技术领域
本申请涉及一种虚拟机内部配置的修改方法、系统及装置。
背景技术
在虚拟化平台中，由于虚拟机和主机之间处于隔离状态，无法通过主机直接操控虚拟机内部，因此会在虚拟机内部安装一个代理服务，如vmtools(一种虚拟机工具)服务，该服务会从虚拟化平台接收指令，并根据该指令在虚拟机中执行相应的操作，这样虚拟化平台便可直接通过管理界面来实现一些修改虚拟机内部配置的功能。
当虚拟机处于关机状态时，若虚拟化平台下发了修改虚拟机内部配置的指令，则当虚拟机开机时，会创建一个进程来周期性查询虚拟机内部vmtools服务的状态，目的是在vmtools服务启动运行后，将修改虚拟机内部配置的指令下发至vmtools服务。但是，虚拟机创建的进程存在一个超时时间，若虚拟机在开机阶段速度较慢(例如检查磁盘等)，在进程超时时vmtools服务还未启动运行，则向vmtools服务下发指令失效，导致修改虚拟机内部配置失败。

具体实施方式
为使本申请实施例的技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本 申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
请参照图1，图1为本申请实施例提供的一种虚拟机内部配置的修改方法的流程图。
该虚拟机内部配置的修改方法应用于内部安装有代理服务的虚拟机，代理服务用于在自身启动后，通过系统中与虚拟机对应的虚拟网卡向预设IP地址发送数据请求。虚拟机内部配置的修改方法包括：
步骤S1：在有目标虚拟网卡向预设IP地址发送数据请求时，根据预设虚拟网卡与虚拟机的对应关系，确定与目标虚拟网卡对应的目标虚拟机。
具体地，系统中有多个虚拟机，每个虚拟机内部均安装有代理服务(如vmtools服务)。多个虚拟机与系统中的多个虚拟网卡具有一一对应关系。每个虚拟机内的代理服务在自身启动后，均会主动通过所在虚拟机对应的虚拟网卡向预设IP(Internet Protocol，互联网协议)地址发送数据请求。步骤S1可以包括：响应于目标虚拟网卡向预设IP地址发送数据请求，根据预设虚拟网卡与虚拟机的对应关系，确定与目标虚拟网卡对应的目标虚拟机。
基于此，通过监测系统中所有虚拟网卡，判断是否有虚拟网卡向预设IP地址发送数据请求，在有目标虚拟网卡(系统中任一虚拟网卡)向预设IP地址发送数据请求时，根据预设虚拟网卡与虚拟机的对应关系，确定与目标虚拟网卡对应的目标虚拟机。步骤S2：从用于存储系统中各虚拟机的配置数据的数据库中，获取与目标虚拟机对应的目标配置数据。
具体地，系统的数据库中存储有系统中各虚拟机的配置数据，所以可从数据库中获取与目标虚拟机对应的目标配置数据，供后续修改目标虚拟机的内部配置使用。
更具体地，数据库中存储的配置数据可为json格式(JavaScript Object Notation,JavaScript对象简谱，是一种轻量级的数据交换格式)，如{“user”:“inspur”，“passwd”：“123456”}，便于数据处理。
步骤S3：将包含目标配置数据的修改指令发送给目标虚拟机对应的目标代理服务，以使目标代理服务基于目标配置数据修改目标虚拟机的内部配置。
具体地，在获取与目标虚拟机对应的目标配置数据之后，将包含目标配置数据的修改指令发送给目标虚拟机对应的目标代理服务。目标代理服务在接收到包含目标配置数据的修改指令后，基于目标配置数据修改目标虚拟机的内部配置。具体地，可通过调用目标代理服务接口来修改目标虚拟机的内部配置。
本申请实施例提供的虚拟机内部配置的修改方法中，代理服务并非作为被动方被动等待指令，而是作为主动方主动请求数据，系统在代理服务主动请求数据时，向代理服务下发相应数据。代理服务可主动请求数据，说明代理服务在正常运行，这样可以避免出现因代理服务启动超时导致虚拟机内部配置修改失败的问题。
在一些实施例中，虚拟机内部配置的修改方法还包括：
在目标代理服务接收到修改指令后，停止目标代理服务通过目标虚拟网卡向预设IP地址发送数据请求的操作。
在目标代理服务接收到修改指令后，停止目标代理服务通过目标虚拟网卡向预设IP地址发送数据请求的操作，可以避免目标代理服务重复修改目标虚拟机的内部配置。
在一些实施例中，停止目标代理服务通过目标虚拟网卡向预设IP地址发送数据请求的操作的过程，包括：
为目标代理服务创建一个信号文件，以使目标代理服务在信号文件创建成功后，停止通过目标虚拟网卡向预设IP地址发送数据请求。
具体地，可通过为目标代理服务创建一个信号文件作为目标代理服务停止通过目标虚拟网卡向预设IP地址发送数据请求的标志，即本申请实施例在目标代理服务接收到修改指令后，为目标代理服务创建一个信号文件(信号文件也可由目标代理服务在接收到修改指令后自主生成)，目标代理服务在信号文件创建成功后，停止通过目标虚拟网卡向预设IP地址发送数据请求。
在一些实施例中，虚拟机内部配置的修改方法还包括：
检测数据库中与目标虚拟机对应的目标配置数据是否发生变化；
若是，则删除信号文件，以使目标代理服务在信号文件删除成功后，重新通过目标虚拟网卡向预设IP地址发送数据请求。
考虑到数据库中各虚拟机对应的配置数据有可能发生变化，此时又有重新修改虚拟机的内部配置的必要，所以可以检测数据库中与目标虚拟机对应的目标配置数据是否发生变化；若发生变化，则删除为目标虚拟机对应的目标代理服务创建的信号文件，目标代理服务在信号文件删除成功后，重新通过目标虚拟网卡向预设IP地址发送数据请求；若未发生变化，说明没有重新修改目标虚拟机的内部配置的必要，则保留为目标虚拟机对应的目标代理服务创建的信号文件。需要说明的是，虚拟机上的代理服务可始终处于运行状态，可随时处理配置数据。
具体地，虚拟机内部配置的修改方法可包括：检测数据库中与目标虚拟机对应的目标配置数据是否发生变化；响应于发生变化，删除信号文件，以使目标代理服务在信号 文件删除成功后，重新通过目标虚拟网卡向预设IP地址发送数据请求。
在一些实施例中，在有目标虚拟网卡向预设IP地址发送数据请求时，根据预设虚拟网卡与虚拟机的对应关系，确定与目标虚拟网卡对应的目标虚拟机，从用于存储系统中各虚拟机的配置数据的数据库中，获取与目标虚拟机对应的目标配置数据的过程，包括：
在有目标虚拟网卡向预设IP地址发送数据请求时，查询目标虚拟网卡的目标MAC地址；
根据预设MAC地址与虚拟机ID的对应关系，确定与目标MAC地址对应的目标虚拟机ID；
根据目标虚拟机ID，从用于存储系统中各虚拟机的配置数据的数据库中，获取与目标虚拟机对应的目标配置数据。
具体地，本申请实施例的虚拟网卡与虚拟机的对应关系具体体现为虚拟网卡的MAC(Media Access Control，媒体存取控制)地址与虚拟机ID(Identity document，身份标识号)的对应关系。不同虚拟网卡的MAC地址不同，MAC地址可用于标识虚拟网卡。基于此，在有目标虚拟网卡向预设IP地址发送数据请求时，先查询目标虚拟网卡的目标MAC地址，再根据预设MAC地址与虚拟机ID的对应关系，确定与目标MAC地址对应的目标虚拟机ID；从而根据目标虚拟机ID，从数据库中获取与目标虚拟机对应的目标配置数据。
在一些实施例中，在有目标虚拟网卡向预设IP地址发送数据请求时，查询目标虚拟网卡的目标MAC地址，包括：响应于有目标虚拟网卡向预设IP地址发送数据请求，查询目标虚拟网卡的目标MAC地址。
在一些实施例中，预设IP地址的预设过程，包括：
将系统中可用的IP地址按照利用率进行排序；
将利用率最低的IP地址作为代理服务发送数据请求的IP地址。
在一些实施例中，虚拟机内部配置的修改方法，还包括：将所述系统中可用的IP地址按照利用率进行排序；将利用率最低的IP地址作为所述代理服务发送数据请求的所述预设IP地址。
为了避免IP地址使用冲突，将系统中可用的IP地址中利用率最低的IP地址作为代理服务发送数据请求的预设IP地址例如在一些情况下，将169.254.169.254这一基本不被使用的IP地址作为代理服务发送数据请求的预设IP地址。基于此，先将系统中可用的IP地址按照利用率进行排序，得到利用率最低的IP地址就相当于得到代理服务发送数据请 求的预设IP地址。
综上，虚拟机内的代理服务与虚拟机所在的主机共同完成主动数据请求-被动数据接收这一过程，解决了传统的代理服务只能被动接收数据所产生的问题，并通过信号文件的创建与删除，实现灵活改动虚拟机内部配置的功能。
