7d55c815c6 tools: load direct kernel config from libvirt
When connected to libvirt we can validate that the guest configuration
has the kernel hashes property enabled, otherwise including the kernel
GUID table in our expected measurements is not likely to match the
actual measurement.

When running locally we can also automatically detect the kernel/initrd
paths, along with the cmdline string from the XML.

0e911045ae tools: load guest config from libvirt
Accept information about a connection to libvirt and a guest on the
command line. Talk to libvirt to obtain the running guest state and
automatically detect as much configuration as possible.

It will refuse to use a libvirt connection that is thought to be local
to the current machine, as running this tool on the hypervisor itself is
not considered secure. This can be overridden using the --insecure flag.

When querying the guest, it will also analyse the XML configuration in
an attempt to detect any options that are liable to be mistakes. For
example the NVRAM being measured should not have a persistent varstore.

ececdbdfc0 tools: support validating SEV firmware boot measurements
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.

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.

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.

8e2a043c32 cmdQemuMonitorCommandQMPWrap: Reset ignored errors from JSON parsing
'cmdQemuMonitorCommandQMPWrap' is checking whether the user provided
string is not valid JSON to avoid wrapping it. In cases where it's not
JSON we ignore the error and add the wrapper.

If the caller then reports a different non-libvirt error the error from
the JSON parsing would be printed as well. Reset errors we ignore:

 # virsh qemu-monitor-command cd --pass-fds a asdf
 error: Unable to parse FD number 'a'
 error: internal error: cannot parse json asdf: lexical error: invalid char in json text.
                                        asdf
                      (right here) ------^

In the above case 'asdf' is not valid JSON, but the code did wrap it
into '{"execute":"asdf"}', the only problem is the argument for
--pass-fds.

e90d48ae6e virsh: Require --xpath for *dumpxml
Historically, the dumpxml command reject any unknown arguments,
for instance:

    virsh dumpxml fedora xxx

However, after v8.5.0-rc1~31 the second argument ('xxx') is
treated as an XPath, but it's not that clearly visible.
Therefore, require the --xpath switch, like this:

    virsh dumpxml fedora --xpath xxx

Yes, this breaks already released virsh, but I think we can argue
that the pool of users of this particular function is very small.
We also document the argument being mandatory:

   dumpxml [--inactive] [--security-info] [--update-cpu] [--migratable]
           [--xpath EXPRESSION] [--wrap] domain

The sooner we do this change, the better.

The same applies for other *dumpxml functions (net-dumpxml,
pool-dumpxml, vol-dumpxl to name a few).

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>
      <mode>0711</mode>
      <owner>1000</owner>
      <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"/>
    ...snip...
    <address type="pci" domain="0x0000" bus="0x00" slot="0x02" function="0x0" multifunction="on"/>
    <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"/>

used to find matching record in its config file. However, our NSS
module performs case sensitive comparison, which makes it useless
with ssh. Just consider a machine named FooBar.

Therefore, switch to case insensitive string comparison.

9223ebbc85 virsh: cmdBlockcopy: Fix generator of block copy disk XML
In a recent commit I've attempted to rewrite the XML generator to use
virXMLFormatElement instead of manual steps. Unfortunately the commit
had multiple problems resulting in a garbled XML:

1) in certain cases the wrong buffer was used resulting in misplaced
   snippets
2) the child element buffer was improperly set up so sub-elements were
   not indented

This resulted in following XML being generated:

 $ virsh blockcopy cd vda /tmp/test.copy --raw --print-xml
 type='file''/tmp/test.copy'/>
 <driver type='raw'/>
 <disk>
 <source file=</disk>

To fix this we'll generate the '<source>' element in one go and use the
proper buffer for it and other places.

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.

d5f81479a6 virsh: Fix integer overflow in allocpages
I've came across an aarch64 system which supports hugepages up to
16GiB of size. However, I was unable to allocate them using
virsh allocpages. This is because cmdAllocpages() uses
vshCommandOptScaledInt(), which scales passed value into bytes,
but since the virNodeAllocPages() expects size in KiB the
variable holding bytes is then divided by 1024. However, the
limit for the biggest value passed to vshCommandOptScaledInt() is
UINT_MAX which is now obviously wrong, as it needs to be UINT_MAX
* 1024.

The same bug is in completer. But here, let's use ULLONG_MAX so
that we don't have to care about it anymore.

c7dca225e5 virsh: cmdDesc: Fix logic when '-edit' is used along with 'desc' argument
Historically the use of the '-desc' multiple argument parameter was not
forbidden toghether with '-edit', but use of both together has some
unexpected behaviour. Specifically the editor is filled with the
contents passed via '-desc' but if the user doesn't change the text in
any way virsh will claim that the description was not chaged even if it
differs from the currently set description. Similarly, when the user
would edit the description provided via 'desc' so that it's identical
with the one configured for the domain, virsh would claim that it was
updated:

  # virsh desc cd
  No description for domain: cd
  # EDITOR=true virsh desc cd --edit "test desc"
  Domain description not changed

After the fix:

  # virsh desc cd
  No description for domain: cd
  # EDITOR=true virsh desc cd --edit "test desc"
  Domain description updated successfully
  # EDITOR=true virsh desc cd --edit "test desc"
  Domain description not changed

4e42686ade Make systemd unit ordering more robust
Since libvirt-guests script/service can operate on various URIs and we do
support both socket activation and traditional services, the ordering should be
specified for all the possible sockets and services.

Also remove the Wants= dependency since do not want to start any service.  We
cannot know which one libvirt-guests is configured, so we'd have to start all
the daemons which would break if unused colliding services are not
masked (libvirtd.service in the modular case and all the modular daemon service
units in the monolithic scenario).  Fortunately we can assume that the system is
configured properly to start services/sockets that are of interest to the user.
That also works with the setup described in https://libvirt.org/daemons.html .

To make it even more robust we add the daemon service into the machine units
created for individual domains as it was missing there.

d248e3dca8 virsh: domsetlaunchsecstate: report error if no options are passed
We already exit if they are not present.

Report an error, but do not mark them as required in case a future
version of this command will want to accept a different set of
parameters.

ec7fbdef56 virsh-network: Don't check for virshXXXTypeFromString() >= VIR_XXX_LAST
They way our VIR_ENUM_IMPL() and virXXXTypeFromString() work is
that for any string that's not recognized a negative one is
returned. And, since VIR_XXX_LAST is passed to VIR_ENUM_IMPL() we
can be sure that all enum members are covered. Therefore, there
is no way that virXXXTypeFromString() can return a value that's
bigger or equal to VIR_XXX_LAST.

I've noticed two places where such comparison was made, both in
cmdNetworkUpdate(). Drop them.

8eb4461645 remove sysconfig files
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.
