Assigning to Deepti for review. Deepti - some more instance-related questions it might be a good candidate to tackle in the MII when you have a moment to take a look. Assigning Martin as the QA contact. This content is live on the Customer Portal. Closing. |
In RHEL-OSP, it is possible to create a snapshot of an instance from the dashboard and the CLI. For example - $ nova image-create <instance_id> <new_image_name> Or, clicking the 'Create Snapshot' option from the drop-down list for a virtual machine. This creates a new image that acts as a snapshot of the virtual machine, which allows you to create new instances based on that snapshot, and potentially restore an instance to that state. Moreover, this can be performed while the instance is running. What we likely need is the following - * Conceptual information on instance snapshots - What is an instance snapshot? - If I create an instance snapshot, which users and projects can access it by default? - Why would I want to create an image snapshot? - What happens if you delete the instance on which the snapshot is based? Running 'nova image-list' shows that the snapshot includes the ID of the server on which it was based. What is the connection? - Are snapshots differential, or are they a full image? * A procedure outlining how to create a snapshot in the dashboard. * A procedure outlining how to rebuild an instance that also includes a note that mentions that you can use an instance snapshot to restore an instance to the state in that snapshot.
