Are you aware that Jansson can't parse all JSON generated by qemu, and
that the developers of Jansson did not seem sympathetic to patches that
would make it possible?  Libvirt recently reverted their use of Jansson
because of its inability to deal with unsigned 64-bit numbers (and
sadly, RFC7159 does not define bounds for what forms valid JSON numbers,
but merely leaves it up to implementations to decide for themselves).
