This test is intended to simulate the use of an OVMF firmware
image installed under a non-standard path. In order to make
such a configuration work, the user would have to provide
additional information.
Right now it doesn't matter, because the configuration is
rejected anyway, but the behavior is going to change slightly
in the future. Prepare by making the configuration more
complete and realistic.

With its version 16.0, the LLVM's linker turned on
--no-undefined-version by default [1]. This breaks how we detect
--version-script= detection, because at the compile time there's
no library built yet that we can use to make --version-script=
happy. Unfortunately, meson does not provide a way to detect this
either [2].
But there's not much sense in detecting the argument either. We
already special case some systems (windows, darwin) and do the
check for others, which are expected to support versioned
symbols, because of ELF. Worst case scenario - the error is
reported during compile time rather than configure time.

The virNumaNodeIsAvailable function is stubbed out when building
without libnuma, such that it just returns a constant value. When
CLang is optimizing, it does inter-procedural analysis across
function calls. When it sees that the call to virNumaNodeIsAvailable
returns a fixed constant, it elides the conditional check for errors
in the callers such as virNumaNodesetIsAvailable.
This is a valid optimization as the C standard declares that there
must only be one implementation of each function in a binary. This
is normally the case, but ELF allows for function overrides when
linking or at runtime with LD_PRELOAD, which is technically outside
the mandated C language behaviour.
So while CLang's optimization works fine at runtime, it breaks in our
test suite which aims to mock the virNumaNodeIsAvailable function so
that it has specific semantics regardless of whether libnuma is built
or not. The return value check optimization though means our mock
override won't have the right effect. The mock will be invoked, but
its return value is not used.
Potentially the same problem could be exhibited with GCC if certain
combinations of optimizations are enabled, though thus far we've
not seen it.
To be robust on both CLang and GCC we need to make it more explicit
that we want to be able to replace functions and thus optimization
of calls must be limited. Currently we rely on 'noinline' which
does successfully prevent inlining of the function, but it cannot
stop the eliding of checks based on the constant return value.
Thus we need a bigger hammer.
There are a couple of options to disable this optimization:
* Annotate a symbol as 'weak'. This is tells the compiler
that the symbol is intended to be overridable at linktime
or runtime, and thus it will avoid doing inter-procedural
analysis for optimizations. This was tried previously but
have to be reverted as it had unintended consequences
when linking .a files into our final .so, resulting in all
the weak symbol impls being lost. See commit
407a281a8e
* Annotate a symbol with 'noipa'. This tells the compiler
to avoid inter-procedural analysis for calls to just this
function. This would be ideal match for our scenario, but
unfortunately it is only implemented for GCC currently:
https://reviews.llvm.org/D101011
* The '-fsemantic-interposition' argument tells the optimizer
that any functions may be replaced with alternative
implementations that have different semantics. It thus
blocks any optimizations across function calls. This is
quite a harsh block on the optimizer, but it appears to be
the only one that is viable with CLang.
Out of those choices option (3) is the only viable option for
CLang. We don't want todo it for GCC though as it is such a
big hammer. Probably we should apply (2) for GCC, should we
experiance a problem in future.

When a thread-context object is specified on the cmd line, then
QEMU spawns a thread and sets its affinity to the list of NUMA
nodes specified in .node-affinity attribute. And this works just
fine, until the main QEMU thread itself is not restricted.
Because of v5.3.0-rc1~18 we restrict the main emulator thread
even before QEMU is executed and thus then it tries to set
affinity of a thread-context thread, it inevitably fails with:
Setting CPU affinity failed: Invalid argument
Now, we could lift the pinning temporarily, let QEMU spawn all
thread-context threads, and enforce pinning again, but that would
require some form of communication with QEMU (maybe -preconfig?).
But that would still be wrong, because it would circumvent
<emulatorpin/>.
Technically speaking, thread-context is an internal
implementation detail of QEMU, and if it weren't for it, the main
emulator thread would be doing the allocation. Therefore, we
should honor the pinning and prune the list of node so that
inaccessible ones are dropped.
