for all PCI controllers, to see what ends up showing up in the output.
Not quite sure I understand the need. The only capability not currently used in some way is QEMU_CAPS_I440FX_PCI_HOLE64_SIZE.
The idea is that existing tests only cover valid PCI controller options being handled correctly, not what happens when you specify an option which is not relevant to the PCI controller at hand.
I guess there's nothing wrong with adding them other than test bloat. Still there's nothing to "force" someone that adds some new thing to update one of the three if some new option/capability is added.
That's correct. Can you think of a way to make sure that happens?
Ironically adding (for example) QEMU_CAPS_Q35_PCI_HOLE64_SIZE to i440fx-* doesn't cause any failure. I didn't try other ones.
Of course it wouldn't: capabilities are a property of the QEMU binary, and the same QEMU binary is used to run both i440fx and q35 guests. Even for something entirely outlandish like adding a q35-specific capability to a pSeries test you shouldn't see any failure unless you actually attempt to use the QEMU feature the capability is tied to.
I'm not opposed to this being added, but do you think we should add something does the opposite check? That the wrong PCI adapter on the wrong machine? The wrong option on the wrong adapter is a question for the next patch though...
We should already have at least *some* coverage for that, eg. pseries-serial-invalid-machine and similar. I'm certainly not volunteering to go over all controller and device and machine types and write tests for all combinations :) -- Andrea Bolognani / Red Hat / Virtualization

Well I understood you're going for a put the stake in the ground in order to supply that valid list of options for the pci controllers on the related machines.

and of course that got me to wondering if it was possible in any way to have some way that the "i440fx" xml2{xml|argv} to know that it's "covering" all it's known and supported relative options. Secondarily to know when someone adds something to a machine that won't support it before they get to the point of actually running and things falling over dead because of the wrong configuration provided. Nothing sprang quickly to mind to try other than adding comments which we all know are ignored anyway ;-0... I'm not against this patch going in, but if someone has agita over a small about of test bloat to list everything "currently" possible for a machine type then they should speak up!

We have something - good... John
Most of the options are only applicable to one or two controller types, so they should be filtered out everywhere else. This will reduce user confusion and, in at least one corner case, prevent guests from disappearing on daemon restart.

So, if I'm reading things correctly - rather than fail because someone set an option on a controller (and sometimes for a machine) for which it's not supported, the choice is to ignore the value and enforce the default. This does seem to go against what's been traditionally done (at least my recollection of it) for other XML options being wrongly applied to some other device. Even the bz is a big vague: Expected results: Schema for the 'target' field in <controller model='pci-bridge'> should not accept 'chassis' and 'port' parameters for 'q35' machine type But I'd read that as some sort of failure is expected rather than acceptance and quietly changing. Curious what other thoughts on this exist? At the very least be a bit more pointed in the commit message rather than just saying "filtered" it should be pointed out that if one is set, it's going to be cleared. I didn't see any of these in the ABI Stability tests so that's good!

Most of the options are only applicable to one or two controller types, so they should be filtered out everywhere else.
This will reduce user confusion and, in at least one corner case, prevent guests from disappearing on daemon restart.

So, if I'm reading things correctly - rather than fail because someone set an option on a controller (and sometimes for a machine) for which it's not supported, the choice is to ignore the value and enforce the default.
This does seem to go against what's been traditionally done (at least my recollection of it) for other XML options being wrongly applied to some other device.
Even the bz is a big vague:
Expected results: Schema for the 'target' field in <controller model='pci-bridge'> should not accept 'chassis' and 'port' parameters for 'q35' machine type
But I'd read that as some sort of failure is expected rather than acceptance and quietly changing.
Yeah, I'm not sure why I implemented it that way myself. I'll move everything to a Validate() sub-callback and error out if any unexpected option is set for a controller. That will make the test cases added in 1/2 slightly less useful, though, as it will error out on the first such option instead of showing that it's resetting all of them.

I prefer not embedding in a function knowledge about its callers, because callers change all the time. In this specific case, I guess the name is explicit enough that nobody would try calling it on a USB controller, so we can probably skip the check. -- Andrea Bolognani / Red Hat / Virtualization
