<title>Manage bare metal nodes</title>
|

<para>The bare metal driver for OpenStack Compute manages
|
||||
provisioning of physical hardware using common cloud APIs and
|
||||
tools such as Orchestration (Heat). The use case for this driver
|
||||
is for single tenant clouds such as a high-performance computing
|
||||
cluster or deploying OpenStack itself. Development efforts are
|
||||
focused on moving the driver out of the Compute code base in the
|
||||
Icehouse release. If you use the bare metal driver, you must
|
||||
create and add a network interface to a bare metal node. Then, you
|
||||
can launch an instance from a bare metal image.</para>
|
||||
<para>You can list and delete bare metal nodes. When you delete a
|
||||
node, any associated network interfaces are removed. You can list
|
||||
and remove network interfaces that are associated with a bare
|
||||
metal node.</para>
