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.
