This role will install the following Systemd services:
* nova-server
* nova-compute

Tags
~~~~
This role supports two tags: ``nova-install`` and ``nova-config``
The ``nova-install`` tag can be used to install and upgrade.
The ``nova-config`` tag can be used to manage configuration.
CPU platform compatibility
~~~~~~~~~~~~~~~~~~~~~~~~~~
This role supports multiple CPU architecture types. At least one repo_build
node must exist for each CPU type that is in use in the deployment.
Currently supported CPU architectures:
- x86_64 / amd64
- ppc64le
At this time, ppc64le is only supported for the Compute node type. It can not
be used to manage the OpenStack-Ansible management nodes.
Compute driver compatibility
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This role supports multiple nova compute driver types. The following
compute drivers are supported:
- libvirt (default)
- ironic
- lxd (via nova-lxd)
- powervm (via nova-powervm)
The driver type is automatically detected by the OpenStack Ansible Nova role
for the following compute driver types:
- libvirt (kvm / qemu)
- powervm
Any mix and match of compute node types can be used for those platforms,
except for ironic.
If using the lxd driver, the compute type must be specified using the
``nova_virt_type`` variable.
The ``nova_virt_type`` may be set in
``/etc/openstack_deploy/user_variables.yml``, for example:
.. code-block:: shell-session
nova_virt_type: lxd
You can set ``nova_virt_type`` per host by using ``host_vars`` in
``/etc/openstack_deploy/openstack_user_config.yml``. For example:
.. code-block:: shell-session
compute_hosts:
aio1:
ip: 172.29.236.100
host_vars:
nova_virt_type: lxd
If ``nova_virt_type`` is set in ``/etc/openstack_deploy/user_variables.yml``,
all nodes in the deployment are set to that hypervisor type. Setting
``nova_virt_type`` in both ``/etc/openstack_deploy/user_variables.yml`` and
``/etc/openstack_deploy/openstack_user_config.yml`` will always result in the
value specified in ``/etc/openstack_deploy/user_variables.yml`` being set on
all hosts.
