For unmanaged ethernet <interface/>, it is user's responsibility
to set up the interface. And as such it can be just anything.
Therefore, it's (almost) impossible for the
virDomainInterfaceStats() API to tell whether RX/TX values need
to be swapped or copied verbatim into the return structure.

273c408899 tools: load CPU count and CPU SKU from libvirt

state. We can get the CPU count directly from libvirt's guest info. The
VMSA state can be constructed automatically if we query the CPU SKU from
host capabilities XML. Neither of these is secure, however, so this
behaviour is restricted.

676df5b358 tools: support automatically constructing SEV-ES vCPU state
The VMSA files contain the expected CPU register state for the VM. Their
content varies based on a few pieces of the stack

  - AMD CPU architectural initial state
  - KVM hypervisor VM CPU initialization
  - QEMU userspace VM CPU initialization
  - AMD CPU SKU (family/model/stepping)

The first three pieces of information we can obtain through code
inspection. The last piece of information we can take on the command
line. This allows a user to validate a SEV-ES guest merely by providing
the CPU SKU information, using --cpu-family, --cpu-model,
--cpu-stepping. This avoids the need to obtain or construct VMSA files
directly.

It will refuse to use a libvirt connection that is thought to be local

c43718ef67 Document caveats of 'VIR_DOMAIN_STATS_VM' group of statistics
The original patches adding the functionality neglected to add any form
of documentation for the stats fields returned for this group.

The stats are directly converted from qemu's 'query-stats(-schema)' QMP
command without any further interpretation. The 'query-stats-schema' has
the following disclaimer:

 Note: runtime-collected statistics and their names fall outside QEMU's usual
       deprecation policies.  QEMU will try to keep the set of available data
       stable, together with their names, but will not guarantee stability
       at all costs; the same is true of providers that source statistics
       externally, e.g. from Linux.  For example, if the same value is being
       tracked with different names on different architectures or by different
       providers, one of them might be renamed.  A statistic might go away if
       an algorithm is changed or some code is removed; changing a default
       might cause previously useful statistics to always report 0.  Such
       changes, however, are expected to be rare.

Since libvirt is not doing any form of conversion of the stats we can't
meaningfully document any of the returned fields. At the same time we
can't even meaningfully provide any form of API stability for the field
names.

Modify the documentation for the 'VIR_DOMAIN_STATS_VM' group both in the
API docs and in the virsh man page to reflect that and disclaim any form
of stability guarantees we provide normally.

f53988d657 docs: Do not support non-socket activated modular daemons with systemd
Due to the setup of the modular daemon service files the reverting to non-socket
activated daemons could have never worked.  The reason is that masking the
socket files prevents starting the daemons since they require (as in Requires=
rather than Wants= in the service file) the sockets.  On top of that it creates
issues with some libvirt-guests setups and needlessly increases our support
matrix.

Nothing prevents users to modify their setup in a way that will still work
without socket activation, but supporting such setup only creates burden on our
part.

This technically reverts most of commit 59d30adacd except the change made to
the libvirtd manpage since the monolithic daemon still supports traditional mode
of starting even on systemd.

83c6d80abc tools: add virt-qemu-qmp-proxy for proxying QMP via libvirt QEMU guests
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.

59d30adacd libvirt-guests: Fix dependency ordering in service file
After some debugging and discussion with systemd team it turns out we
are misusing the ordering in libvirt-guests.service.  That happened
because we want to support both monolithic and modular daemon setups and
on top of that we also want to support socket activation and services
without socket activation.  Unfortunately this is impossible to express
in the unit file because of how transactions are handled in systemd when
dependencies are resolved and multiple actions (jobs) are queued.  For
explanation from Michal Sekletar see comment #7 in the BZ this patch is
fixing:

https://bugzilla.redhat.com/show_bug.cgi?id=1964855#c7

In order to support all the scenarios this patch also amends the
manpages so that users that are changing the default can also read how
to correct the dependency ordering in libvirt-guests unit file.

Ideally we would also keep the existing configuration during upgrade,
but due to our huge support matrix this seems hardly feasible as it
could introduce even more problems.

8603b3d76c tools: add '--xpath EXPRESSION --wrap' args to all dumpxml commands
While you can chain the virsh output up to a later 'xmllint' or 'xpath'
command, integrating it into virsh avoids needs for installing extra
binaries which we've often found to be missing on production installs
of libvirt. It also gives better response if the initial virsh command
hits an error, as you don't get an aborted pipeline.

    $ virsh pool-dumpxml --xpath //permissions default
    <permissions>

      <group>1000</group>
      <label>unconfined_u:object_r:svirt_home_t:s0</label>
    </permissions>

If multiple nodes match, they are emitted individually:

    $ virsh dumpxml --xpath '//devices/*/address[@type="pci"]' --wrap demo
    <address type="pci" domain="0x0000" bus="0x05" slot="0x00" function="0x0"/>
    <address type="pci" domain="0x0000" bus="0x03" slot="0x00" function="0x0"/>

    <address type="pci" domain="0x0000" bus="0x07" slot="0x00" function="0x0"/>

but if intending to post-process the output further, the results
can be wrapped in a parent node

    $ virsh dumpxml --xpath '//devices/*/address[@type="pci"]' --wrap demo
    <nodes>
      <address type="pci" domain="0x0000" bus="0x05" slot="0x00" function="0x0"/>

98ffd82060 docs: Simplify passing of 'href_base' XSL variable
Historically we had two top level XSL files for top level and nested
documents which only differ in what they pass for 'href_base' to the
main 'page.xsl' file.

We can instead pass the variable as argument from the build system so
that we have just one XSL file and also allow for more nested document
trees in the future.

The '404' page is special even with the current XSL way so we add a
special case for it.

b94239a61e meson: Use dicts to initialize cfg_data objects
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.
