6a9b336be1 qemuxml2argvtest: Drop 'qemu-4.1' variants of all audio tests
Minimum qemu version will be bumped to qemu-4.2 so we no longer need to
care about configuring audiodevs via the environment variables.

1f14dbccbc tests: Mock virQEMUCapsProbeHVF()
Successfully returning without doing anything is what the
function already does on non-Apple platforms.

When building on macOS, however, the check for HVF availability
will be performed. When running on bare metal, that will result
in the QEMU_CAPS_HVF flag being added to the virQEMUCaps
instance, and a bunch of error messages along the lines of

  In 'tests/qemucapabilitiesdata/caps_6.2.0.x86_64.xml':
  Offset 7557
  Expect [c]
  Actual [hvf'/>
    <flag name=‘c]

showing up.

Up until now we hadn't noticed because our CI jobs run in VMs,
where HVF support is not available.

ede39c1fc6 tests: Pass the flat_namespace option to the linker
This fixes vircryptotest on macOS 12 (Monterey).

The test relies on library injection (using DYLD_INSERT_LIBRARIES)
to replace the normal random functions with functions giving predictable
results, defined in virrandommock.c. However, using DYLD_INSERT_LIBRARIES
only works when building with flat namespaces.

Adding the -Wl,-flat_namespace option to the linker fixes the problem.
The option was already defined in the top-level meson.build, but had been
forgotten in the test linker arguments.

In a recent commit of v8.5.0-85-g430ab88ab1 I've made domaincaps
XML report supported TPM versions. This was done by calling
virTPMSwtpmSetupCapsGet(). But this function isn't mocked and
thus domaincapstest calls the real implementation, which tries to
execute swtpm_setup binary. This fails, because
virFindFileInPath() is mocked in such way that it returns NULL
for anything else than qemu-*.

Anyway, while the real binary is not executed after all, we
should mock the function which tries to execute it so that
predictable result is returned.

f7baee531a conf: Validate virDomainMemoryDef::targetNode
Almost all of memory models we currently support allow setting
virDomainMemoryDef::targetNode so that the memory module is
associated with given guest NUMA node. And we do have a check
whether the requested node is within bounds, but it's executed
only when building QEMU's cmd line. Move it into validation
phase.

While this commit is moving the validation to a place that does
not validate all the possible code paths, it's okay, because only
the explicit memory device has user-configurable target node
which could break the assumption.

578ac25c6a conf: support stateless UEFI firmware
Normally when an UEFI firmware is marked as read-only, an associated
NVRAM file will be created. Some builds of UEFI firmware, however, wish
to remain stateless and so will be read-only, but never have any NVRAM

is introduced on the <loader/> element.

There are rather a large number of permutations to consider.

265d49896d qemu: Generate cmd line for guestReset
QEMU offers two attributes for handling reset requests of an USB
host device: guest-reset and guest-resets-all. When combined they
act as follows:

1) guest-reset=false
   The guest is not allowed to reset the physical USB device.

2) guest-reset=true,guest-resets-all=false
   The guest is allowed to reset the device when it is not yet
   initialized (aka no USB bus address assigned). Usually this results
   in one guest reset being allowed. This is the default behavior.

3) guest-reset=true,guest-resets-all=true
   The guest is allowed to reset the device as it pleases.

Now, there's a clear 1:1 mapping with our representation of
guestReset, so generating cmd line is trivial.

0738d339a3 qemu_capabilities: Track usb-host.guest-resets-all capability
We will need two attributes of usb-host device to set:
guest-reset and guest-resets-all. The former was introduced in
QEMU v4.0.0-rc0~56^2 and the other in v4.2.0-rc1~9^2. Hence,
track the latter only as it's only starting from that commit when
QEMU has both attributes.

85ea114016 conf: Introduce @guestReset to hostdev's <source/>
Some USB devices have a buggy firmware that either crashes on
device reset, or make the device unusable in some other way.
Fortunately, QEMU offers a way to skip device reset either
completely, or if device is not initialized yet. Expose this
ability to users under:

    <hostdev mode='subsystem' type='usb'>
      <source guestReset='off'/>
    </hostdev>

dcfbfffd6a tests: Fix qemu replies wrt usb-host properties
My commit of v6.9.0-rc1~457 was a bit too harsh. While it served
its purpose (adding usb-host.hostdevice capability) it has a side
effect: because I copied reply from qemu-5.1.0 to older .replies
files one might now think that say qemu-3.1.0 supports both
.guest-reset and .guest-resets-all properties. But in fact it
doesn't. There are three problematic properties:

1) guest-reset, introduced in v4.0.0-rc0~56^2
2) guest-resets-all introduced in v4.2.0-rc1~9^2
3) suppress-remote-wake introduced in v5.0.0-rc0~148^2~4

Remove these properties from versions that could not have had
them.

Extend the test for io_uring to also test startup policy.

Since the actual logic for dropping disks is in the host preparation
phase, thus skipped for tests we can use any file path.

Add a case also for 'file' backing to have all cases covered.
