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

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 will automatically be detected by the OpenStack Ansible Nova role for the following compute driver types: - libvirt - ironic - powervm

Any mix and match of compute node types can be used for those platforms.

If using the lxd driver, the compute type must be specified using the nova_virt_type variable in the /etc/openstack_deploy/user_variables.yml file.

nova_virt_type: lxd

It should be noted that if the nova_virt_type variable is set, then all nodes in the deployment will be set to that hypervisor type. It is recommended to allow the automatic hypervisor detection.
