BTW, it has been 9 years since we enabled dlopen for the main drivers.

Initially it was tedious to use when running from non-installed git
build dir, but we fixed that in 2014 with virFileFindResource, so that
it "just works".

The only bug we ever hit was when we initially tried to modularize
even the non-daemon drivers, and it broke usage from language bindings.

Every platform we care about, including Windows, has dlopen() or
equivalent functionality.

So perhaps it is time to *drop* support for building without modules.

It will simplify our makefiles quite a bit to be able to assume everything
is always dlopen'd modules, and will slightly simplify the code, and most
importantly ensure a single codepath, so we know the behaviour is always
the same.

Regards,
Daniel
