From: Christian Brauner <brauner@kernel.org> Test the object-add/object-del QMP commands with the monitor-qmp object type. - Basic lifecycle: chardev-add -> object-add -> object-del -> chardev-remove - Error: object-add with nonexistent chardev - Error: second monitor on same chardev (chardev already in use) - Removal of CLI-created QMP monitor succeeds - Error: object-remove on HMP monitor - Re-add after remove: same id and chardev reusable after removal Signed-off-by: Christian Brauner (Amutable) <brauner@kernel.org> [DB: modified to use object-add/object-del, removing redundant scenarios already handled by object-add/del code] Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Tested-by: Peter Krempa <pkrempa@redhat.com> Signed-off-by: Daniel P.
