So for VCPU I can successfully apply the task and it will shutdown the VM, reduce VCPU and power it fine.
For any VMem reduce tasks I'm getting "The operation is not supported by the object"
I was thinking VMturbo can simply do the same steps.
My immediate thought is that there may be a reservation that needs to be reduced first. Have you sorted the actions by show top? Otherwise this may be something that is worth opening a support ticket for.
