Unregistering OS Templates
When you unregister an OS template, the template itself is not deleted from the nodes where it is installed.
To unregister a template:
- Make sure that no servers are based on the template you want to unregister. Templates used by any servers cannot be unregistered.
- Go to Services > Cloud Infrastructure > OS Templates in the Cloud Infrastructure group.
- Select the checkbox next to the template, and click Unregister.
- In the dialog window that opens, click Yes to confirm your choice.
