禁止虚拟机时间同步的方法

Today is chinese Olympic day,everyone is very happy,but everyone must go to work for 8 hours.So after saying 'morning' to my colleague,I prepared to be hard working.

I prepared for testing my software in virtual system.The software is Veritas storage foundation ha 5,but I can't find the demo license.I have applied for the demo license,but  received noting by now.

How can I do?use the license which has expired,but I must disable the time synchronizing first.OK, the step is as below.All this steps have test in my virtual system.such as vmware 5 ,virtual pc 2007.

In vmware workstation 5
      open the vmware configuation (.VMX) file in a text editor,add and set the following option to false
      tools.syncTime = "false" 
      tools.synchronize.restore  = "false" 
      time.synchronize.resume.disk = "false" 
      time.synchronize.continue  = "false" 
      time.synchronize.shrink = "false" 

In virtual pc 2007
      Open the virtual pc 2007 configuartion (.VMC) file in a text editor(notepad),and find the code as below
      <integration>
                <microsoft>
      then add the following codes
                    <components>
                         <host_time_sync>
                              <enabled type="boolean">false</enabled>
                         </host_time_sync>
                    </components>
      save the configuration file.

Ok now,the virtual system is close or shutdown or reset ,the system time is not be synchornization with the host system os time.
