From this link: http://docs.openstack.org/developer/n... , it can be seen that the state machine of VM states is flat-styled and highly-complex.

Is it better to convert this flat state machine to the HSM (Hierarchical State Machine)?

Pros: utilize HSM benefits such as grouping related states to a parent state for some common handling, having ENTRY and EXIT handling for each state and etc

Cons: can introduce potential errors due to the re-work.
