// wait until the vm is offline

	}
	// check every 5 seconds
	System.sleep(5000);
}

if (timedOut) {
	errorCode = "Timed out! Host '" + vm.name + "' is still not running after " + guestRebootTimeoutMinutes + " minutes!";
	throw errorCode;
}

dosen't work for me.

I thing you have to compare "value" with "value":

if (vm.guest.toolsStatus.value === VcVirtualMachineToolsStatus.toolsNotInstalled.value) { .... }

Also "_toolsXXXXX" is missing in my doc.
