Abstract: Methods, systems and computer readable media for efficient state change support for hierarchical data models in a virtualized system are described. In some implementations, the method can include determining a system status including a system-level bit masked word having a plurality of bits, each bit corresponding to a status of a different hierarchical level of the system, and receiving a change notification. The method can also include querying an entity at a lower hierarchy level if a cascaded state change is identified for that entity. The method can further include continuing to query one or more entities in successively lower hierarchy levels so long as a cascaded state change is identified for a corresponding entity in a lower hierarchy level. The method can also include determining the current status for one or more entities having a changed status. Identifying a cascaded state change can include performing a logical exclusive OR operation on a previous status bit masked word and a current status bit masked word of an entity.

Abstract translation: 描述了用于虚拟化系统中的分级数据模型的有效状态改变支持的方法，系统和计算机可读介质。 在一些实现中，该方法可以包括确定包括具有多个位的系统级位掩码字的系统状态，每个位对应于系统的不同层级的状态，以及接收改变通知。 如果为该实体识别级联状态改变，该方法还可以包括查询较低层次级别的实体。 该方法可以进一步包括继续查询连续较低层次级别中的一个或多个实体，只要为较低级别级别的相应实体识别级联状态改变即可。 该方法还可以包括确定具有改变的状态的一个或多个实体的当前状态。 识别级联状态改变可以包括对先前状态位屏蔽字和实体的当前状态位屏蔽字进行逻辑异或运算。
