Manage bare-metal nodes

The bare-metal driver for OpenStack Compute manages provisioning of physical hardware by using common cloud APIs and tools such as Orchestration (Heat). The use case for this driver is for single project clouds such as a high-performance computing cluster, or for deploying OpenStack itself.

If you use the bare-metal driver, you must create a network interface and add it to a bare-metal node. Then, you can launch an instance from a bare-metal image.

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.

Commands

The following commands can be used to manage bare-metal nodes.

baremetal-interface-add

Adds a network interface to a bare-metal node.

baremetal-interface-list

Lists network interfaces associated with a bare-metal node.

baremetal-interface-remove

Removes a network interface from a bare-metal node.

baremetal-node-create

Creates a bare-metal node.

baremetal-node-delete

Removes a bare-metal node and any associated interfaces.

baremetal-node-list

Lists available bare-metal nodes.

baremetal-node-show

Shows information about a bare-metal node.

Create a bare-metal node

When you create a bare-metal node, your PM address, user name, and password should match the information in your hardware's BIOS/IPMI configuration.

$ nova baremetal-node-create --pm_address PM_ADDRESS --pm_user PM_USERNAME \
  --pm_password PM_PASSWORD $(hostname -f) 1 512 10 aa:bb:cc:dd:ee:ff

The following example shows the command and results from creating a node with the PM address 1.2.3.4, the PM user name ipmi, and password ipmi.

$ nova baremetal-node-create --pm_address 1.2.3.4 --pm_user ipmi \
  --pm_password ipmi $(hostname -f) 1 512 10 aa:bb:cc:dd:ee:ff
+------------------+-------------------+

| pm_user          | ipmi              |
| terminal_port    | None              |
+------------------+-------------------+

Add a network interface to the node

For each NIC on the node, you must create an interface, specifying the interface's MAC address.

$ nova baremetal-interface-add 1 aa:bb:cc:dd:ee:ff
+-------------+-------------------+
| Property    | Value             |
+-------------+-------------------+
| datapath_id | 0                 |
| id          | 1                 |
| port_no     | 0                 |
| address     | aa:bb:cc:dd:ee:ff |
+-------------+-------------------+

Launch an instance from a bare-metal image

A bare-metal instance is an instance created directly on a physical machine, without any virtualization layer running underneath it. Nova retains power control via IPMI. In some situations, Nova may retain network control via Neutron and OpenFlow.

$ nova boot --image my-baremetal-image --flavor my-baremetal-flavor test
+-----------------------------+--------------------------------------+
| Property                    | Value                                |
+-----------------------------+--------------------------------------+
| status                      | BUILD                                |
| id                          | cc302a8f-cd81-484b-89a8-b75eb3911b1b |
+-----------------------------+--------------------------------------+

... wait for instance to become active ...

Note

Set the --availability_zone parameter to specify which zone or node to use to start the server. Separate the zone from the host name with a comma. For example:

$ nova boot --availability_zone zone:HOST,NODE

host is optional for the --availability_zone parameter. You can simply specify zone:,node, still including the comma.

List bare-metal nodes and interfaces

Use the nova baremetal-node-list command to view all bare-metal nodes and interfaces. When a node is in use, its status includes the UUID of the instance that runs on it:

$ nova baremetal-node-list
+----+--------+------+-----------+---------+-------------------+------+------------+-------------+-------------+---------------+
| ID | Host   | CPUs | Memory_MB | Disk_GB | MAC Address       | VLAN | PM Address | PM Username | PM Password | Terminal Port |
+----+--------+------+-----------+---------+-------------------+------+------------+-------------+-------------+---------------+
| 1  | ubuntu | 1    | 512       | 10      | aa:bb:cc:dd:ee:ff | None | 1.2.3.4    | ipmi        |             | None          |
+----+--------+------+-----------+---------+-------------------+------+------------+-------------+-------------+---------------+

Show details for a bare-metal node

Use the nova baremetal-node-show command to view the details for a bare-metal node:

$ nova baremetal-node-show 1
