Removed docker references (the driver has been removed from nova). Update confilcting pages including tables to use xrefs instead. Add a rpc_all section to handle conflicts in the training-guides. Closes-Bug: #1291138 Closes-Bug: #1292612 Change-Id: I67ad31c3913cae4c2e9e3d2ce41302717af5d839

<title>Baremetal driver</title>
|
|
<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 through the OpenStack APIs, using pluggable sub-drivers to deliver
|
|
machine imaging (PXE) and power control (IPMI). With this, provisioning
|
|
and management of physical hardware is accomplished by using common cloud
|
|
APIs and tools, such as the Orchestration module (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
|
|
xlink:href="http://wiki.openstack.org/HypervisorSupportMatrix">
|
|
hypervisor support matrix</link> for details.</para></note>
|
|
<para>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.</para>

<para>Many configuration options are specific to the
|
|
Baremetal driver. Also, some additional steps are
|
|
required, such as building the baremetal deploy ramdisk. See
|
|
the <link
