``deprecated_features``
:since:`Since 11.0.0`, S390 guests may utilize the ``deprecated_features``
attribute to specify toggling of CPU model features that are flagged as
deprecated by the hypervisor. When this attribute is set to ``off``, the
active guest XML will reflect the respective features with the disable
policy. When this attribute is set to ``on``, the respective features will
be enabled.
``cache``
:since:`Since 3.3.0` the ``cache`` element describes the virtual CPU cache.
If the element is missing, the hypervisor will use a sensible default.
