We want to ignore all files except *.pl in build-aux directory, however
the unignore pattern "!/build-aux/*.pl" doesn't have any effect because
a previous "/build-aux/" pattern ignores the directory itself rather
than individual files in it.

If formatting NUMA topology fails, the function returns immediatelly,
but the buffer structure allocated on the stack references lot of
heap-allocated memory and that would get lost in such case.

qemuProcessVerifyHypervFeatures is supposed to check whether all
requested hyperv features were actually honored by QEMU/KVM. This is
done by checking the corresponding CPUID bits reported by the virtual
CPU. In other words, it doesn't work for string properties, such as
VIR_DOMAIN_HYPERV_VENDOR_ID (there is no CPUID bit we could check). We
could theoretically check all 96 bits corresponding to the vendor
string, but luckily we don't have to check the feature at all. If QEMU
is too old to support hyperv features, the domain won't even start.
Otherwise, it is always supported.

Without this patch, libvirt refuses to start a domain which contains

  <features>
    <hyperv>
      <vendor_id state='on' value='...'/>
    </hyperv>
  </features>

reporting internal error: "unknown CPU feature __kvm_hv_vendor_id.

This regression was introduced by commit v3.1.0-186-ge9dbe701, which
(by fixing the virCPUDataCheckFeature condition in
qemuProcessVerifyHypervFeatures) revealed an old bug in the feature
verification code. It's been there ever since the verification was
implemented by commit v1.3.3-rc1-5-g95bbe4bf, which effectively did not
check VIR_DOMAIN_HYPERV_VENDOR_ID at all.

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.

The contents of volname would be leaked if the function were
to be passed an invalid pooltype by the caller.

Make sure the memory is released instead.

This function runs an iscsi command and parses its output.
However, due to the nature of things, virISCSIExtractSession()

allocate new memory and overwrite the variable where we keep

Imagine that this function is called twice over the same disk
source. While in the first run all allocated memory is freed, not
all pointers are set to NULL (e.g. def->srcpool). So when called
again, these poitners are freed again resulting in double free.

QEMU_CHECK_MONITOR_* already logs the object and vm name

After restart of libvirtd the 'checkPool' method is supposed to validate
that the pool is online. Since libvirt then refreshes the pool contents
anyways just return whether the pool was supposed to be online so that
the code can be reached. This is necessary since if a pool does not
implement the method it's automatically considered as inactive.

We use the "vir" prefix pretty consistently in our
APIs, both external and internal, which made these
macros stood out.

For native gluster pools the <dir> field denotes a directory inside the
pool. For the actual pool name the <name> field has to be used.

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.

Add a test program called virstorageutiltest and test the gluster pool
detection code.

To allow testing of the algorithm, split out the extractor into a
separate helper.

The native gluster pool source list data differs from the data used for
attaching gluster volumes as netfs pools. Currently the only difference
was the format. Since native pools don't use it and later there will be
more differences add a more deterministic way to switch between the
types instead.

Validate that users don't try to disable vcpu 0.

Vcpu order is required to stay sequential. Clear the order on cpu
coldplug to avoid issues with removing vcpus out of sequence.

'next' is declared as 'ssize_t' so use '%zd'

Buggy condition meant that vcpu0 would not be iterated in the checks.
Since it's not hotpluggable anyways we would not be able to break the

The 'capacity' value (e.g. guest logical size) for a LUKS volume is
smaller than the 'physical' value of the file in the file system, so
we need to account for that.

When peeking at the encryption information about the volume add a fetch
of the payload_offset which is described as the offset to the start of
the volume data (in 512 byte sectors) in QEMU's QCryptoBlockLUKSHeader.

Then adjust the ->capacity appropriately when we determine that the
volume target encryption has a payload_offset value.

Add check for more than one RTA_OIF, even though this is rather
unlikely.

Get rid of the buggy switch / break as this code won't need to
handle more attributes.

Make sure every combination of ACPI and UEFI works, or fails to
work, as expected.

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.
