Public bug reported:
With currently vmware driver. the power_off will explicitly calls
PowerOffVM_Task.
In this case, If a virtual machine is writing to disk when it receives a
Power Off command, data corruption may occur.
Actually in SDK, there is another method
ShutdownGuest which will issues a command to the guest operating system asking
it to perform a clean shutdown of all services.
So it is suggest to use ShutdownGuest first and wait for some interval,
if the power state is still up, make a force shutdown.
