Operations that change the power state of a vApp or any of its VMs can have different results when initiated from the vCloud API than they do when initiated from the vCloud Director Web Console.

As seen in the vCloud Director Web Console, a vApp can be Stopped, Running, or Partially Running. A VM can have any of the following states:
