Open Stack

Razique,

We have used it to hold the meta data (/var/lib/nova/instances) and boot
from volume for everything else. Since Denis was looking for cinder volume
support, he isn't far from just doing boot from volume anyways to
consolidate the storage layers. At least that was the transition we made
when trying to figure this out as well.

Regards,

jason
