-----------------------------------------
Hi Kamil,
since Deltacloud is an abstraction API we 'map' the various VM power states
from each individual cloud provider to a set of power state abstractions. As
you note, these include 'RUNNING', 'PENDING', 'STOPPED' etc [1].
For those states that you list as unsupported - do you think we can map them to
the existing Deltacloud states? If so can you suggest a mapping (either here or
with a patch). For example, perhaps we could map 'RESIZE' and 'REBUILD' to
'PENDING'. For those that don't 'fit' into any of the current Deltacloud states
- can you suggest new states to cover those?
With respect to the OS-EXT-STS:task_state and OS-EXT-STS:vm_state - indeed we
don't consider those at all. However I did recently add the ability to grab
those values as part of a server description in the ruby-openstack rubygem
[2][3] - this is the gem that the Deltacloud OpenStack driver uses to 'talk' to
the OpenStack services. I'm not sure where/how to report this information
however - do you have any suggestions? I think perhaps adding a 'provider_ext'
attribute to the server model [4] which would be a hash (key=>value) to capture
this type of 'extra' information?
thanks, marios

> OpenStack defines multiple instance stauses. Only few of them are supported
> by DeltaCloud driver.
> Currently supported statuses are:
> * REBOOT, HARD_REBOOT => REBOOT
> * DELETED => STOPPED
> * BUILD => PENDING
> * ERROR => ERROR
> * ACTIVE => RUNNING
> Not supported statuses, but present in OpenStack spec, are:
> * PASSWORD
> * REBUILD
> * RESCUE
> * RESIZE
> * REVERT_RESIZE
> * SHUTOFF
> * SUSPENDED
> * UNKNOWN
> * VERIFY_RESIZE
> Additionally current OpenStack version includes RackSpace extensions
> (http://docs.rackspace.com/servers/api/v2/cs-gettingstarted/content/show_server.html)
> that provide additional info on instance state.
> * OS-EXT-STS:task_state
> * OS-EXT-STS:vm_state
