Subject: Create "image_conversion_dir" before creating temporary file
X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=c6d58672ed9666cbd9ad0d6454b064d8d05b43cc;p=openstack-build%2Fcinder-build.git

Create "image_conversion_dir" before creating temporary file

In file "image_utils.py", "create_temporary_file" method is
failing because, CONF.image_conversion_dir folder doesn't exist.

This patch solves the issue by creating image_conversion_dir
directory before calling "create_temporary_file" method.
