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 <http://docs.openstack.org/user-guide/dashboard_launch_instances.html>`__.

Create instance snapshots
~~~~~~~~~~~~~~~~~~~~~~~~~

#. Log in to the Dashboard and choose the admin project from the
   drop-down list at the top of the page.

#. On the :guilabel:`Admin` tab, open the :guilabel:`System` tab
   and click the :guilabel:`Instances` category.

#. Select an instance to create a snapshot from it. From the
   :guilabel:`Actions` drop-down list, select :guilabel:`Create Snapshot`.

#. In the :guilabel:`Create Snapshot` window, enter a name for the snapshot.

#. Click :guilabel:`Create Snapshot`. The Dashboard shows the instance snapshot
   in the :guilabel:`Images` category.

#. To launch an instance from the snapshot, select the snapshot and
   click :guilabel:`Launch Instance`. For information about launching
   instances, see the
   `OpenStack End User Guide <http://docs.openstack.org/user-guide/dashboard_launch_instances.html>`__.

Control the state of an instance
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

#. Log in to the Dashboard and choose the admin project from the
   drop-down list at the top of the page.

#. On the :guilabel:`Admin` tab, open the :guilabel:`System` tab
   and click the :guilabel:`Instances` category.

#. Select the instance for which you want to change the state.

#. In the :guilabel:`More` drop-down list in the :guilabel:`Actions` column,
   select the state.

   Depending on the current state of the instance, you can choose to
   pause, un-pause, suspend, resume, soft or hard reboot, or terminate
   an instance (items in red are dangerous).

You can track costs per month by showing meters like number of VCPUs,

   PROJECT drop-down list.

#. On the :guilabel:`Admin` tab, click the :guilabel:`Instances` category.
