Manage instances

As an administrative user, you can manage instances for users in various projects. You can view, terminate, edit, perform a soft or hard reboot, create a snapshot from, and migrate instances. You can also view the logs for instances or launch a VNC console for an instance.

For information about using the Dashboard to launch instances as an end user, see the launch-and-manage-instances.

Create instance snapshots

1. Log in to the Dashboard and select the admin project from the drop-down list.
2. On the Admin tab, open the Compute tab and click the Instances category.
3. Select an instance to create a snapshot from it. From the Actions drop-down list, select Create Snapshot.
4. In the Create Snapshot window, enter a name for the snapshot.
5. Click Create Snapshot. The Dashboard shows the instance snapshot in the Images category.
6. To launch an instance from the snapshot, select the snapshot and click Launch. For information about launching instances, see the launch-and-manage-instances.

Control the state of an instance
