[openstack-dev] [Nova] Migration state machine proposal.

Question on some things seen in the below paste.
What is with 'finished' -> 'reverted' and 'finished' -> 'confirmed'?
Why does it jump over 'reverting' or 'confirming'? Should it?
The other question is the difference between 'failed' and 'error' in the
first diagram, any idea on why/how these are semantically different? The
difference between 'done' and 'finished' are also in my mind
Overall I'm very much inclined to have three state machines (one for
each type), vs the mix-mash of all three into one state machine (which
causes the confusion around states in the first diagram in that paste).
