Inside of virschematest.c there's testSchemaDir() which iterates
over dentries in given directory but skips some files: those
without ".xml" suffix, hidden files, symlinks, etc.
Now, symlinks are detected as g_lstat() + S_ISLNK() combo which
works, except it fails to compile on mingw where is no concept of
symlinks. Replace the combo with a call to virFileIsLink() which
at least allows us to compile cleanly on mingw.

qemu supports this enlightenment since version 7.10.
From the qemu commit:
Hyper-V specification allows to pass parameters for certain hypercalls
using XMM registers ("XMM Fast Hypercall Input"). When the feature is
in use, it allows for faster hypercalls processing as KVM can avoid

Introduce tests to verify that the 'ps2' feature is correctly parsed
when given either 'dirty' XML from a user or 'clean' canonical XML,
as produced by libvirt. This also tests the transformation from libvirt's
internal state to the aforementioned canonical form and to a QEMU
command line.
As a bonus, we also test some known bad configurations:
- When user explicitly adds ps2 bus inputs, but also explicitly disables
the 'ps2' feature.
- When user explicitly enables the 'vmport' feature, but also explicitly
disables the 'ps2' feature. This is not supported by QEMU and will
result in vmport device not being created without emitting any warning
or error.

This capability tells us whether given QEMU binary supports the

controller emulation.
A few facts:
- This option was introduced in QEMU 7.0 and defaults to 'on'
- QEMU versions before 7.0 enabled i8042 controller emulation implicitly
- This option (and i8042 controller emulation itself) is only supported
by descendants of the generic PC machine type (e.g. i440fx, q35, etc.)

Introduce a test case for sysinfotest. The data was obtained by

dmidecode -q -t 0,1,2,3,4,11,17
Now, the expected output fits almost perfectly, except for OEM
strings where the third string looks nothing like in the
dmidecode output. This is because of testDMIDecodeDryRun() which
overwrites the third OEM string (see v6.5.0-rc1~214 for more
info). But that's okay for now.
Speaking of OEM strings, it's worth noticing two 'OEM Strings'
sections in the dmidecode output. This is causing some troubles

The aim of pstore device is to provide a bit of NVRAM storage for
guest kernel to record oops/panic logs just before the it

watchdog so that the logs can be inspected after the watchdog
rebooted the machine. While Linux kernel (and possibly Windows
too) support many backends, in QEMU there's just 'acpi-erst'
device so stick with that for now. The device must be attached to
a PCI bus and needs two additional values (well, corresponding
memory-backend-file needs them): size and path. Despite using
memory-backend-file this does NOT add any additional RAM to the
guest and thus I've decided to expose it as another device type
instead of memory model.

The latter causes it to be considered eligible for the

pointer value such as 0x1 or 0x2 from virDomainHostdevSubsysSCSIVHost's
point of view. This leads to a segmentation fault when it attempts to free
wwpn.
While setting sgio does not appear to crash, it shares the same flawed logic
as setting rawio.
