There are a number of cases in which we want to test both the

XML.
The way this is currently implemented is ad-hoc, and involves
symlinking the input XML as well as coming up with an
alternative name for the ABI_UPDATE variant: in most cases the
-abi-update suffix is added, but since this is not enforced
there are a couple of cases where we do something else instead.
To make things simpler and more consistent, implement the

Rather than always binding to the vfio-pci driver, use the new
function virPCIDeviceFindBestVFIOVariant() to see if the running
kernel has a VFIO variant driver available that is a better match for
the device, and if one is found, use that instead.
virPCIDeviceFindBestVFIOVariant() function reads the modalias file for
the given device from sysfs, then looks through
/lib/modules/${kernel_release}/modules.alias for the vfio_pci alias
that matches with the least number of wildcard ('*') fields.
The appropriate "VFIO variant" driver for a device will be the PCI
driver implemented by the discovered module - these drivers are
compatible with (and provide the entire API of) the standard vfio-pci
driver, but have additional device-specific APIs that can be useful
for, e.g., saving/restoring state for migration.
If a specific driver is named (using <driver model='blah'/> in the
device XML), that will still be used rather than searching
modules.alias; this makes it possible to force binding of vfio-pci if
there is an issue with the auto-selected variant driver.

The long-deprecated use of <driver name='vfio|xen|kvm'/> in domain xml
for <hostdev> devices was only ever necessary during the period when
libvirt (and the Linux kernel) supported both VFIO and "legacy KVM"
styles of hostdev device assignment for QEMU. This became pointless
many years ago when legacy KVM device assignment was removed from the
kernel, and support for that style of device assignment was completely
disabled in the libvirt source in 2019 (commit
v5.6.0-316-g2e7225ea8c).
Nevertheless, there were instances of <driver name='vfio'/> in the
unit test data that were then (unnecessarily) propagated to several
more tests over the years. This patch cleans out those unnecessary
explicit settings of driver name='vfio' in all QEMU unit test data,
proving that the attribute is no longer (externally) needed. (A later
patch which adds a 2nd attribute to the <driver> element will include

Xen only supports a single type of PCI hostdev assignment, so it is
superfluous to have <driver name='xen'/> peppered throughout the
config. It *is* necessary to have the driver type explicitly set in
the hostdev object before calling into the hypervisor-agnostic "hostdev
manager" though (otherwise the hostdev manager doesn't know whether it
should do Xen-specific setup, or VFIO-specific setup).
Historically, the Xen driver has checked for "default" driver name
(i.e. not set in the XML), and set it to "xen', during the XML
postparse, thus guaranteeing that it will be set by the time the
object is sent to the hostdev manager at runtime, but also setting it
so early that a simple round-trip of parse-format results in the XML
always containing an explicit <driver name='xen'/>, even if that
wasn't specified in the original XML.
The QEMU driver *doesn't* set driver.name during postparse though;
instead, it waits until domain startup time (or device attach time for
hotplug), and sets the driver.name then. The result is that a
parse-format round trip of the XML in the QEMU driver *doesn't* add in
the <driver name='vfio'/>.
This patch modifies the Xen driver to behave similarly to the QEMU
driver - the PostParse just checks for a driver.name that isn't
supported by the Xen driver, and any explicit setting to "xen" is
deferred until domain runtime rather than during the postparse, thus
Xen domain XML also doesn't get extraneous <driver name='xen'/>.
This delayed setting of driver.name of course results in slightly
different xml2xml parse-format results, so the unit test data is
modified accordingly.

Currently we only append a newline to 'actual' if 'expected'
(as loaded from file) already ends in a newline, but that
results in inconsistent behavior.
For example, some of the test files used by virhostcputest are
newline-terminated and some aren't. If we were to remove
existing newlines from those files or add them where they
aren't present, the test would still pass, and even using
VIR_TEST_REGENERATE_OUTPUT=1 wouldn't change them back.
Make things consistent by ensuring that 'actual' is always
newline-terminated. The only exception is when 'actual' is
completely empty: in that case, we want the file to be actually
empty, not contain a single empty line. query-jobs-empty.result
in qemumonitorjsondata/ is an example of this being used.

because the required selinux policies are not yet widely available, we
have disabled nbdkit support on rpm builds for all distributions before

Unfortunately, this makes it more difficult to test nbdkit support.
After someone updates to the necessary selinux policies, they would also

DO_TEST_CPUID(arch, host, json) is a multipart test. It consists of the
following tests:
- cpuTestHostCPUID()
- cpuTestGuestCPUID(with JSON_* flag)
- cpuTestCPUIDSignature()
- DO_TEST_JSON():
- if json==JSON_MODELS:
- cpuTestGuestCPUID(without JSON_* flag)
- cpuTestJSONCPUID()
- cputestJSONSignature()
Notice that for tests with json==JSON_MODELS, cpuTestGuestCPUID() is
actually called twice but with different arguments. The first one passes
JSON_MODELS to the test function, while the second one passes 0.
The main difference in behavior when calling cpuTestGuestCPUID() with or
without the flag is that in the first case, it parses the captured qemu
output from $ARCH-cpuid-$CPU.json. It extracts the cpu model list from
that JSON, and uses that to filter out possible cpu models to match.
In other words, it tries to match the cpu to a model that was supported
by the qemu version that was used to generate this JSON file. When it
finds a match, it generates a cpu definition and compares the xml form
of that definition with the file $ARCH-cpuid-$CPU-guest.xml.
When called without the JSON_MODELS flag, it simply attempts to match it
against the full libvirt cpu map and doesn't attempt to filter out any
matches based on the JSON qemu cpu model list. After it finds a match,
it generates an xml definition for the cpu and compares it to the same
file listed above. So if these two invocations disagree on the cpu match
(e.g. because libvirt has added a cpu model to its cpu map that matches
better than one that was supported by the version of qemu that generated
the JSON file) the test will fail.
This duplicate call to cpuTestGuestCPUID() was originally added in
commit 49c945a6f5. The original
justification for that commit was to fix test failures when the Qemu
driver was disabled. But since DO_TEST_JSON() is #defined empty when
qemu is disabled, this particular invocation would not even be executed
in this scenario, so it doesn't seem relevant.

While glibc provides qsort(), which usually is just a mergesort,
until sorting arrays so huge that temporary array used by
mergesort would not fit into physical memory (which in our case
is never), we are not guaranteed it'll use mergesort. The
advantage of mergesort is clear - it's stable. IOW, if we have an
array of values parsed from XML, qsort() it and produce some
output based on those values, we can then compare the output with
some expected output, line by line.
But with newer glibc this is all history. After [1], qsort() is
no longer mergesort but introsort instead, which is not stable.
This is suboptimal, because in some cases we want to preserve
order of equal items. For instance, in ebiptablesApplyNewRules(),
nwfilter rules are sorted by their priority. But if two rules
have the same priority, we want to keep them in the order they
appear in the XML. Since it's hard/needless work to identify
places where stable or unstable sorting is needed, let's just
play it safe and use stable sorting everywhere.
Fortunately, glib provides g_qsort_with_data() which indeed
implement mergesort and it's a drop in replacement for qsort(),
almost. It accepts fifth argument (pointer to opaque data), that
is passed to comparator function, which then accepts three
arguments.
We have to keep one occurance of qsort() though - in NSS module
which deliberately does not link with glib.

The current message can be misleading, because it seems to suggest

What actually happens most of the time, however, is that despite
having multiple firmwares of the right type to choose from, none
of them is suitable because of lacking some specific feature or
being incompatible with some setting that the user has explicitly
enabled.
Providing an error message that describes exactly the problem is
not feasible, since we would have to list each candidate along
with the reason why we rejected it, which would get out of hand
quickly.
As a small but hopefully helpful improvement over the current
