<para>The baremetal driver is a hypervisor driver for OpenStack Nova
|
|
Compute. Within the OpenStack framework, it has the same role as the
|
|
drivers for other hypervisors (libvirt, xen, etc), and yet it is
|
|
presently unique in that the hardware is not virtualized - there is no
|
|
hypervisor between the tenants and the physical hardware. It exposes
|
|
hardware via OpenStack's API, using pluggable sub-drivers to deliver
|
|
machine imaging (PXE) and power control (IPMI). With this, provisioning
|
|
and management of physical hardware is accomplished using common cloud
|
|
APIs and tools, such as Heat or salt-cloud. However, due to this unique
|
|
situation, using the baremetal driver requires some additional
|
|
preparation of its environment, the details of which are beyond the
|
|
scope of this guide. </para>

|
<note><para>
|
|
Some OpenStack Compute features are not implemented by
|
|
the baremetal hypervisor driver. See the <link

|
|
hypervisor support matrix</link> for details.

For the Baremetal driver to be loaded and function properly,
|
|
ensure that the following options are set in
|
|
<filename>/etc/nova/nova.conf</filename> on your <systemitem
|
|
class="service">nova-compute</systemitem> hosts.
|
|
<programlisting language="ini">[default]
|
|
compute_driver=nova.virt.baremetal.driver.BareMetalDriver
|

firewall_driver = nova.virt.firewall.NoopFirewallDriver

There are many configuration options specific to the
|
|
Baremetal driver. Also, some additional steps will be
|
|
required, such as building the baremetal deploy ramdisk. See
|
|
the <link

|
|
main wiki page</link> for details and implementation suggestions.
