I disagree. The reason is because glance-api does not know where nova
is. Nova does.

I continue to think that the best performance gains will come from
getting rid of glance-api entirely, putting the block-streaming bits
into a separate Python library, and having Nova and Cinder pull
image/volume bits directly from backend storage instead of going through
the glance middleman.

Best,
