A default deployment on modern distros uses modular daemons but
switching back to the monolithic daemon, while not recommended,
is still considered a perfectly valid option.
For a monolithic daemon deployment, the upgrade to libvirt 9.2.0
or newer works as expected; a subsequent call to dnf autoremove,
however, results in the libvirt-daemon package being removed and
the deployment no longer working.
In order to avoid that situation, mark the libvirt-daemon as
recommended.
This will unfortunately result in it being included in most
installations despite not being necessary, but considering that
the alternative is breaking existing setups on upgrade it feels
like a reasonable tradeoff.
Moreover, since the dependency on libvirt-daemon is just a weak
one, it's still possible for people looking to minimize the
footprint of their installation to manually remove the package
after installation, mitigating the drawbacks of this approach.

For historical reasons (i.e. unknown reason) we put channel
sockets into a path derived from cfg->libDir which is a path that
survives host reboots (e.g. /var/lib/libvirt/...). This is not
necessary and in fact for session daemon creates a longer prefix:
XDG_CONFIG_HOME -> /home/user/.config
XDG_RUNTIME_DIR -> /run/user/1000
Worse, if host is rebooted suddenly (e.g. due to power loss) then
we leave files behind and nobody will ever remove them.
Therefore, place the channel target dir into state dir.

A <channel/> device is basically an UNIX socket into guest.
Whatever is sent from the host, appears in the guest and vice
versa. But because of that, the length of the path to the socket
is important (underscored by fact that we derive the path from
domain short name). But there are still cases where we might not
fit into UNIX_PATH_MAX limit (usually 108 characters), because
the path is derived also from other variables, e.g.
XDG_CONFIG_HOME for session domains.
There are two components though, that are needless: "/target/"
and "domain-" prefix. Drop them. This is safe to do, because
running domains have their path saved in status XML and even
though paths are dropped on migration, they are not part of guest
ABI and thus we are free to change them.

In most cases the replacement is straightforward, with the
biggest difference being that we now schedule restarts during
%pre instead of %post. This also means that we can get rid of
%post for most packages, reducing the number of scriptlets that
need to run during install/upgrade.
Notable exceptions are libvirt-guests.service, where we stop
using the standard systemd macros to adopt our custom ones, as
well as the virtlogd and virtlockd services, where the reload
operation is moved from %postun to %posttrans.

systemd provides a number of standard RPM macros but they don't
quite satisfy our requirements, as evidenced by the fact that we
have already built some custom tooling around them.
Scenarios that the standard macros don't cover and that we're
already addressing with our custom ones:
* for some services (libvirtd, virtnetworkd, virtnwfilterd)
there are multiple conditions that might lead to a restart,
and we want to make sure that they're not needlessly
restarted several times per transaction;
* some services (virtlogd, virtlockd) must not be restarted
during upgrade, so we have to reload them instead.
Issues that neither the standard macros nor our custom ones
address:
* presets for units should be applied when the unit is first
installed, not when the package that contains it is.
The package split that happened in 9.1.0 highlighted why this
last point is so important: when virtproxyd and its sockets
were moved from libvirt-daemon to the new libvirt-daemon-proxy
package, upgrades from 9.0.0 caused presets for them to be
applied.
On a platform such as Fedora, where modular daemons are the
default, this has resulted in breaking existing deployments in
at least two scenarios.
The first one is machines that were configured to use the
monolithic daemon, either because the local admin had manually
changed the configuration or because the installation dated
back to before modular daemons had become the default. In this
case, virtproxyd.socket being enabled resulted in a silent
conflict with libvirtd.socket, which by design shares the same
path, and thus a completely broken setup.
The second one is machines where virtproxy-tls.socket, which is
disabled by default, had manually been enabled: in this case,
applying the presets resulted in it being disabled and thus a
loss of remote availability.
Note that these are just two concrete scenarios, but the problem
is more generic. For example, if we were to add more units to an
existing package, per the current approach they wouldn't have
their presets applied.
The new macros are designed to avoid all of the pitfalls
mentioned above. As a bonus, they're also simpler to use: where
the current approach requires restarts and other operations to
be handled separately, the new one integrates the two so that,
for each scriptlet, a single macro call is needed.

The current implementation pretty much assumes that targets
where modular daemons are the default will stick with that
configuration, as will targets where they're not, or that
changes to these defaults will be performed by the admin after
the packages have been installed.
This is unnecessarily limiting: for example, on a target that
defaults to using the monolithic daemon, it's entirely possible
to create a local preset such as
# /etc/systemd/system-preset/00-virt.preset
disable libvirtd.service
disable libvirtd*.socket
enable virtqemud.service
to opt into a modular daemon deployment. The opposite is of
course also true. We shouldn't get in the way of these
reasonable use cases.

Only 'recommend' passt during installation though, since it is not

There is no need to add in a build-time "WITH_PASST" option (IMO),
since it adds very little to the size of the code - "PASST" (the path
to the binary) will just be set to "passt", so if someone does manage
to build and install passt on an older version of Fedora or RHEL, it

The libvirt-daemon subpackage contains libvirt-guests.sh script (used by
libvirt-guests service), which requires virsh to actually work. But
since dynamic libraries were separated from libvirt-client to
libvirt-libs more than 6 years ago, libvirt-daemon no longer requires
virsh to be installed. So unless libvirt-client is explicitly installed
(either manually or by installing the libvirt meta package),
libvirt-guests will not work.
Just adding libvirt-client as a dependency of libvirt-daemon would go
against the original idea behind splitting libvirt-client: users may not
want to install or use any client binaries on the host where the daemon
runs (either they just use various language bindings or access the
daemon remotely). To solve this we could possibly turn libvirt-daemon
into an empty package and separate the daemons and libvirt-guests into
subpackages to make sure we support both use cases, but marking
libvirt-client as Recommended for libvirt-daemon does the same job in a
much simpler way.

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

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.
