Description

一种恢复、升级虚拟机的方法及装置 技术领域
本发明涉及云桌面领域,尤其涉及一种恢复、升级虚拟机的方法及装置。
背景技术
云桌面,是基于对计算机硬件资源实施虚拟化技术,使其被虚拟成多个虚拟计算机,并在虚拟计算机上可以直接运行未经任何改动的桌面操作系统。同时还提供支持类虚拟化技术的操作系统,应用可直接运行于该桌面操作系统之上。云桌面系统包括管理中心、主机服务端、存储模块和客户端。管理中心负责资源的创建、维护和分配;主机服务端提供了网络、块设备I/O支持;存储模块负责用户数据的保存和访问;客户端负责云资源的连接和显示。
虚拟计算机一般分为桌面虚拟机和普通虚拟机。桌面虚拟机一般是提供给用户直接使用的,用户登录虚拟机后,可以将该虚拟机当成普通的PC直接使用,该类型虚拟机主要考虑各类应用的使用支持,常见的桌面操作系统有xp、win7、win8等。普通虚拟机一般是当成服务器来使用的,不用分配给用户直接使用,支持常用的服务器操作系统有windows 2003、windows 2008、windows 2010以及各类linux系统。
虚拟桌面登录认证方式常见的有本地认证和AD(Active Directory)域控认证两种方式。本地认证方式将用户的用户名和密码存在本地数据库。AD域控将信息存在专门的AD服务器上,安全集中管理,统一安全策略。AD域控制器的作用相当一个门卫,它包含了由这个域的账户密码、管理策略等信息构成的数据库。当一台计算机登录域时,域控制器首先要鉴别这台电脑是否是属于这个域的,用户使用的登录账号和密码是否正确。如果正确则允许计算机登入这个域,使用该域内其有权限访问的任何资源,像文件服务器,打印服务器(也就是说域控制器仅起到一个验证作用,访问其他资源并不需要再跟域控制器扯上关系);如果不正确则不允许计算机登入,这时计算机将无法访问域内任何资源,这在一定程度上保护了企业网络资源。
现在惯用的虚拟机恢复策略是对虚拟机做备份,虚拟机异常时,使用备份进行恢复。这种恢复的一大缺陷是不能对备份后的虚拟机操作进行恢复。
现有技术中通过域控下发的方式进行软件的批量升级,域控只能将软件批量下发到各个虚拟机,通知用户自己去安装或管理员进入桌面虚拟机去一台台安装。

具体实施方式
为使本发明要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
现有技术中,利用虚拟机模板创建虚拟机的详细过程如下:
如图1所示,通知虚拟机模板创建虚拟机1,在虚拟机模板的磁盘节点A下拉2个子节点B、M出来,分别成为虚拟机1和虚拟机模板的子节点。此时节点A成为虚拟机模板和虚拟机1的共同父节点,B、M因为是新建的节点(没有在节点上进行操作),这2个磁盘节点实际占用的空间很小甚至没有数据。因此创建的过程非常快(10S左右)。
如图2所示,通知虚拟机模板创建虚拟机2,在虚拟机模板的子节点M下拉2个子节点C、D出来,分别成为虚拟机2和虚拟机模板的子节点。同理,C、D是新建的节点,这2个磁盘节点实际占用的空间很小甚至没有数据。因此创建虚拟机2的过程也非常快(10S左右)。
如图3所示,对虚拟机和虚拟机模板的父节点进行判空,如果为空,删除该空的父节点。虚拟机2和虚拟机模板的父节点M是空节点,删除该节点。最后形成如图4所示的虚拟机模板创建虚拟机的磁盘节点树形图。
本发明基于上述现有技术提供了一种恢复虚拟机的方法,如图5所示,包括:
步骤S100、删除所选定的虚拟机,并保留虚拟机的磁盘信息和注册表信息,其中磁盘信息至少包括:系统盘信息;
步骤S200、通过虚拟机模板创建VHD虚拟机;
步骤S300、将虚拟机的磁盘信息和注册表信息导入到VHD虚拟机中。
具体地,保留选定虚拟机的磁盘信息和注册表信息,依据虚拟机模板创建VHD虚拟机,将保存的虚拟机的磁盘信息和注册表信息导入到新创建的VHD虚拟机中,恢复虚拟机的应用程序和数据,快速、智能、完全地恢复虚拟机。
在本发明上述实施例中,删除所选定的虚拟机,并保留虚拟机的磁盘信息
和注册表信息,具体为:
在磁盘节点树形结构中删除所选定的虚拟机的第一子节点,将虚拟机的注册表信息存储到虚拟机的磁盘信息里,并保留虚拟机的磁盘信息。
如图6所示,删除选定的虚拟机1的子节点B,保留虚拟机1所有磁盘(包括系统盘C)信息,并自动保留虚拟机1的注册表信息,将注册表信息存储到虚拟机的磁盘信息里,将虚拟机1的磁盘节点A+B整合成独立磁盘a。
在本发明上述实施例中,通过虚拟机模板创建VHD虚拟机,具体为:
在磁盘节点树形结构中选取与虚拟机的第一子节点具有相同的父节点的虚拟机模板的第二子节点,并通过虚拟机模板的第二子节点创建VHD虚拟机的第三子节点,通过父节点、虚拟机模板的第二子节点和VHD虚拟机的第三子节点形成VHD虚拟机。
如图7所示,使用虚拟机模板快速创建VHD虚拟机即虚拟机3(10S左右),创建过程:在虚拟机模板的子节点D下拉2个子节点E、F出来,分别成为虚拟机3和虚拟机模板的子节点。创建虚拟机3后的磁盘节点树形变化图为:从虚拟机模板的子节点D下拉了2个子节点E、F,形成了虚拟机3,这样虚拟机3的节点为A+D+E,虚拟机模板的节点为A+D+F。
在本发明上述实施例中,该方法还包括:
对虚拟机模板的第二子节点进行判空操作,当虚拟机模板的第二子节点为空节点时,删除虚拟机模板的第二子节点。
为了防止虚拟机节点无节制的增多,子节点会判定父节点是否为空,如果为空则删除空节点。如图8所示,D节点是空节点(里面没有内容),判空后删除。
在本发明上述实施例中,将虚拟机的磁盘信息和注册表信息导入到VHD虚拟机中,如图9所示,具体包括:
步骤S301、将虚拟机的系统盘信息导入VHD虚拟机,作为VHD虚拟机的数据盘信息;
步骤S302、将虚拟机的注册表信息导入VHD虚拟机的注册表中,根据VHD虚拟机中的数据盘信息更新VHD虚拟机的注册表信息。
如图10所示,在新虚拟机(虚机3)上挂载虚拟机1保留的磁盘信息(即独立磁盘a),作为新虚拟机的数据盘。其中将虚拟机1的系统盘C作为新虚拟机的数据盘E,修改保存的虚拟机1的注册表信息中C盘为E盘。将保存虚拟机1的注册表信息导入新虚拟机中。这样可以尽可能的恢复虚拟机1的各种应用和数据,不用重新安装。
本发明实施例还提供一种升级虚拟机的方法,如图11所示,包括:
步骤S400、将虚拟机模板转换成新虚拟机,并在新虚拟机内安装新应用或补丁;
步骤S500、将安装新应用或补丁后的新虚拟机转换为新虚拟机模板;
步骤S600、将新虚拟机模板的子节点和新虚拟机模板的父节点进行整合得到一个新的父节点来替换新虚拟机模板的原父节点。
具体的,如图12和13所示,通过在新虚拟机内安装新应用或补丁,将安装新应用或补丁后的新虚拟机转换为新虚拟机模板,此时新虚拟机模板中包含了新的应用或补丁,通过父节点替换的方式,可以实现虚拟机内部新应用安装和补丁升级,完全做到批量、自动的安装或升级,效率得到明显提升。
在本发明上述实施例中,步骤S400中在新虚拟机内安装新应用或补丁,具体为:
在磁盘节点树形结构中选定新虚拟机的子节点,在新虚拟机的子节点上安装新应用或补丁。
如图12所示,在虚拟机4内安装新的应用或补丁,应用或补丁的安装是在虚拟机4的子节点D上进行操作的,不影响其他虚拟机的在线使用。
在本发明上述实施例中,如图14所示,步骤S600具体包括:
步骤S601、在磁盘节点树形结构中选定新虚拟机模板的子节点和新虚拟机模板的父节点作为新虚拟机模板的新父节点来代替新虚拟机模板的原父节点;
步骤S602、将新虚拟机模板的子节点和新虚拟机模板的父节点进行整合,得到新虚拟机模板的新父节点。
如图15所示,将新虚拟机模板的父节点和子节点整合替换原来的父节点。替换后的虚拟机1、虚拟机2和新虚拟机模板的父节点是A+D,虚拟机1、虚拟机2及新虚拟机模板的差异子节点分别为B、C、E。将父节点A+D整合成一个节点F,参考图16整合父节点磁盘节点树形变化图为:虚拟机1、虚拟机2和新虚拟机模板整合后的父节点是F,虚拟机1、虚拟机2和新虚拟机模板的差异子节点分别为B、C、E。
