At client side the only way to know an instance action is doable is to making sure the status is a permanent status like ACTIVE or SHUTOFF and no action in progress, so the task-state is None.

In the above linked case tempest stopped the instance and the instance reached the "SHUTOFF/None".
'State transition "ACTIVE/powering-off" ==> "SHUTOFF/None" after 10 second wait'

Cool, at this time we can start the instance right ? No, other attribute needs to be checked.

The start attempt was rewarded with 409 :
 u'Instance 7bc9de3b-1960-476f-b964-2ab2da986ec7 in task_state powering-off. Cannot start while the instance is in this state

The below line indicates the task state, silently moved back to "SHUTOFF/powering-off" , before the 'start' attempt.

Please do not set the 'None' task-state when the 'powering-off' is not finished.
