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

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.
Sample configuration:
<channel type='qemu-vdagent'>
<target type='virtio' name='com.redhat.spice.0'/>
<source>
<clipboard copypaste='yes'/>
<mouse mode='client'/>
</source>
</channel>
