<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>
