rename included files to not have ".rst" extension, otherwise they are being scanned for ref targets and found targets are effectively counted twice (both in file that includes, and in the file being included), producing a warning/error.

Boot mode support
|
|
-----------------
|
|
|
|
Most of the bare metal drivers (including the generic ``ipmi`` hardware type)
|
|
support setting of boot mode (Legacy BIOS or UEFI). The boot modes can be
|
|
configured in the Bare Metal service in the following way:
|
|
|
|
* When no boot mode setting is provided, these drivers default the boot_mode
|
|
to Legacy BIOS.
|
|
|
|
* Only one boot mode (either ``uefi`` or ``bios``) can be configured for
|
|
the node.
|
|
|
|
* If the operator wants a node to boot always in ``uefi`` mode or ``bios``
|
|
mode, then they may use ``capabilities`` parameter within ``properties``
|
|
field of an bare metal node. The operator must manually set the appropriate
|
|
boot mode on the bare metal node.
|
|
|
|
To configure a node in ``uefi`` mode, then set ``capabilities`` as below::
|
|
|
|
openstack baremetal node set <node-uuid> --property capabilities='boot_mode:uefi'
|
|
|
|
Nodes having ``boot_mode`` set to ``uefi`` may be requested by adding an
|
|
``extra_spec`` to the Compute service flavor::
|
|
|
|
nova flavor-key ironic-test-3 set capabilities:boot_mode="uefi"
|
|
nova boot --flavor ironic-test-3 --image test-image instance-1
|
|
|
|
If ``capabilities`` is used in ``extra_spec`` as above, nova scheduler
|
|
(``ComputeCapabilitiesFilter``) will match only bare metal nodes which have
|
|
the ``boot_mode`` set appropriately in ``properties/capabilities``. It will
|
|
filter out rest of the nodes.
|
|
|
|
The above facility for matching in the Compute service can be used in
|
|
heterogeneous environments where there is a mix of ``uefi`` and ``bios``
|
|
machines, and operator wants to provide a choice to the user regarding
|
|
boot modes. If the flavor doesn't contain ``boot_mode`` and ``boot_mode``
|
|
is configured for bare metal nodes, then nova scheduler will consider all
|
|
nodes and user may get either ``bios`` or ``uefi`` machine.
