The STATE_MAP will be used by the V3 diagnostics support. Removing the underscore will indicate that the dictionary is no longer local. Change-Id: Ife13e179abf0c1b31dafdf19fb0f3b29054199f2

"""Power state is the state we get by calling virt driver on a particular

|
domain. The hypervisor is always considered the authority on the status
|
|
of a particular VM, and the power_state in the DB should be viewed as a
|
|
snapshot of the VMs's state in the (recent) past. It can be periodically
|
|
updated, and should also be updated at the end of a task if the task is
|
|
supposed to affect power_state.
