Marios Andreou commented on DTACLOUD-209:
-----------------------------------------
update - I posted a question about the discrepancy between the HP cloud API
docs and the implementation:
https://community.hpcloud.com/question/723/server-status-api
> Instance States - Openstack provider - Instances go from RUNNING ->PENDING
> ->Not Existing. Should transition from RUNNING -> STOPPING -> STOPPED
> -------------------------------------------------------------------------------------------------------------------------------------------------

> ****************
> Note from Marios:
> Easy fix on deltacloud side - we need to be more fine grained in translating
> the state reported back from HP (right now, 'ACTIVE' becomes 'RUNNING' and
> everything else becomes 'PENDING' - so even when HP says 'DELETED', instead
> of reporting 'STOPPING' we say 'PENDING' and then the instance disappears...)
> ****************
> Note from Matt Wagner:
> (Openstack instance launched through Conductor) it seems like, when an
> instance is stopped, it immediately stops being reported, so Conductor marks
> it as 'vanished' because it never sees it in 'stopped' state before it
> disappears.
> Not sure how much of that is the state change issue noted in Deltacloud, vs.
> how much is the OpenStack API itself immediately withdrawing instances after
> they are stopped.
