QEMU supports only 'raw' and 'telnet' in the
<protocol type='telnets'/>
element. Reject 'telnets' and 'tls'. TLS transport for qemu chardevs is
configured via "tls='yes'" attribute added to the "<source>" element
instead, so this prevents potential misconfig as the value would be
silently accepted.

Use the 'chardev-backends' test data as symlink to invoke the test case
again asserting QEMU_CAPS_CHARDEV_JSON which will make the commandline
generator use the JSON representation of the -chardev backend instead
allowing us to validate it agains the QMP schema.

While qemu doesn't yet support JSON args for chardev, we can at least
for test purposes of schema validation plumb it to the '-chardev'
command as it's easier to create test cases via XML than to write them
into code in 'qemuhotplugtest'.
Additionally once this becomes available and if e.g. the syntax is fixed
we'll be able to also catch the differences early.

pvpanic-pci is the only reasonable implementation of a panic
device for aarch64/virt guests. Right now we're asking users to
provide the model name manually, but we can be more helpful and
fill it in automatically instead.
With this change, the aarch64-panic-no-model test no longer
fails and so it's no longer useful to us. Instead, we can amend
the aarch64-virt-default-models test case to include panic
coverage, something that until now wasn't possible.

Introduce tests to verify that the 'ps2' feature is correctly parsed
when given either 'dirty' XML from a user or 'clean' canonical XML,
as produced by libvirt. This also tests the transformation from libvirt's
internal state to the aforementioned canonical form and to a QEMU
command line.
As a bonus, we also test some known bad configurations:
- When user explicitly adds ps2 bus inputs, but also explicitly disables
the 'ps2' feature.
- When user explicitly enables the 'vmport' feature, but also explicitly
disables the 'ps2' feature. This is not supported by QEMU and will
result in vmport device not being created without emitting any warning

The aim of pstore device is to provide a bit of NVRAM storage for
guest kernel to record oops/panic logs just before the it
crashes. Typical usage includes usage in combination with a
watchdog so that the logs can be inspected after the watchdog
rebooted the machine. While Linux kernel (and possibly Windows
too) support many backends, in QEMU there's just 'acpi-erst'
device so stick with that for now. The device must be attached to
a PCI bus and needs two additional values (well, corresponding
memory-backend-file needs them): size and path. Despite using
memory-backend-file this does NOT add any additional RAM to the
guest and thus I've decided to expose it as another device type
instead of memory model.

Sync with the edk2-20240524-4.fc39 package from Fedora.
The only notable change is that the inteltdx variant now declares
support for Secure Boot and is a ROM image instead of a stateless
pflash one.
The latter causes it to be considered eligible for the
configuration described by the firmware-auto-efi-rw test cases,
which now passes instead of failing.
Of course that doesn't make any sense, because a ROM image by
definition cannot be read/write. So this indicates the presence

The current hostdev parsing logic sets rawio or sgio even if the hostdev type
is not 'scsi'. The rawio field in virDomainHostdevSubsysSCSI overlaps with
wwpn field in virDomainHostdevSubsysSCSIVHost, consequently setting a bogus
pointer value such as 0x1 or 0x2 from virDomainHostdevSubsysSCSIVHost's
point of view. This leads to a segmentation fault when it attempts to free
wwpn.
While setting sgio does not appear to crash, it shares the same flawed logic
as setting rawio.
Instead, we ensure these are set only after the hostdev type check succeeds.
This patch also adds two test cases to exercise both scenarios.
