~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The Compute service needs to be configured to use the Bare Metal service's
driver. The configuration file for the Compute service is typically located at
driver. The configuration file for the Compute service is typically located at
``/etc/nova/nova.conf``.
.. note::
This configuration file must be modified on the Compute service's
controller nodes and compute nodes.
As of the Newton release, it is possible to have multiple
nova-compute services running the ironic virtual driver (in
nova) to provide redundancy. Bare metal nodes are mapped to the
services via a hash ring. If a service goes down, the
available bare metal nodes are remapped to different services.
Once active, a node will stay mapped to the same nova-compute
even when it goes down. The node is unable to be managed through
the Compute API until the service responsible returns to an active
state.
The following configuration file must be modified on the Compute
service's controller nodes and compute nodes.
#. Change these configuration options in the ``default`` section, as follows:
