Hi all:

         Currently, you can set the "delete_on_termination" field to the rood disk when creating the server. You can delete the root disk when you delete the server. However, this configuration item cannot be updated, so here we propose a scheme that can modify the "delete_on_termination" configuration item, such as [1].

In addition, the data volume of the instance should be allowed to be set whether it can be deleted when it is deleted to clean up the environment and free up storage space, such as [2].

These are the more consistent and strongly added requirements from our various OpenStack users.

Thank you, looking forward to your reply.
