    defaultConfigOption (`bool`_):

       Indicates whether the associated set of virtual machine configuration options is the default one for a given host or cluster. Latest version is marked as default unless other version is specified via `defaultHardwareVersionKey`_ or `defaultHardwareVersionKey`_ . If this setting is TRUE, virtual machine creates will use the associated set of configuration options, unless a config version is explicitly specified in the `ConfigSpec`_ .
    runSupported (`bool`_):

       Indicates whether the associated set of configuration options can be used to power on a virtual machine on a given host or cluster.
