Xcode 15, which provides the compiler toolchain for building libvirt
on macOS has switched to a new linker that warns about duplicated
"-lblah" options on the ld commandline. In practice this is impossible
to prevent in a large project, and also harmless.
Fortunately the new ld command also has an option,
-no_warn_duplicate_libraries, that supresses this harmless/pointless
warning, meson has a simple way to check if that option is supported,
and libvirt's meson.build files already have examples of adding an
option to the ld commandline if it's available.

Scripts from the following list were installed with group write

virt-sanlock-cleanup, libvirt-guests.sh. This is very unusual and
in contrast with the way other scripts/binaries are installed.

The virt-qemu-sev-validate program will compare a reported SEV/SEV-ES
domain launch measurement, to a computed launch measurement. This
determines whether the domain has been tampered with during launch.
This initial implementation requires all inputs to be provided
explicitly, and as such can run completely offline, without any
connection to libvirt.
The tool is placed in the libvirt-client-qemu sub-RPM since it is
specific to the QEMU driver.

Libvirt provides QMP passthrough APIs for the QEMU driver and these are
exposed in virsh. It is not especially pleasant, however, using the raw
QMP JSON syntax. QEMU has a tool 'qmp-shell' which can speak QMP and
exposes a human friendly interactive shell. It is not possible to use
this with libvirt managed guest, however, since only one client can
attach to the QMP socket at any point in time. While it would be
possible to configure a second QMP socket for a VM, it may not be
an known requirement at the time the guest is provisioned.
The virt-qmp-proxy tool aims to solve this problem. It opens a UNIX
socket and listens for incoming client connections, speaking QMP on
the connected socket. It will forward any QMP commands received onto
the running libvirt QEMU guest, and forward any replies back to the
QMP client. It will also forward back events.
$ virsh start demo
$ virt-qmp-proxy demo demo.qmp &
$ qmp-shell demo.qmp
Welcome to the QMP low-level shell!
Connected to QEMU 6.2.0
(QEMU) query-kvm
{
"return": {
"enabled": true,
"present": true
}
}
Note this tool of course has the same risks as the raw libvirt
QMP passthrough. It is safe to run query commands to fetch information
but commands which change the QEMU state risk disrupting libvirt's
management of QEMU, potentially resulting in data loss/corruption in
the worst case. Any use of this tool will cause the guest to be marked
as tainted as an warning that it could be in an unexpected state.
Since this tool introduces a python dependency it is not desirable
to include it in any of the existing RPMs in libvirt. This tool is
also QEMU specific, so isn't appropriate to bundle with the generic
tools. Thus a new RPM is introduced 'libvirt-clients-qemu', to
contain additional QEMU specific tools, with extra external deps.

Instead of creating an empty object and then setting keys one
at a time, it is possible to pass a dict object to
configuration_data(). This is nicer because it doesn't require
repeating the name of the cfg_data object over and over.
There is one exception: the 'conf' object, where we store values
that are used directly by C code. In that case, using a dict
object is not feasible for two reasons: first of all, replacing
the set_quoted() calls would result in awkward code with a lot
of calls to format(); moreover, since code that modifies it is
sprinkled all over the place, refactoring it would probably
make things more complicated rather than simpler.

'cmdEvent' along with all the helper functions it needs is ~950 LOC.
Move it out from virsh-domain.c to virsh-domain-event.c along with the
completer function so that the new module doesn't have to expose any new
types.
Semantically this creates a new category in 'virsh help' but all other
behaviour stays the same.

sysconfig files are owned by the admin of the host. They have the
liberty to put anything they want into these files. This makes it
difficult to provide different built-in defaults.
Remove the sysconfig file and place the current desired default into
the service file.
Local customizations can now go either into /etc/sysconfig/name
or /etc/systemd/system/name.service.d/my-knobs.conf
Attempt to handle upgrades in libvirt.spec.
Dirty files which are marked as %config will be renamed to file.rpmsave.
To restore them automatically, move stale .rpmsave files away, and
catch any new rpmsave files in %posttrans.

Right now we're unconditionally adding RPATH information to the
installed binaries and libraries, but that's not always desired.
autotools seem to be smart enough to only include that information
when targeting a non-standard prefix, so most distro packages
don't actually contain it; moreover, both Debian and Fedora have
wiki pages encouraging packagers to avoid setting RPATH:
https://wiki.debian.org/RpathIssuehttps://fedoraproject.org/wiki/RPath_Packaging_Draft
Implement RPATH logic that Does The Right Thing™ in the most
common cases, while still offering users the ability to override
the default behavior if they have specific needs.
