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.

libvirt doesn't really support the microvm machine type, but

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The files that are being replaced date back to RHEL 7 and no
longer represent what libvirt is likely to encounter on an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.

For historical reasons (i.e. unknown reason) we put channel
sockets into a path derived from cfg->libDir which is a path that
survives host reboots (e.g. /var/lib/libvirt/...). This is not
necessary and in fact for session daemon creates a longer prefix:
XDG_CONFIG_HOME -> /home/user/.config
XDG_RUNTIME_DIR -> /run/user/1000
Worse, if host is rebooted suddenly (e.g. due to power loss) then
we leave files behind and nobody will ever remove them.
Therefore, place the channel target dir into state dir.

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.

We've reached a point in lcitool where we can't steer its development
based solely on libvirt's needs IOW there will be times where a local
override of value (e.g. package mapping) will be necessary - an example
of this would be QEMU.
In case of this particular patch we need to add an override for the
cirrus FreeBSD 13 image we request in our CI to fix:
/usr/local/lib/libtasn1.so.6: Undefined symbol "strverscmp@FBSD_1.7"
The reason why we can't/should not make the fix in upstream lcitool
just yet is that we store a libosinfo ID in lcitool's OS target YAML
configs and at the time of writing this patch libosinfo does not have
a corresponding entry/ID for FreeBSD 13.2 so we have to stick with 13.1
in lcitool until they do so.
For the time being, the fix can easily be done on libvirt side as does
this patch.

It is quite confusing seeing these two in a call like this one:
$ meson build $MESON_OPTS $MESON_ARGS
One has to ask 'how are they different' and 'shouldn't these be
merged'. In fact, these variables hold very different things and we
should make it more obvious. The problem is that renaming MESON_OPTS to
something more meaningful, like 'MESON_CROSS_OPTS' which is what
MESON_OPTS really does would require changes to lcitool and would
impact Dockerfile generation which in turn might have an impact on
other projects which rely on this lcitool functionality which is risky.
Instead, provide a docstring for the former to supplement the latter
and join the two variables in a single one MESON_ARGS which is then
passed to meson's command line so it's a little less confusing.

When spawning a new container (via clone()) we allocate stack for

to glib. With glib we switched to g_strerror() which localizes
errno strings and thus increases stack usage, while the
previously used strerror_r() was more compact.
Fortunately, the solution is easy - just increase how much stack
the child can use (16 pages ought to be enough for anybody).
And while at it, lets use mmap() for allocation which offer some
nice features:
MAP_STACK - align allocation to be suitable for stack (even
though, currently ignored on Linux),
