发现以前发的代码失效了，用了之后还会在装VMware Tools后同步时间
这段代码应该不新，但是可以在8.0.4里把时间同步禁止：
tools.syncTime = "0"
time.synchronize.continue = "0"
time.synchronize.restore = "0"
time.synchronize.resume.disk = "0"
time.synchronize.shrink = "0"
time.synchronize.tools.startup = "0"
time.synchronize.tools.enable = "0"
time.synchronize.resume.host = "0"
