本申请基于申请号为202010582905.X、申请日为2020年06月23日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请实施例涉及虚拟机迁移技术领域，具体而言，涉及一种跨云平台的虚拟机迁移方法、装置、存储介质及电子装置。
背景技术
很多企业往往在各地都有自己的云平台数据中心，以提供云桌面给不同地区的员工使用。有时候往往会出现在A地办公，但是云桌面在B地云平台上。这就造成了用户无法就近使用云桌面，网络带宽可能存在瓶颈，无法提供优质的用户体验。
同时，当某个数据中心资源出现瓶颈时，需要进行资源调度，将虚拟机向资源富余的数据中心进行迁移。当前的迁移方案只能完成同一数据中心内的虚拟机整机迁移，如果要进行异地迁移，只能通过将虚拟机从A数据中心导出再导入到B数据中心云平台的方式。
许多教育机构在建设自己的云桌面，往往采用单个教室使用一个虚拟化平台一体机的部署方案，易于部署以及维护。上述的传统方案具有如下的缺陷：(1)数据中心内迁移无法完成异地迁移，只能调度云平台内各个资源池之间的资源分布；(2)导入导出需要从源数据中心导出虚拟机，再将导出的虚拟机磁盘镜像和配置文件导入到目的虚拟机，全程需要人工干预，操作复杂；(3)导入导出改变了虚拟机磁盘文件链结构，无法保持磁盘文件链结构的一致性。
鉴于此，就亟待提供一种能够便于进行跨云平台异地迁移，不对虚拟机本身磁盘文件链结构改动的容灾备份实施方案。

为了便于对本申请所提供的技术方案的理解，下面将结合具体场景的实施例进行详细阐述。
本申请一实施例提供一种针对跨云平台的虚拟机异地迁移方法。通过在异地数据中心创建不带磁盘实体的目的虚拟机，打通异地云平台间消息组件的消息通道，基于管理网的网络拷贝方式以完全对称的方式拷贝磁盘文件链，最终实现虚拟机跨云平台异地迁移，同时进行了对于磁盘共用节点不重复拷贝的设计，提升异地迁移的效率。
本申请一实施例提供一种在异地使用云桌面的场景下基于网络拷贝方式的虚拟机异地整机迁移的方法。首先，该方案能够实现虚拟机整机从A数据中心云平台迁移到B数据中心云平台。其次，该方案能够设置迁移的开始和结束时间，可以在非工作时间进行迁移避免影响用户的正常使用。再者，该方案迁移失败也不会对源虚拟机造成影响，用户依旧能够正常使用云桌面。另外，该方案保持了虚拟机磁盘文件链的结构，目的虚拟机和源虚拟机的磁盘结构一致。最后，该方案对于拷贝过的虚拟机共用文件节点不重复拷贝，提升了迁移效率。
本申请一实施例的核心内容就是通过打通不同云平台之间的消息组件，可以使管理平台互相通信获取虚拟机管理数据，基于网络拷贝方式完成虚拟机磁盘文件节点的逐以拷贝，拷贝过程完全对称化，确保了源虚拟机和目的 虚拟机的磁盘结构的一致性，同时对于共用的磁盘文件节点不进行重复拷贝，从而完成达到在极端有限条件下虚拟机的异地整机迁移。
图5是根据一些情况的通过导出导入方式将虚拟机迁移到异地云平台方案的示意图，如图5所示，通过导出导入虚拟机的操作，将虚拟机从A地云平台迁移到异地。即，首先，将A地虚拟机导出至nfs存储中；其次，通过导入操作将nfs存储上的磁盘镜像文件以及虚拟机的配置信息导入到B地云平台中。
图6是根据本申请一实施例的通过跨云平台迁移完成虚拟机整机迁移的示意图，如图6所示，首先，在B地云平台创建迁移的目的虚拟机，该虚拟机各种基本配置信息和源虚拟机保持一致，虚拟机不带磁盘实体文件，磁盘所在存储库为选择的B云平台中的存储库，虚拟机网卡配置为目的云平台中网络端口组；其次，按照磁盘文件链结构通过网络拷贝方式逐一迁移文件节点至B地云平台存储库中。
通过图5图6的的示意图对比，可以看到跨数据中心迁移的方案相对于导入导出方案的优势如下：第一，迁移过程完全自动化无须多次人为干预，操作流程方便；第二，保持了磁盘文件链结构，可以依旧保持文件节点的父子关系。
图7是根据本申请一些实施例的云平台内部整机迁移方案的示意图，图8是根据本申请一些实施例的云平台内部整机迁移方法的流程图，如图7和图8所示，该方法包括如下步骤：
步骤S801，构建虚拟机待迁移磁盘列表；
步骤S802，构建虚拟机每个磁盘待迁移文件列表；
步骤S803，针对每个磁盘文件节点选择平台内主机进行数据拷贝；
步骤S804，磁盘文件拷贝结束后虚拟机可运行于新的资源池以及新的存储库。
图9是根据本申请一实施例的云平台内部迁移以及跨平台迁移所依赖的组网条件的对比示意图，如图9所示，在同一平台内，存储库之间可以与主机都相通，那么直接通过存储网选择单台主机就可以完成磁盘数据的拷贝迁移。跨数据中心的虚拟机迁移，两地的存储网络是隔离的，因此依赖于管理网通过两个云平台中的两台主机相互配合完成磁盘文件节点的迁移。因此跨云平台可以在不依赖存储网，在极端条件下完成虚拟机的整机迁移。
通过图5与图6的导入导出跨平台迁移方案以及图9的平台内虚拟机迁 移和跨云平台的迁移对比。可以概括以下几点本方案的优势：
(1)操作流程完全自动化，只需要将需要迁移的虚拟机加入待迁移列表，同时设置好迁移的开始和结束时间，平台就能完成虚拟机的迁移操作；
(2)迁移不改变磁盘文件链的结构，从而能够保持差分特有的特性，比如虚拟机还原功能等；
(3)无须依赖存储网，在特定场景下就能完成虚拟机整机迁移。
下面结合附图对本实施例的技术方案的实施作进一步的详细描述：
本申请一实施例应用场景为大型数据中心虚拟化云平台环境中；
图10是根据本申请一实施例的跨云平台虚拟机异地迁移方法的流程图，如图10所示，该方法包括如下步骤：
S1001：通过管理界面将需要迁移的虚拟机加入迁移列表；
S1002：设置虚拟机迁移开始和结束的时间；
S1003：到达迁移时间后触发对于虚拟机的跨数据中心异地迁移操作；
S1004：发送消息至目的云平台创建目的虚拟机，目的虚拟机基本配置信息与源虚拟机一致。网卡端口组以及磁盘存储库使用目的云平台上的网络以及存储库；
S1005：构建待迁移的磁盘文件列表；
S1006：选择源云平台一个主机进行磁盘文件拷贝操作；
S1007：向选择的目的云平台发送消息，判断对端是否存在已经拷贝过的公用节点；
S1008：如果有共用节点正在拷贝，则等待拷贝完成；如果有共用节点已经拷贝完，则不需进行拷贝，进行下一文件节点拷贝；
S1009：如果是共用节点第一次拷贝，则向目的端主机发消息启动网络拷贝服务端；
S1010：源平台上的主机启动网络拷贝客户端；
S1011：完成文件节点拷贝，进行下磁盘文件节点的拷贝；
S1012：虚拟机磁盘均完成迁移，整机迁移结束。
本实施例可以针对大型的数据中心场景对业务虚拟机进行异地跨数据中心的整机迁移，通过打通消息组件单例模式，针对虚拟机磁盘进行完全对称化拷贝，基于网络拷贝方式完成虚拟机整机迁移。同时对于共用节点不进行重复拷贝，提升了迁移的效率。该方案能够完成方便完成虚拟机整机异地迁移，提升用户体验，降低运维成本，合理调度不通数据中心之间的资源。
通过本申请的上述实施例，由于通过在异地数据中心创建不带磁盘实体的目的虚拟机，打通异地云平台间消息组件的消息通道，基于管理网的网络拷贝方式以完全对称的方式拷贝磁盘文件链，因此，可以解决一些情况中数据中心内迁移无法完成异地迁移、导入导出全程需要人工干预、无法保持磁盘文件链结构的一致性的问题，达到实现虚拟机跨云平台异地迁移、保持磁盘文件链结构一致的效果。
