You can poll the Task managed object for its info.state. If it's done successfully, it is Enum success.

You are right the method is async call so you have to block your thread by yourself. If you use VI Java API, it's as simple as:

Task task = vm. shutdownGuest();

if(task.waitForme==Task.SUCCESS)

{...}

else

{...}

Hi,

According to VI SDK API reference vm.ShutdownGuest method just send shutdown command to guest operating system and returns immediately. It does not wait for the guest operating system to complete the operation.

The easiest way to check if operation is completed is to loop and wait vm.runtime.powerstate to change to poweredOff.

You can also check if guest has a pending shutdown command examining vm.guest.guestState == "shuttingdown"

Hi. The problem with that is vm.shutdownGuest() is of type void :

VMpowerOps.java:117: incompatible types

found : void

required: com.vmware.vim25.mo.Task

Task task = vm.shutdownGuest();
