- the virtual machine is not persisted to the network management, and the interface of the resource pool is called to obtain the virtual machine.
- the data of its related objects call the persistence layer, and persist this part of the virtual machine to the network management system.
- Step 6 Take the difference set between the set B and the set A.

久化入网管系统数据库。
可选地，将虚拟机数据加载到网管系统进行持久化的操作是以虚拟机为事务粒度，并且虚拟机间采用最大努力方式进行数据加载。
在本实例中，通过在监听到虚拟化控制器发送的虚拟机启用消息通知时，获取虚拟化控制器虚拟化控制器发送的虚拟机启用状态消息；然后解析该虚拟机启用状态消息得到需要加载的目标虚拟机标识；最后根据该目标虚拟机标识从预设的虚拟机资源池中查找获取与该目标虚拟机标识对应的虚拟机数据，并将该虚拟机数据加载到网管系统中进行持久化，这样，实现了虚拟化控制的虚拟机数据及时同步到网管系统中，从而网管系统中的虚拟机数据与虚拟化控制器中的虚拟机数据实时保持一致，为网管系统的其他功能模块或程序提供实时数据源，也使用户能够实时了解虚拟化控制器的虚拟机数据情况，便于对虚拟化控制器的监控。
参照图2，图2为本发明实施例另一种虚拟机数据加载方法的流程示意图。
在本发明实施例另一种虚拟机数据加载方法中，步骤S10之前还包括：

机ID相同的虚拟机数据删除。
参照图8，本发明实施例的虚拟机数据加载方法所依附的虚拟机数据加载装置包括资源池、监听器和加载器三个结构，
一)资源池
资源池是一个分层结构，该资源池包括：
数据生成层，设置为根据虚拟机模型以及虚拟控制器支持的最大容量，计算出每种类型的虚拟机的数量，生成虚拟机的数据；
数据解析层：设置为解析数据生成层生成的虚拟机数据，按照虚拟机的粒度组织数据结构；
数据加载层：设置为将数据解析层生成的数据结构加载到内存，加载完成发送消息到加载器；
资源池接口层：设置为提供虚拟机访问接口，包括虚拟机查询接口，虚拟机比对接口。
二)监听器
监听器是一个分层结构，该监听器包括：
消息监听层，设置为监听来自虚拟化控制器的虚拟机启用状态消息；
消息转发层：设置为解析收到的虚拟机启用状态消息，并转发到加载器；
监听器接口层：设置为提供向虚拟控制器查询全部启用状态的虚拟机接口。
三)加载器
加载器是一个分层结构，该加载器包括：
监听层：设置为监听来至监听器消息转发层转发的虚拟机启用状态消息；同时监听资源池的数据加载层发送的消息。
解析层：设置为解析监听层的消息，得出需要加载的虚拟机ID，并调用持久化层入数据库；
持久化层：设置为根据解析层的虚拟机ID，调用资源池接口层的外部接
口，获取虚拟机数据，生成数据库操作命令并执行。
外部接口层：设置为提供外部接口，用户手工调用接口，更新网管系统中的虚拟机数据。因为网管系统的数据由于备份恢复等原因，会导致网管系统中的虚拟机数据与虚拟化控制器中实际运行的虚拟机数据不一致。
此外，根据本发明实施例的虚拟机数据加载方法，将虚拟机数据加载方法分为四种情况分别叙述：
第一种情况、网管系统初始启动，构造资源池，加载资源池中状态为启用的虚拟机数据持久化到网管，步骤如下：
步骤1，资源池数据生成层根据虚拟机模型以及虚拟控制器支持的最大容量，计算出每种类型的虚拟机的数量以及每种虚拟机的数据；
步骤2，资源池数据解析层按照虚拟机的粒度解析上一步生成的数据；
步骤3，加载层把虚拟机数据加载到内存，内存结构如图9。内存中维护一个Map(数据库地图)，主键为虚拟机的VMID，值为虚拟机对象。虚拟机对象及其相关对象如图10所示，虚拟机对象中保存了对归属于这个虚拟机的相关对象的引用，这种方式可以快速定位出每个虚拟机相关的所有数据，便于在网管系统中增加虚拟机和删除虚拟机。数据在内存加载完成后发送资源池加载完成消息；
步骤4，加载器的监听层收到消息后，解析层通过资源池提供的接口访问资源池中的虚拟机，获取启用状态为开启的虚机，获取虚拟机及其相关对象的全部数据，调用持久层的接口，持久化虚拟机数据到网管；持久化层的操作要以虚拟机为事务粒度，采用最大努力方式。
第二种情况、网管系统运行中，并且与虚拟化控制器链路无异常的情况下虚拟机数据加载，步骤如下：
步骤1，监听器的消息监听层与虚拟化控制器有长连接链路，接收虚拟化控制器的虚拟机启用消息通知；
步骤2，监听器的消息监听层收到消息后，解析消息，获取虚拟机ID和启用状态，通过监听器的消息转发层转发
步骤3，加载器的监听层收到转发消息后，解析层解析出虚拟机ID和启
用状态。
步骤4，调用资源池的接口，获取该虚拟机机器相关对象的全部数据，调用持久层的接口，持久化虚拟机数据到网管。虚拟机的启用状态不同，持久化处理方式不同，如果为ON，为增加虚拟机，如果为OFF，为删除虚拟机，持久化层的操作要以虚拟机为事务粒度，采用最大努力方式。
第三种情况、网管系统与虚拟化控制器链路断开发到恢复期间，监听器收不到虚拟化控制器的虚拟机状态消息，导致不能及时更新网管系统内的虚拟机数据，在链路恢复后，要重新加载网管系统的虚拟机数据，参照图11，步骤如下：
步骤1，链路恢复后，加载器调用监听器的接口层接口，获取当前虚拟化控制器的所有启用状态的虚拟机。
步骤2，监听器的消息监听层收到虚拟化控制器返回的查询结果，经过数据转发层的解析后转发给加载器。
步骤3，加载器的监听层收到消息后，解析层解析出虚拟机ID列表(集合A)
步骤4，获取当前网管系统持久化的虚拟机ID列表(集合B)
步骤5，取集合A与集合B的差集，这部分虚机为虚拟化控制器在链路恢复前启用的虚机，还没有持久化到网管，调用资源池的接口，获取这部分虚拟机及其相关对象的数据，调用持久化层，将这部分虚拟机持久化到网管系统。
步骤6，取集合B与集合A的差集，这部分虚机为虚拟化控制器在链路恢复前关闭的虚机，还没有在网管系统删除，调用资源池的接口，获取这部分虚拟机及其相关对象的数据，调用持久化层，将这部分虚拟机从网管系统删除；持久化层的操作要以虚拟机为事务粒度，采用最大努力方式。
第四种情况、资源池计算虚拟机数据的算法变化，会导致网管系统持久化的虚拟机数据与资源池中的虚拟机数据不一致，这种情况发生概率小，采用用户手动发起的方式，步骤如下：
步骤1，在用户调用加载器的外部接口层接口，发起本操作时，清除网
管系统中持久化的虚拟机数据；
步骤2，加载器调用监听器的接口层接口，获取当前虚拟化控制器的所有启用状态的虚拟机；
步骤3监听器的消息监听层收到虚拟化控制器返回的查询结果，经过数据转发层的解析后转发给加载器；
步骤4，加载器的监听层收到消息后，解析层解析出虚拟机ID列表(集合A)；
步骤5，调用资源池的接口，获取集合A虚拟机及其相关对象的数据，调用持久化层，将这部分虚拟机持久化到网管系统；持久化层的操作要以虚拟机为事务粒度，采用最大努力方式。
此外，为实现上述目的，本发明实施例还提供一种虚拟机数据加载装置，参照图4，虚拟机数据加载装置包括：
