Hi all,<br>
<br>
I've added the bits about the db migration and the new data model to the<br>
wiki so please feel free to comment.<br>
<br>
I will follow up with the API data model and extenstions and how to make<br>
it backwards compatible - i.e. nova still working with the old<br>
--block-device-mapping boot parameters.<br>
<br>
Cheers,<br>
<br>
Nikola<br>
