features:
  - You can now set the Libvirt CPU model and feature flags from the
    appropriate entry under the ``nova_virt_types`` dictionary variable
    (normally ``kvm``).
    ``nova_cpu_model`` is a string value that sets the CPU model; this
    value is ignored if you set any ``nova_cpu_mode`` other than
    ``custom``.
    ``nova_cpu_model_extra_flags`` is a list that allows you to specify
    extra CPU feature flags not normally passed through with
    ``host-model``, or the ``custom`` CPU model of your choice.
upgrade:
  - If your configuration previously set the ``libvirt/cpu_model``
    and/or ``libvirt/cpu_model_extra_flags`` variables in a
    ``nova_nova_conf_overrides`` dictionary, you should consider
    moving those to ``nova_cpu_model`` and
    ``nova_cpu_model_extra_flags`` in the appropriate entry (normally
    ``kvm``) in the ``nova_virt_types`` dictionary.
