In most cases, disabling the secure-boot or the enrolled-keys

It should be enough to enable or disable the enrolled-keys feature
to control whether Secure Boot is enforced, but there's a slight
complication: many distro packages for edk2 include, in addition
to general purpose firmware images, builds that are targeting the
Confidential Computing use case.
For those, the firmware descriptor will not advertise the
enrolled-keys feature, which will technically make them suitable
for satisfying a configuration such as
<os firmware='efi'>
<firmware>
<feature state='off' name='enrolled-keys'/>
</firmware>
</os>
In practice, users will expect the general purpose build to be
used in this case. Explicitly asking for the secure-boot feature
to be enabled achieves that result at the cost of some slight
additional verbosity.

Normally when an UEFI firmware is marked as read-only, an associated
NVRAM file will be created. Some builds of UEFI firmware, however, wish
to remain stateless and so will be read-only, but never have any NVRAM
file. To represent this concept a 'stateless' tristate bool attribute
is introduced on the <loader/> element.
There are rather a large number of permutations to consider.

While we all understand that excessive use of ternary operator
may worsen code readability (e.g. nested, multi-line expression),
there are few cases where using it actually improves code
readability. For instance, when a function takes a long list of
arguments out of which one depends on a boolean expression, or
when formatting "yes"/"no" or "on"/"off" values based on a
boolean variable (although one can argue that the latter is a
subset of the former). Just consider alternatives to:
virBufferAsprintf(buf, "<elem>%s</elem>\n", boolVar ? "yes" : "no");
In fact, this pattern occurs plenty in our code. Exempt it from
our "no ternary operators" rule.

Add the ability to configure a qemu-vdagent in guest domains. This
device is similar to the spice vdagent channel except that qemu handles
the spice-vdagent protocol messages itself rather than routing them over
a spice protocol channel.
The qemu-vdagent device has two notable configuration options which
determine whether qemu will handle particular vdagent features:
'clipboard' and 'mouse'.
The 'clipboard' option allows qemu to synchronize its internal clipboard
manager with the guest clipboard, which enables client<->guest clipboard
synchronization for non-spice guests such as vnc.
The 'mouse' option allows absolute mouse positioning to be sent over the
vdagent channel rather than using a usb or virtio tablet device.

<channel type='qemu-vdagent'>

Docutils-0.17 switched to using <main> instead of a <div
class='document'> and <section> instead of <div class='section'>.
To ensure that our pages still work we need to slightly adapt our XSL
stylesheet to select the <main> tag properly and adapt the CSS to also
select the 'section' element instead of a class and to apply to a <main>
tag with the appropriate names.
Docutils-0.17 also changed to use 'h2' for section heading instead of
'h1'.
Note the styles applied to the 'main' element with certain id can't be
made more universal by just applying to the id itself, as in certain
cases (e.g. 'documentation') we also have sections with that name. This
was previously ensured by also matching the 'document' class which would
make it equal to the 'main' element.

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.

Our last default template had a match of "node()" which incidentally matched

the XSLT spec, section 5.5:
https://www.w3.org/TR/1999/REC-xslt-19991116#conflict
this is an error. Also according to the same spec section, the XSLT processor
may signal the error or pick the last rule.
This was uncovered with libxslt 1.1.35 which contains the following commit:
b0074eeca3
which makes the build fail with:
runtime error: file ../docs/page.xsl line 223 element element
xsl:element: The effective name '' is not a valid QName.
because our last rule also matches text nodes and we are trying to extract the
node name out of them.
To fix this we change the match to "*" which only matches elements and not all
the nodes, and to avoid any possible errors with different XSLT processors we
also bump the priority of the match="text()" rule a little higher, just in case
someone needs to use an XSLT processor that chooses signalling the error instead
of the optional recovery.

Since we are at a transition period where some users may be running
monolithic libvirtd and others already the modular topology we need a
section that allows users to figure out which is in use.
This will be particularly important in the document about enabling
logging, as the active log file depends on which daemon is in use.

It's the only GIF file we have in our repository.
We could convert it to PNG, but that would result in a
significantly bigger file (~5.5 KiB vs ~1.5 KiB).

When invoking 'virsh guestinfo $VM' without explicitly specifying a
group of information to return, virsh always reports success even when
the guest agent doesn't report any information in the current state.
This is desired in situations when you are okay with stats being missing
and avoids spurious errors being reported.
Clarify that this is really desired in the man page.

Move out the settings required to pre libvirt-4.4.0 deployments into a
separate section so that the main point is not cluttered by now mostly
