Seems like there is no register of your datastore in devstack.

You should try to follow the manual installation doc

Normally the default datastore are set, you can try this. Hope this will help you : )

I suggest you ask a new question rather than asking your question in an answer.

Well it looks something is wrong with your Cinder setup. See the Cinder tests at

You need the --datastore option. See

The message implies that it might be possible to configure a default datastore. I have not spent enough time to find out how to do that.
