Public bug reported:
A recent change in the Folsom code has resulted in issues building new
instances with a non-zero root disk size. It is currently trying to
compare the flavor size to the size of the base image before the base
image is actually pulled down. As a result, builds fail with the
following error in nova-compute.log:

Here is the commit where the bug was introduced:
https://github.com/openstack/nova/commit/6740c4141ea1152529b82cbf6e5b808eaba912e7
It appears to be a merge issue with Folsom, as the prepare_template line
appears above the conditional in Grizzly.
