Public bug reported:
Description
===========
When using Flat/Raw image type in nova, and flavors with none-empty ephemerals,
instance fails to boot.
Steps to reproduce
==================
1. create flavor with non-empty ephemeral
2. Boot instance with flavor from step 1.
Expected result
===============
Instance become active
Actual result
=============
Instance moved to ERROR state
Environment
