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

The ``nova_virt_type`` may be set in
``/etc/openstack_deploy/user_variables.yml``, for example:
.. code-block:: shell-session .. code-block:: shell-session

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
