Commit 4f4c3b1397 added code to remember errors during freeing
of domain objects. This changed the output when testing scaled numbers
parsing in virsh-optparse. Adjust the expected output.
This removes the hacky extern global variable and modifies the
test code to properly create QEMU capabilities cache for QEMU
binaries used in our tests.

Our test data used a lot of different qemu binary paths and some
of them were based on downstream systems.
Note that there is one file where I had to add "accel=kvm" because
the qemuargv2xml code parses "/usr/bin/kvm" as virt type="kvm".

The virt type for QEMU can be modified by -machine attribute "accel"
so there is no need to have different QEMU binary paths.

Introduce STRICT_FRAME_LIMIT_CFLAGS that will be used for
production code and RELAXED_FRAME_LIMIT_CFLAGS for tests.
Raising the limit for tests allows building them with clang
with optimizations disabled.
This header file has been created so that we can expose
internal functions to the test suite without making them
public: those in qemu_capabilities.h bearing the comment
/* Only for use by test suite */
are obvious candidates for being moved over.
docs/schemas directory is meant for schemas which are installed on the
system. The schema for the news file does not need to be installed.
Store it along with the file it describes for simplicity.
Use the relative lookup specifier rather than the global one. Otherwise
only the first name would be looked up. Add a test case to cover the
scenario.

Depending on the architecture, requirements for ACPI and UEFI can
be different; more specifically, while on x86 UEFI requires ACPI,
on aarch64 it's the other way around.
Enforce these requirements when validating the domain, and make
the error message more accurate by mentioning that they're not
necessarily applicable to all architectures.
Several aarch64 test cases had to be tweaked because they would
have failed the validation step otherwise.
Now that the NO_ACPI and NO_HPET capabilities are set
automatically by virQEMUCapsInitQMPBasicArch() if
appropriate for the architecture, they shouldn't be
used manually to avoid masking bugs.
The capabilities used in test cases should match those used
during normal operation for the tests to make any sense.
This results in the generated command line for a few test
cases (most notably non-x86 test cases that were wrongly
assuming they could use -no-acpi) changing.
Sometimes it may be desired to validate individual files against a
schema. Refactor the data structures to unify them and introduce a new
macro DO_TEST_FILE(schema, xmlfile) which will test the XML file against
the given schema file.
CPU features which change their value from disabled to enabled between
two calls to query-cpu-model-expansion (the first with no extra
properties set and the second with 'migratable' property set to false)
can be marked as enabled and non-migratable in qemuMonitorCPUModelInfo.
Since the code consuming qemuMonitorCPUModelInfo currently ignores the
migratable flag, this change is effectively changing the CPU model
advertised in domain capabilities to contain all features (even those
which block migration). And this matches what we do for QEMU older than
2.9.0, when we detect all CPUID bits ourselves without asking QEMU.
As a result of this change
<cpu mode='host-model'>
<feature name='invtsc' policy='require'/>
</cpu>
will work with all QEMU versions. Such CPU definition would be forbidden
with QEMU >= 2.9.0 without this patch.

If calling query-cpu-model-expansion on the 'host'/'max' CPU model with
'migratable' property set to false succeeds, we know QEMU is able to
tell us which features would disable migration. Thus we can mark all
enabled features as migratable.

not. This patch adds support for storing such features in

Pool types that have the VIR_STORAGE_POOL_SOURCE_NAME flag set
allow omitting the <name> element and instead fill out the pool name
from the <source><name> element.
Relax the schema to make <name> optional for these pools.
Expressing that at least one of these is required is out of scope
of the schema.
This reverts commit c2e60ad0e5.
Turns out this check is excessively strict: there are ways
other than <memtune><hard_limit> to raise the memory locking
limit for QEMU processes, one prominent example being
tweaking /etc/security/limits.conf.

QEMU allows for TSC frequency to be explicitly set to enable migration
with invtsc (migration fails if the destination QEMU cannot set the
exact same frequency used when starting the domain on the source host).
Libvirt already supports setting the TSC frequency in the XML using
<clock>
<timer name='tsc' frequency='1234567890'/>
</clock>
which will be transformed into
-cpu Model,tsc-frequency=1234567890
QEMU command line.

The test takes
x86-cpuid-Something-guest.xml CPU (the CPU libvirt would use for
host-model on a CPU described by x86_64-cpuid-Something.xml without
talking to QEMU about what it supports on the host)
and updates it according to CPUID data from QEMU:
x86_64-cpuid-Something-enabled.xml (reported as "feature-words"
property of the CPU device)
and
x86_64-cpuid-Something-disabled.xml (reported as "filtered-features"
property of the CPU device).
The result is compared to
x86_64-cpuid-Something-json.xml (the CPU libvirt would use as
host-model based on the reply from query-cpu-model-expansion).
The comparison is a bit tricky because the *-json.xml CPU contains fewer
disabled features. Only the features which are included in the base CPU
model, but listed as disabled in *.json will be disabled in *-json.xml.
The CPU computed by virCPUUpdateLive from the test data will list all
features present in the host's CPUID data and not enabled in *.json as
disabled. The cpuTestUpdateLiveCompare function checks that the computed
and expected sets of enabled features match.

Commit v3.1.0-26-gd60012b4e started filtering hle and rtm features from

The new command can be used to generate test data for virCPUUpdateLive.
When "cpu-cpuid.py diff x86-cpuid-Something.json" is run, it reads raw
CPUID data stored in x86-cpuid-Something.xml and CPUID data from QEMU
stored in x86-cpuid-Something.json to produce two more CPUID files:
x86-cpuid-Something-enabled.xml and x86-cpuid-Something-disabled.xml.
- x86-cpuid-Something-enabled.xml will contain CPUID bits present in
x86-cpuid-Something.json (i.e., enabled by QEMU for the "host" CPU)
- x86-cpuid-Something-disabled.xml will contain all CPUID bits from
x86-cpuid-Something.xml which are not present in
x86-cpuid-Something.json (i.e., CPUID bits which the host CPU
supports, but QEMU does not enable them for the "host" CPU)
