由于该主虚拟机中包括多个本地驱动，该多个本地驱动分别与硬件层中的多个硬件资源一一对应，该主虚拟机可以通过任一个本地驱动和该本地驱动对应的硬件资源进行通信，因此，可以通过安装的产生该报警事件的资源的本地 驱动接收该硬件层中的报警监控器发送的第一报警信息，降低了对开发该主虚拟机的难度，且由于该本地驱动是与产生该报警事件的资源对应的本地驱动，因此，该主虚拟机机可以通过该本地驱动，快速准确地接收到产生该报警事件的资源的第一报警信息，即提高了接收第一报警信息的效率，从而提高了网络功能虚拟化环境中的报警效率。

其中，当该主虚拟机通过第一BSAD接收该报警信息、确定该至少一个目 标虚拟机标识并将该报警信息发送给该至少一个目标虚拟机时，能够减小该主虚拟机的复杂度，同时由于第一BSAD不需要和其它设备进行交互，因此也提升了该主虚拟机从接收该报警信息到将该报警信息发送给该至少一个目标虚拟机的效率，进而提高了该报警方法的效率。
需要说明的是，当该主虚拟机不是通过第一BSAD接收该报警信息时，该主虚拟机也可以通过第一BSAD基于该报警信息中携带的产生该报警事件的资源标识，确定该至少一个目标虚拟机标识。

图2A是本发明实施例提供的一种网络功能虚拟化环境中的报警方法的流程图，参见图2A，该报警方法用于NFV系统中，该报警方法包括：
步骤201：当该NFV系统包括的NFVI中的报警监控器检测到报警事件时，生成报警信息，并将该报警信息发送给主虚拟机，该报警信息中携带产生该报警事件的资源标识。
由于该NFV系统在运行时，该NFV系统中的NFVI可能会出现故障，从而影响该NFV系统的稳定性，因此，该NFVI中可以设置报警监控器，以对该NFVI中是否产生报警事件进行检测，当检测到该NFVI中有报警事件产生时，可以生成报警信息，该报警信息中携带产生该报警事件的资源标识，且为了对该报警事件进行处理，该NFVI中的报警监控器可以将该报警信息发送给该主虚拟机。
其中，该NFVI包括硬件层、虚拟层和软件层。
需要说明的是，该硬件层中包括物理计算资源、物理存储资源、物理网络资源等硬件资源，该物理计算资源可以是物理CPU(Central Processing Unit，中央处理器)、该物理存储资源可以是物理存储器，该物理网络资源可以是物理网络设备，当然，在实际应用中，该硬件层还可以包括其它硬件资源，且该物理计算资源、该物理存储资源和该物理网络资源分别还可以包括其它物理设备，本发明实施例对此不做具体限定。

其中，该主虚拟机可以是在通用的硬件平台上，基于XEN建立该NFV系统时得到，该主虚拟机可以用于建立用户虚拟机，并对用户虚拟机进行管理；用户虚拟机又被称为客户虚拟机，用户虚拟机可以是通过该主虚拟机进行安装得到，且能够安装并运行用户提供的应用程序。
需要说明的是，该虚拟层中可以包括一个用户虚拟机，也可以包括多个用户虚拟机，本发明实施例对此不做具体限定。
还需要说明的是，该软件层可以包括该主虚拟机的操作系统和用户虚拟机的操作系统。
其中，如图2B所示，该NFV系统包括的NFVI1中的硬件层11包括多个报警监控器，且每个报警监控器可以分别对应一个硬件资源，以对该硬件资源是否有报警事件产生进行检测。该NFVI1中的虚拟层12包括一个报警监控器，该虚拟层中的报警监控器可以对该虚拟层中的虚拟资源和该虚拟层中包括的多个用户虚拟机是否有报警事件产生进行检测。
需要说明的是，该硬件层中的报警监控器可以由硬件层中每个硬件资源的生产商在生产该硬件资源时设置得到，当然，在实际应用中，该硬件层中的报警监控器还可以在其它时机通过其它方式设置得到，本发明实施例对此不做具体限定。
还需要说明的是，该虚拟层中的报警监控器可以是在该硬件平台中基于XEN建立该NFV系统时得到，当然，在实际应用中，该虚拟层中的报警监控器还可以在其它时机通过其它方式设置得到，本发明实施例对此不做具体限定。
进一步地，对于该虚拟层12，在另一种可能的情况中，如图2C所示，该虚拟层12包括多个报警监控器，该多个报警监控器可以分别与该虚拟层中的虚拟资源一一对应。
还需要说明的是，该虚拟层的报警监控器还可以对主虚拟机和多个用户虚拟机是否有报警事件产生进行检测。
另外，该虚拟层中的报警监控器也可以对该软件层中包括的用户虚拟机的操作系统是否产生报警事件进行检测；或者，在另一种可能的实现方式中，该软件层也可以包括报警监控器，进而对该软件层中包括的用户虚拟机的操作系统是否产生报警事件进行检测。
需要说明的是，当该软件层也可以包括报警监控器时，该软件层中的报警监控器可以在通过该主虚拟机在该NFV系统中安装用户虚拟机时得到，当然，在实际应用中，该软件层中的报警监控器还可以通过其它方式设置得到，本发明实施例对此不做具体限定。
其中，该报警事件可以是该硬件层、该虚拟层或该软件层中产生的任一个报警事件，比如，对于该硬件层，该报警事件可以是物理CPU占用率过高、 物理存储空间不足、网络连接失败等；对于该虚拟层，该报警事件可以是虚拟CPU占用率过高、虚拟存储空间不足、网络连接失败、该主虚拟机宕机或某个用户虚拟机宕机等；对于该软件层，该报警事件可以是某个用户虚拟机的操作系统出现故障等。当然，在实际应用中，该报警事件还可以包括其它报警事件，本发明实施例对此不做具体限定。
其中，该报警信息中携带的资源标识为产生该报警事件的资源标识，该资源标识可以由该NFV系统在该NFVI中的报警监控器将生成报警信息之前确定。
进一步地，该报警信息中还可以携带其它信息，比如，报警信息标识、和报警事件说明和报警时间等信息，本发明实施例对此不做具体限定。
其中，该报警信息标识可以是该NFV中该报警事件的编号等，当然，在实际应用中，该报警信息标识还可以是其它能够标识该报警事件的信息，本发明对此不做具体限定。
例如，该NFVI中的报警监控器检测到报警事件1，且产生该报警事件的资源为物理CPU，物理CPU的资源标识为hardware01，报警事件说明为物理CPU占用率过高，因此，该NFVI的报警监控器生成报警信息1，该报警信息1中产生报警事件1的资源标识hardware01和报警事件说明物理CPU占用率过高，并将该报警信息1发送给该主虚拟机。
进一步地，该报警信息包括第一报警信息和第二报警信息，该第一报警信息为该硬件层中的报警信息，该第二报警信息为该虚拟层或该软件层中的报警信息。
需要说明的是，第一报警信息可以是该NFVI中的报警监控器检测到该硬件层的任一硬件资源有报警事件产生时生成的的报警信息，第二报警信息可以是该NFVI中的报警监控器检测到该虚拟层的任一虚拟资源、主虚拟机、多个多个用户虚拟机中的任一个用户虚拟机或者软件层有报警事件产生时生成的报警信息。
步骤202：该主虚拟机接收该NFVI中的报警监控器发送的报警信息。
由前述可知，该NFVI中的报警监控器可以在检测到该NFVI中有报警事件产生时生成报警信息，且为了对该报警信息进行处理，该NFVI中的报警监控器可以将该报警信息发送给该主虚拟机，因此，该主虚拟机可以接收该NFVI中的报警监控器发送的报警信息。
进一步地，该主虚拟机中包括一个第一BSAD，该主虚拟机通过第一BSAD，接收该NFVI中的报警监控器发送的报警信息。
其中，第一BSAD可以由该主虚拟机在接收该报警信息之前建立，本发明实施例对此不做具体限定。
进一步地，该主虚拟机通过安装的产生该报警事件的资源的本地驱动(native driver)，接收该硬件层中的报警监控器发送的第一报警信息，产生该报警事件的资源为该硬件层中与该报警事件对应的硬件资源。
由于该主虚拟机中包括多个本地驱动，该多个本地驱动分别与硬件层中的多个硬件资源一一对应，该主虚拟机可以通过任一个本地驱动和该本地驱动对应的硬件资源进行通信，因此，可以通过安装的产生该报警事件的资源的本地驱动接收该硬件层中的报警监控器发送的第一报警信息，降低了开发该主虚拟机的难度，且由于该本地驱动是与产生该报警事件的资源对应的本地驱动，因此，该主虚拟机可以通过该本地驱动，快速准确地接收到产生该报警事件的资源的第一报警信息，即提高了接收第一报警信息的效率，从而提高了网络功能虚拟化环境中的报警效率。
需要说明的是，在该主虚拟机通过安装产生该报警事件的资源的本地驱动接收第一报警信息的情况下，该主虚拟机可以通过第一BSAD接收第二报警信息，且此时，该主虚拟机不通过第一BSAD接收第一报警信息。
步骤203：该主虚拟机基于该报警信息，确定至少一个目标虚拟机标识，目标虚拟机为占用产生该报警事件的资源的用户虚拟机。
由于该NFV系统中的用户虚拟机在运行时需要占用该NFVI中的硬件资源、虚拟资源和软件资源，因此，当其中某个资源产生报警事件时，可能会导致占用产生该报警事件的资源的用户虚拟机无法正常运行，进而影响该NFV系统的稳定性和可靠性，因此，该主虚拟机可以基于该报警信息，确定占用产生该报警事件的资源的用户虚拟机，将占用产生该报警事件的资源的用户虚拟机确定为至少一个目标虚拟机。
其中，为了提高确定该至少一个目标虚拟机标识的效率，该主虚拟机可以基于该报警信息中携带的产生该报警事件的资源标识，从存储的资源标识与用户虚拟机标识之间的对应关系中，获取至少一个用户虚拟机标识，将获取的至少一个用户虚拟机标识确定为该至少一个目标虚拟机标识。
需要说明的是，该用户虚拟机标识用于在该NFV系统中唯一标识一个用 尸虚拟机。
还需要说明的是，在实际应用中，该主虚拟机还可以通过其它方式来基于产生该报警事件的资源标识，来确定至少一个目标虚拟机标识，比如，在一种可能的实现方式中，该主虚拟向该VIM发送目标虚拟机标识获取请求，该目标虚拟机标识获取请求中携带产生该报警事件的资源标识，当该VIM接收到该目标虚拟机标识获取请求时，基于产生该报警事件的资源标识，确定占用产生该报警事件的资源标识的至少一个用户虚拟机标识，将该至少一个用户虚拟机标识发送给主虚拟机，当该主虚拟即接收到该至少一个用户虚拟机标识时，将该至少一个用户虚拟机确定为该至少一个目标虚拟机标识，本发明实施例对此不做具体限定。
其中，该VIM可以为用户虚拟机分配硬件资源、虚拟资源和软件资源等资源，因此，该VIM通常会存储每个资源的资源标识和占用每个资源的用户虚拟机的用户虚拟机标识。
例如，该主虚拟机接收报警信息1且报警信息1中携带的产生报警事件1的资源标识为hardware01，因此，该主虚拟机基于如下表1所示的资源标识与用户虚拟机标识之间的对应关系中，确定资源标识hardware01对应的用户虚拟机标识为Guest 1，因此，将该用户虚拟机Guest 1确定为该至少一个目标虚拟机标识。
表1
资源标识 用户虚拟机标识
hardware01 Guest 1
hardware02 Guest 3，Guest 2
virtua1ware01 Guest 1
…… ……
需要说明的是，本公开实施例仅以上述表1所示的资源标识与用户虚拟机标识之间的对应关系为例进行说明，上述表1并不对本公开实施例构成限定。
进一步地，该主虚拟机可以在基于产生该报警事件的资源标识，从资源标识与用户虚拟机标识之间的的对应关系中确定至少一个目标虚拟机标识之前，获取该NFVI中包括的每个资源的资源标识，以及占用每个资源的用户虚拟机的用户虚拟机标识，然后分别将每个资源的资源标识和占用每个资源的用户虚 拟机的用户虚拟机标识，存储至资源标识与用户虚拟机标识之间的的对应关系中。
其中，该主虚拟机可以向该VIM发送资源分配获取请求，当该VIM接收到该资源分配获取请求时，可以将每个资源的资源标识和占用每个资源的用户虚拟机的用户虚拟机标识发送给该用户虚拟机。
进一步地，该主虚拟机通过该第一BSAD，基于该第一报警信息中携带的产生该报警事件的资源标识，确定该至少一个目标虚拟机标识。
需要说明的是，当该主虚拟机通过第一BSAD接收该报警信息且通过第一BSAD基于该第一报警信息中携带的产生该报警事件的资源标识确定该至少一个目标虚拟机标识时，由于接收该报警信息和基于该第一报警信息中携带的产生该报警事件的资源标识确定该至少一个目标虚拟机标识的是同一个驱动，因此，能够减少该主虚拟机从接收到该报警信息并确定该至少一个目标虚拟机标识所耗费的总时间，进而提高了该主虚拟机该报警事件进行报警的效率。
还需要说明的是，当该主虚拟机不是通过第一BSAD接收该报警信息时，也可以通过第一BSAD执行基于该第一报警信息中携带的产生该报警事件的资源标识确定至少一个目标虚拟机标识的操作。
进一步地，当该主虚拟机通过产生该报警事件的资源的本地驱动接收第一报警信息时，该主虚拟机通过产生该报警事件的资源的本地驱动，基于该第一报警信息中携带的产生该报警事件的资源标识，确定至少一个目标虚拟机标识，或者，该主虚拟机通过该第一BSAD，基于该第一报警信息中携带的产生该报警事件的资源标识，确定至少一个目标虚拟机标识。
需要说明的是，当该主虚拟机通过产生该报警事件的资源的本地驱动接收第一报警信息，且通过通过产生该报警事件的资源的本地驱动确定至少一个目标虚拟机标识时，由于接收第一报警信息和基于该第一报警信息中携带的产生该报警事件的资源标识确定至少一个目标虚拟机标识的是同一个驱动，因此，能够减少该主虚拟机从接收到该报警信息并确定至少一个目标虚拟机标识所耗费的总时间，进而提高了该主虚拟机该报警事件进行报警的效率。当该主虚拟机通过产生该报警事件的资源的本地驱动接收第一报警信息，且通过通过该第一BSAD确定至少一个目标虚拟机标识时，不需要对产生该报警事件的资源的本地驱动进行升级，从而避免了升级产生该报警事件的资源的本地驱动可能带来的不兼容等问题，也即是提高了该主虚拟机的可靠性，进而提高了该NFV 系统的可靠性。
步骤204：该主虚拟机基于该至少一个目标虚拟机标识，分别将该报警信息指示给至少一个目标虚拟机中VNF所对应的EM。
由于该目标虚拟机为该多个用户虚拟机中占用产生该报警事件的资源的用户虚拟机，因此，当该主虚拟机确定该至少一个目标虚拟机标识时，可以将该报警信息指示给至少一个目标虚拟机中VNF所对应的EM，能够确保至少一个目标虚拟机中VNF所对应的EM能够及时接收到该报警信息，以对该报警事件进行及时处理，进而对该NFV系统中的故障进行及时处理和修复，提高了该NFV系统的可靠性。
其中，分别将该报警信息指示给至少一个目标虚拟机中VNF所对应的EM可以包括下述两种可能的实现方式：
第一种可能的实现方式，该主虚拟机分别将该报警信息发送给至少一个目标虚拟机中VNF所对应的EM。
其中，该主虚拟机可以通过共享内存机制，分别将该报警信息发送给至少一个目标虚拟机中VNF所对应的EM。
需要说明的是，共享内存机制是该NFV系统中的一种通信机制，该主虚拟机可以在建立用户虚拟机时，为该主虚拟机和该用户虚拟机设置一个用于通信的共享内存，之后，当该主虚拟机需要向该用户虚拟机发送消息时，将该消息存储至该共享内存中，并向该用户虚拟机发送消息通知，当该用户虚拟机接收到该消息通知时，从该共享内存中获取该主虚拟机发送给用户虚拟机的消息。
还需要说明的是，在实际应用中，该主虚拟机还可以通过其它可能的机制将该报警信息发送给该目标虚拟机，比如，该主虚拟机可以通过消息传递机制将该报警信息发送给该目标虚拟机，即该主虚拟机直接将该报警信息发送给该目标虚拟机，本发明实施例对此不做具体限定。
进一步地，该主虚拟机分别将该报警信息发送给至少一个目标虚拟机中VNF所对应的EM可以包括下述两种可能情况：
第一种可能的情况，如图2D所示，该主虚拟机122中包括第一BSAD，该目标虚拟机中包括FSAD，相应地，该主虚拟机基于该至少一个目标虚拟机标识，分别将该报警信息指示给至少一个目标虚拟机中VNF所对应的EM的操作可以为：该主虚拟机基于该至少一个目标虚拟机标识，通过该第一BSAD，分别将该报警信息发送给该至少一个目标虚拟机中的FSAD，以指示该至少一 个目标虚拟机中的FSAD分别通过该至少一个目标虚拟机中的VNF，将该报警信息发送给该至少一个目标虚拟机中VNF所对应的EM。
需要说明的是，由于在该NFV系统中，该主虚拟机中包括SDD，且该多个用户虚拟机中也包括SDD，当该主虚拟机向该多个用户虚拟机发送消息时，可以通过该主虚拟机中的SDD，向该用户虚拟机中的SDD发送消息。因此，当该主虚拟机中包括一个SDD时，可以对该主虚拟机中的SDD进行升级得到第一BSAD，相应地，对目标虚拟机中的SDD进行升级得到FSAD，从而不需要在该主虚拟机和目标虚拟机中新添加发送该报警信息的驱动，减少了该主虚拟机和目标虚拟机的复杂程度。
还需要说明的是，如图2E所示，该主虚拟机122中包括第一BSAD和SDD，相应地，目标虚拟机中包括FSAD和SDD，即该主虚拟机通过第一BSAD和FSAD向该目标虚拟机发送该报警信息，通过该主虚拟机中的SDD和目标虚拟机中的SDD向目标虚拟机发送其它消息，确保该报警信息不会和其它消息相混淆，提高了发送该报警信息的效率和准确率。
还需要说明的是，当该VNF将该报警信息发送给该VNF对应的EM时，如果该VNF中也有报警事件产生，该VNF为该VNF中的报警事件生成该VNF的报警信息，并将该VNF的报警信息也发送给该EM，省去了该EM对该VNF进行检测管理的步骤，进而提高了目标虚拟机的工作效率和该VNF系统的工作效率。
第二种可能的情况，如图2F所示，该主虚拟机122中包括多个第二BSAD，该多个第二BSAD与该多个用户虚拟机的FSAD一一对应，相应地，该主虚拟机基于该至少一个目标虚拟机标识，分别将该报警信息指示给至少一个目标虚拟机中VNF所对应的EM的操作可以为：该主虚拟机基于该至少一个目标虚拟机标识，通过与该至少一个目标虚拟机对应的至少一个第二BSAD，分别将该报警信息发送给至少一个目标虚拟机中的FSAD，以指示该至少一个目标虚拟机中的FSAD分别通过该至少一个目标虚拟机中的VNF，将该报警信息发送给该至少一个目标虚拟机中VNF所对应的EM。
其中，由于该主虚拟机通过与目标虚拟机对应的第二BSAD，将该报警信息发送给目标虚拟机中的FSAD，能够避免将该报警信息发送给该多个用户虚拟机中的其它用户虚拟机，因此进一步提高了发送该报警信息的效率和准确率。
需要说明的是，当该主虚拟机中包括多个SDD时，可以对该主虚拟机中 的每个SDD进行升级得到多个第二BSAD，相应地，对目标虚拟机中的SDD进行升级得到FSAD，从而不需要在该主虚拟机和目标虚拟机中新添加发送该报警信息的驱动，减少了该主虚拟机和目标虚拟机的复杂程度，也减小了该报警方法的实现难度。
还需要说明的是，该主虚拟机中包括多个第二BSAD和多个SDD，相应地，目标虚拟机中包括FSAD和SDD，即该主虚拟机通过第二BSAD和FSAD向目标虚拟机发送该报警信息，通过该主虚拟机中的与目标虚拟机对应的SDD和目标虚拟机中的SDD向目标虚拟机发送其它消息，确保该报警信息不会和其它消息相混淆，提高了发送该报警信息的效率和准确率。
第二种可能的实现方式，该主虚拟机将该报警信息存储至报警信息池中，该报警信息池为该主虚拟机和该多个用户虚拟机均可以访问的共享存储空间，该主虚拟机基于该至少一个目标虚拟机标识，向该至少一个目标虚拟机发送报警通知，该报警通知用于指示该至少一个目标虚拟机从该报警信息池中获取该报警信息。
其中，由于该主虚拟机是将该报警信息存储至报警信息池中，而不必将该报警信息发送至该至少一个目标虚拟机，因此，当该NFV系统中的报警信息较多时，能够快速将多个报警信息存储至该报警信息池中，即能够提高该主虚拟机将该报警信息指示给该至少一个目标虚拟机的效率，进而提高了该报警方法的效率。
需要说明的是，该报警信息池可以由该主虚拟机在首次需要存储报警信息时设置，本发明实施例对此不做作具体限定。
另外，在另一种可能的实现方式中，该主虚拟机在将该报警信息存储至该报警信息池中时，也可以不向该至少一个目标虚拟机发发送该报警通知，而是分别由该至少一个目标虚拟机每隔特定时长，从该报警信息中获取该主虚拟机需要发送给该至少一个目标虚拟机的报警信息。
其中，由于该主虚拟机只需要将该报警信息存储至该报警信息池中，进一步减少了该主虚拟机与该至少一个目标虚拟机之间的交互次数，提高了该主虚拟机将该报警信息指示给该至少一个目标虚拟机的效率，也即是进一步提高了该报警方法的报警效率。
还需要说明的是，该特定时长可以由该多个用户虚拟机在从该报警信息中获取报警信息之前确定，该特定时长可以是1毫秒或者3毫秒，当然，在实际 应用中，该特定时长还可以通过其它方式确定，该特定时长还可以是其它值，本发明实施例对此不做具体限定。
进一步地，在第二种可能的实现方式中，该主虚拟机可以通过第一BSAD将该报警信息存储至报警信息池中并基于该至少一个目标虚拟机标识，向该至少一个目标虚拟机发送报警通知，或者，该主虚拟机也可以通过与该目标虚拟机对应的第二BSAD，该报警信息存储至报警信息池中并基于该至少一个目标虚拟机标识，向该至少一个目标虚拟机发送报警通知，本发明实施例对此不做具体限定。
进一步地，当该至少一个目标虚拟机中VNF所对应的EM基于该报警信息对该报警事件进行处理时，该EM可以基于该报警信息中携带的产生该报警事件的资源标识，确定产生该报警事件的资源，基于该报警信息中携带的该报警事件说明，对该报警事件进行处理，比如，立即启动迁移流程等。
其中，当该报警事件的不同时，所需要采取处理策略也不同，本发明实施例对此不做具体限定。
在本发明实施例中，首先，该主虚拟机可以接收NFV系统包括的NFVI中的报警监控器发送的报警信息，并基于该报警信息中携带的产生该报警事件的资源标识，从该NFV系统中安装的多个用户虚拟机中确定占用产生该报警事件的资源的至少一个目标虚拟机，将该报警信息指示给该至少一个目标虚拟机中VNF所对应的EM，由于该报警信息不需要通过VIM和VNFM进行多次转发，提高将该报警信息发送给EM的效率，能够确保该至少一个目标虚拟机中VNF所对应的EM能够及时接收到该报警信息，以对该报警事件进行及时处理，进而对该NFV系统中的故障进行及时处理和修复，提高了该NFV系统的可靠性。其次，由于该主虚拟机中包括该NFVI中硬件层包括的多个硬件资源的本地驱动，因此，可以通过产生该报警事件的资源的本地驱动接收与产生该报警事件的资源对应的第一报警信息，并基于第一报警信息中携带的产生该报警事件的资源标识确定占用产生该报警事件的资源的至少一个目标虚拟机，从而不必在该主虚拟机中新设置驱动，减小了该主虚拟机的复杂度和该NFV系统的复杂度。最后，该主虚拟机可以将该报警信息发送给该目标虚拟机中VNF所对应的EM，以提高指示该报警信息的准确率，或者将该报警信息存储至报警信息池中，由该至少一个目标虚拟机从该报警信息池中获取该报警信息，提高了该主虚拟机将该报警信息指示给该至少一个目标虚拟机的效率，进而提 高了该报警方法的报警效率。
