Many images requires minimum 2,5,10 Gib as minimum disk size, the 1 used by m1.tiny is frequently not enough.
It might be increased to 10 or the original 0 should be restored.
This bug is about why I see 'message": "No valid host was found. ", "code": 500, "created": "2014-06-17T07:35:44Z"'
when "Flavor's disk is too small for requested image'" was raised on the n-cpu side.
It is confusing, 'No valid host was found' type of messages sounds like there is no n-cpu running, or all of them full.
