Re: [Rdo-list] Creating nova instance without backing image

Is there any way to tell Nova to not use backing image for an instance?
I don't know the answer to that question...but since you're already
using Ceph, couldn't you simply put your instance storage on Ceph (or
some other remote/cluster filesystem) as well? This would still mean
that for "single use" images you're using twice the space, but it
would remove the space limitations of the local filesystem.
