Good idea! May I call vm_stop() in a tcg helper? Like in the following 
example:

void helper_vm_stop(uint32_t msg_id)
{
    if (qemu_log_enabled()) {
        qemu_log("VM stopped: %s", err_msg_str[msg_id]);
    } else {
        fprintf(stderr, "VM stopped: %s", err_msg_str[msg_id]);
    }
#ifndef CONFIG_USER_ONLY
    vm_stop(0);
#endif
    env->exception_index = EXCP_HALTED;
    cpu_loop_exit();
}

If not, what is the proper way to stop/pause the VM from within the executed 
code?
