The metadata display widget was developed as a common way to display additional metadata about images, volumes, and flavors in the launch instance workflow. This fix integrates the metadata widget into the source step for displaying the extra metadata.
To test, this requires some one time setup steps:
Ensure that you have metadata definitions loaded into your environment.
Go to Admin --> Metadata Definitions
If you have metadata definitions, ensure that at least some of them are public and associated with images. If they are not, edit the visibility inline and change them from protected to not protected. Protected definitions can not be edited. So change the protection first. This table requires a page refresh after changing the value of a row (angular anybody?).
Some good definitions to test with are Shutdown behavior and libvirt driver options. They generally should not prevent you from launching a VM.
In addition, the database and runtime environment definitions. If you don't have them, you can get them from the below locations and use the Admin --> Metadata Definitions --> Import button to add them.

https://github.com/openstack/glance/blob/master/etc/metadefs/software-runtimes.json
https://github.com/openstack/glance/blob/master/etc/metadefs/software-webservers.json
Once you have verified that you have some sample definitions loaded, you will need to add them to an image. Go to Admin --> Images. Choose an image and click the in-row action to Update Metadata. Select some properties from the above suggested list and add them to your image.
Once you have metadata added to an image, you may then go into launch instance and collapse / expand the details drawer to see the metadata definitions rendered correctly.
