The "sclp" device is just an internal device that can not be instantiated by the users. If they try to use it, they only get a simple error message: $ qemu-system-s390x -nographic -device sclp qemu-system-s390x: Option '-device s390-sclp-event-facility' cannot be handled by this machine Since sclp_init() tries to create a TYPE_SCLP_EVENT_FACILITY which is a non-pluggable sysbus device, there is really no way that the "sclp" device can be used by the user, so let's set the user_creatable = false accordingly.
