[Qemu-devel] [PATCH v3 13/17] monitor: Allow to exclude commands from QMP

[Jan Kiszka]

From: Jan Kiszka <jan.kis...@siemens.com>

Ported commands that are marked 'user_only' will not be considered for
QMP monitor sessions. This allows to implement new commands that do not
(yet) provide a sufficiently stable interface for QMP use (e.g.
device_show).
