It is not possible to convert glance images as it fails with error, NoSuchOptError: no such option conversion_plugin_options in group [DEFAULT].
Steps to reproduce:
Ensure 'image_conversion' plugin is enabled in glance-image-import.conf as shown below:
[image_import_opts]
image_import_plugins = ['image_conversion']
[image_conversion]
output_format = raw
Run below command to create image:
$ glance image-create-via-import --disk-format qcow2 --container-format bare --name cirros --import-method web-download --uri http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img
Expected result:
Image should be converted to raw format on the fly.
Actual result:
Conversion fails

To test this with devstack, use one of the following workaround:
Workaround:
Change ExecStart mentioned in /<email address hidden> unit file to
ExecStart = /usr/local/
or
Make changes in glance/cmd/api.py as mentioned in [1] and then changing ExecStart mentioned in /<email address hidden> unit file to
ExecStart = /usr/local/
NOTE:
After modifying <email address hidden> we need to relaod deamon using "sudo systemctl daemon-reload" command
