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 OpenStack End User Guide </user/launch-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 OpenStack End User Guide </user/launch-instances>.

Control the state of an
instance

  1. Log in to the Dashboard and select the admin project from the
    drop-down list.

    dangerous).
