Hello folks,

I was looking into the provisioning process in OpenStack. If
force_raw_images flag is set to False, the provisioning process looks like:

(1) Copy the image
(2) Create a copy of the copied image to an appropriate flavor name
(3) Start the VM

while if it is set to True, the provisioning process looks like:

(1) Copy the image
(2) Convert image to raw
(3) Create a copy of the converted raw image to an appropriate flavor name
(4) Start the VM

For the former, copying the image to a flavor name is a redundant process.
Can that be eliminated? Any thoughts?

Provisioning images from very large images (>20G) necessitate investigating
all aspects of provisioning process. The reason one can have very large
images is due to VM snapshotting or software bundling etc.

Thanks.
