This capability detects the availability of the boot-bypass
property of the virtio-iommu-pci device.
This property was only introduced in QEMU 7.0 but, since the
device has been around for much longer, we end up querying its
properties for several more releases. As I don't have convenient
access to the 10+ binaries necessary to regenerate the replies,
I just put some fake data in there.

The prealloc-threads is property of memory-backend class which is

Therefore the property is present for all, or none if QEMU is
older than v5.0.0-rc0~75^2~1^2~3 which introduced the property.
Anyway, the .reserve property is the same story, and we chose

When -device is configured via JSON a bug [1] is triggered in qemu were
the DEVICE_DELETED event for the removal of the device frontend is no
longer delivered to libvirt. Without the DEVICE_DELETED event we don't
remove the corresponding entries in the VM XML.
Until qemu will be fixed we must stop using the JSON syntax for -device.
This patch removes the detection of the capability. The capability is
used only during startup of a fresh VM so we don't need to consider any
compaitibility steps for existing VMs.
For users who wish to use 'libvirt-7.9' and 'libvirt-7.10' with
'qemu-6.2' there are two possible workarounds:
- filter out the 'device.json' qemu capability '/etc/libvirt/qemu.conf':
capability_filters = [ "device.json" ]
- filter out the 'device.json' qemu capability via qemu namespace XML:
<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
[...]
<qemu:capabilities>
<qemu:del capability='device.json'/>
</qemu:capabilities>
</domain>
We must never again use the same capability name as we are now
instructing users to filter it as a workaround so once qemu is fixed
we'll need to pick a new capability value for it.

predates 3.0.0 (specifically it's v2.12.0-1689-g518d23a) and as
such does not reflect any change that was made to QEMU after the
snapshot and before the official relase. One of such changes was
renaming 'exit-preconfig' command to 'x-exit-preconfig' (QEMU
commit v3.0.0-rc1~21^2~3). Ideally, we would just regenerate

commandline switch used to implement the libvirt switch that will
likely result in a new and different method of selecting hotplug
modes. Because the libvirt switch has not been in any official
releases of libvirt, we are still able to remove it completely, rather
than deprecating it.

Starting with QEMU-6.2 started accepting a JSON object as argument for
'-device' which will also become the only syntax considered stable by
qemu in the future.
Since libvirt was recently converted to generate the properties via JSON
to begin wit we can start using it on the commandline as well, by simply
enabling the QEMU_CAPS_DEVICE_JSON capability, which we do by probing
for the 'json-cli' feature flag of 'device_add'.
Normally a change which changes a commandline output should be happening
only after the impacted real-caps test files are forked in the version
preceding the change, but in this case it's not necessary as the logic
for generating the device properties stays identical and we just change
the output format (avoid conversion). Additionally we still have a lot
of tests validating the conversion to the old commandline options.

Very recently, in qemu version 6.1, the same global option was also

ICH9-LPC.acpi-pci-hotplug-with-bridge-support
This option turns on or off acpi based hotplug for cold plugged pcie
bridges like pcie root ports. This flag is also enabled by
