64dcb59756 domaincapstest: Use obviously fake firmware name in capabilities
The domain capabilities data feature a firmware section which is filled
by few entries. The entries used until now looked real and it was
suspicious that a x86_64 host was listing aarch64 firmware images which
should not happen.

Fill it by an obviously fake path as it's not actually interpreted in a
meaningful way.

a38ad6f687 cpu_s390: Implement getVendorForModel for IBM Z
When running "virsh domcapabilities" on a s390x host, all the CPU
models show up with vendor='unknown' - which sounds kind of weird
since the vendor of these mainframe CPUs is well known: IBM.
All CPUs starting with either "z" or "gen" match a real mainframe
CPU by IBM, so let's return the string "IBM" for those now.
The only remaining ones are now the artifical "qemu" and "max"
models from QEMU itself, so it should be OK to get an "unknown"
vendor for those two.

903ea9370d qemu_capabilities: Report Hyper-V Enlightenments in domcapabilities
Inside of qemuCaps (for the corresponding accelerator) we have
full host CPU expansion stored, among with supported Hyper-V
Enlightenments. To report them in the domain capabilities, we
just have to pick those starting with "hv-" and see if we know
them.

You may notice that neither of our domaincapsdata test shows any
enlightenment. This is because the test works by parsing
corresponding qemucapabilitiesdata/caps_*.xml file and none of
these store the full host CPU expansion (hostCPU.fullQEMU)
because that is runtime piece of information and not formatted
into virQEMUCaps XML.

vendor of each CPU model is our CPU map, which is considered internal

We also disallow users to clear the flags via the namespace property or

The change to the PPC64 test data originates from the fact that the
capability dump is not from the release version but is lacking one of

Because of v8.5.0-rc1~25 we are already faking TPM support for

The swtpm binary supports both TPM versions since its first

pretend only TPM-1.2 is available, QEMU-6.* has both TPM-1.2 and
TPM-2.0 and QEMU-7.0 and newer has only TPM-2.0 available.

dfba8b3645 qemucapabilitiestest: Add test data for the qemu-7.1 dev cycle on x86_64
Notable schema changes:

 - 'cluster-id' is now reported for CPU topology
 - 'display-update' QMP command added
 - 'main-loop' QOM object added with a whole set of properties
 - 'cpu0-id' field reported in SEV data
 - 'blockdev-change-medium' command now has 'force' property
 - 'screendump' QMP command now has a 'format' property
    - supported formats are 'ppm' and 'png'

48341b025a cpu_x86: Penalize disabled features when computing CPU model
For finding the best matching CPU model for a given set of features
while we don't know the CPU signature (i.e., when computing a baseline
CPU model) we've been using a "shortest list of features" heuristics.
This works well if new CPU models are supersets of older models, but
that's not always the case. As a result it may actually select a new CPU
model as a baseline while removing some features from it to make it
compatible with older models. This is in general worse than using an old
CPU model with a bunch of added features as a guest OS or apps may crash
when using features that were disabled.

On the other hand we don't want to end up with a very old model which
would guarantee no disabled features as it could stop a guest OS or apps
from using some features provided by the CPU because they would not
expect them on such an old CPU.

This patch changes the heuristics to something in between. Enabled and
disabled features are counted separately so that a CPU model requiring
some features to be disabled looks worse than a model with fewer
disabled features even if its complete list of features is longer. The
penalty given for each additional disabled feature gets bigger to make
longer list of disabled features look even worse.

b7f5ad4610 tests: Add capabilities for QEMU 7.0.0 on aarch64
The QEMU binary is built from the v7.0.0-rc2 tag.

This causes the argument to -device to be generated in JSON
format, same as what 1a691fe1c8 has done for x86_64.

c3d0236e67 tests: Update capabilities for QEMU 7.0.0 on ppc64
The QEMU binary is built from the v7.0.0-rc2 tag.

Some of the additional capabilities that show up are a
consequence of more features being enabled in this build than
in the one used to generate the replies initially.
