// set CPU and network throttling if needed
//
void set_throttles(APP_INIT_DATA& aid, VBOX_VM& vm) {
    double x = 0, y = 0;

    // VirtualBox freaks out if the CPU Usage value is too low to actually
    // do any processing.  It probably wouldn't be so bad if the RDP interface
    // didn't also get hosed by it.
    //
    x = aid.global_prefs.cpu_usage_limit;
    // 0 means "no limit"
    //
    if (x == 0.0) x = 100;
    // For now set the minimum CPU Usage value to 1.
    //
    if (x < 1) x = 1;
    vm.set_cpu_usage((int)x);

    // vbox doesn't distinguish up and down bandwidth; use the min of the prefs
    //
    x = aid.global_prefs.max_bytes_sec_up;
    y = aid.global_prefs.max_bytes_sec_down;
    if (y) {

        vm.set_network_usage(((int)x*8/1000));
