The 'disk-cdrom-empty-network-invalid' is a special case were the input
XML is invalid according to the schema, but after processing a valid XML
is produced.
This corner case doesn't play well with 'virschematest' which uses the
file suffix to determine whether the file is invalid.
Upcoming patch will change the 'virschematest' condition, which would
start detecting this XML as invalid.
Use the '-active'/'-inactive' suffix for the file, which is possible
with qemuxml2xmltest so that an upcoming patch will not cause test

Due to the way the information is stored by the XML parser, we've
had this quirk where specifying any information about the loader
or NVRAM would implicitly set its format to raw. That is,
<nvram>/path/to/guest_VARS.fd</nvram>
would effectively be interpreted as
<nvram format='raw'>/path/to/guest_VARS.fd</nvram>
forcing the use of raw format firmware even when qcow2 format
would normally be preferred based on the ordering of firmware
descriptors. This behavior can be worked around in a number of
ways, but it's fairly unintuitive.
In order to remove this quirk, move the selection of the default
firmware format from the parser down to the individual drivers.
Most drivers only support raw firmware images, so they can
unconditionally set the format early and be done with it; the
QEMU driver, however, supports multiple formats and so in that
case we want this default to be applied as late as possible,
when we have already ruled out the possibility of using qcow2
formatted firmware images.

These are imported from Fedora 38's edk2 package.
The files that are being replaced date back to RHEL 7 and no
longer represent what libvirt is likely to encounter on an
actual production system.
Notably, the paths have all changed, with both x86_64 and
aarch64 builds now living under /usr/share/edk2 and the AAVMF
name being having been phased out.
Additionally, the 4MB qcow2 format builds have been introduced
on x86_64 and given high priority, effectively making qcow2
the default format across architectures.
The impact of these changes on the test suite is, predictably,
quite severe.
For the cases where paths to firmware files were explicitly
provided as part of the input, they have been adjusted so that
the modern paths are used instead of the legacy ones. Other
than that, input files have been left untouched.
The following expected changes can be seen in output files:
* where qcow2 firmware was used on x86_64, Secure Boot
support is now enabled;
* all ABI_UPDATE test cases for x86_64 now use qcow2
formatted firmware;
* test cases where legacy paths were manually provided
no longer get additional information about the firmware
added to the output XML.
Some of the changes described above highlight why, in order
to guarantee a stable guest ABI over time and regardless of
changes to the host's configuration, it was necessary to move
firmware selection from VM startup time to VM creation time.
In a few cases, updating the firmware descriptors changes the
behavior in a way that's undesired and uncovers latent bugs
in libvirt:
* firmware-manual-efi-secboot-legacy-paths ends up with
Secure Boot disabled, despite the input XML specifically
requesting it to be enabled;
* firmware-manual-efi-rw-modern-paths loses the
loader.readonly=no part of the configuration and starts
using an NVRAM file;
* firmware-manual-efi-nvram-template-nonstandard starts
failing altogether with a fairly obscure error message.
We're going to address all these issues with upcoming changes.

Most of these are just additional coverage, but a few demonstrate
bugs in libvirt:
* firmware-manual-efi-nvram-template-nonstandard sees the NVRAM
template path, which was explicitly provided in the XML,
being overridden by the firmware selection machinery;
* firmware-auto-efi-rw* and firmware-manual-efi-rw-legacy-paths
lose the loader.readonly=no setting and thus behave
differently than requested;
* firmware-manual-efi-loader-path-nonstandard fails because an
NVRAM path doesn't get generated.
We're going to address all these issues with upcoming changes.
Note that the firmware-auto-efi-nvram-template-nonstandard
failure is expected: firmware autoselection has been enabled, but
the NVRAM template points to a custom path that's not mentioned
in any of the firmware descriptors and so it can't succeed.

A <channel/> device is basically an UNIX socket into guest.
Whatever is sent from the host, appears in the guest and vice
versa. But because of that, the length of the path to the socket
is important (underscored by fact that we derive the path from
domain short name). But there are still cases where we might not
fit into UNIX_PATH_MAX limit (usually 108 characters), because
the path is derived also from other variables, e.g.
XDG_CONFIG_HOME for session domains.
There are two components though, that are needless: "/target/"
and "domain-" prefix. Drop them. This is safe to do, because
running domains have their path saved in status XML and even
though paths are dropped on migration, they are not part of guest
ABI and thus we are free to change them.

A test case can be part of a test suite (just like we already
have 'syntax-check'). This then allows developers to run only a
subset of tests. For instance - when using valgrind test setup
(`meson test -C _build/ --setup valgrind`) it makes zero sense to
run syntax-check tests or other script based tests (e.g.
check-augeas-*, check-remote_protocol, etc.). What does makes
sense is to run compiled binaries.
Strictly speaking, reaching that goal is as trivial as annotating
only those compiled tests (declared in tests/meson.build) and
running them selectively:
meson test -C _build/ --setup valgrind --suite $TAG
But it may be also desirable to run test scripts separately.
Therefore, introduce two new tags: 'bin' for compiled tests, and
'script' for script based tests and annotate each test()
accordingly.

Historically, the way to set PC speaker for a guest was to pass:

but as of QEMU commit v5.1.0-rc0~28^2~3 this is deprecated and we
should use:
-machine pcspk-audiodev=$id
instead. The old way was then removed in commit v7.1.0-rc0~99^2~3.
Now, ideally we would have a capability selecting whether we talk
to a QEMU that understands the new way or not. But it's not that
simple - the machine attribute is just an alias to the .audiodev=
attribute of 'isa-pcspk' object and both are created in
pc_machine_initfn() function, i.e. not then the PC_MACHINE() class
is initialized, but when it's instantiated. IOW, it's not possible
for us to query whether we're dealing with older or newer QEMU.
But given that the newer version is supported since v5.1.0 and the
minimal version we require is v4.2.0 (i.e. there are two releases
which don't understand the newer cmd line) and how frequently this
feature is (un-)used (the issue was reported after ~1 year since it

Both virtio-mem and virtio-pmem devices have '.memaddr' attribute
which controls the address where they are mapped in the guest
memory. Ideally, users do not need to specify this as QEMU does
the right thing and computes addresses automatically on startup.
But soon, we will need to record this address as it is part of
guest ABI. And also, there might be some users that want to
control this value. Now, we are in a bit of a pickle, because
both these device types already have a PCI address, therefore we
can't just use <address/> blindly. But what we can do, is
introduce <address/> under the <target/> element. This is also
more conceptual, as knobs under <target/> control guest visible
config of memory device (and .memaddr surely falls into that
category).
NB, SgxEPCDeviceInfo struct in QMP definition also has .memaddr
attribute, but because of the way we build cmd line there's no
(easy) way to set the attribute. So ignore that for now.

virpcimock (that the test uses) already creates a fake, but

When starting QEMU, or when hotplugging a PCI device QEMU might
lock some memory. How much? Well, that's an undecidable problem.
But despite that, we try to guess. And it more or less works,
until there's a counter example. This time, it's a guest with
both <hostdev/> and an NVMe <disk/>. I've started a simple guest
with 4GiB of memory:
# virsh dominfo fedora
Max memory: 4194304 KiB
Used memory: 4194304 KiB
And here are the amounts of memory that QEMU tried to lock,
obtained via:
grep VmLck /proc/$(pgrep qemu-kvm)/status
1) with just one <hostdev/>
VmLck: 4194308 kB
2) with just one NVMe <disk/>
VmLck: 4328544 kB
3) with one <hostdev/> and one NVMe <disk/>
VmLck: 8522852 kB
Now, what's surprising is case 2) where the locked memory exceeds
the VM memory. It almost resembles VDPA. Therefore, treat is as
such.
Unfortunately, I don't have a box with two or more spare NVMe-s
so I can't tell for sure. But setting limit too tight means QEMU
