您可以自定义和使用以下示例脚本来在多个虚拟机 (VM) 上执行操作。这些操作包括打开电源、关闭电源、关闭、重新启动和删除虚拟机。

该脚本可以从 vCenter Server 中删除虚拟机,但不能从 View 中删除虚拟机。

要复制和粘贴不包含分页符的脚本内容,请使用此主题的 HTML 版本,您可以从位于 https://www.vmware.com/support/pubs/view_pubs.htmlHorizon 7 文档页面找到该版本。

脚本输入

此脚本将读取一个输入文件,用于部署 Linux 桌面的示例 PowerCLI 脚本的输入文件中对此做了介绍。此脚本还会以交互方式要求提供以下信息:

  • vCenter Server 的 IP 地址
  • vCenter Server 的管理员登录名称
  • vCenter Server 的管理员密码
  • 要执行的操作,可以是打开电源、关闭电源、关闭客户机、重新启动虚拟机、重新启动虚拟机客户机或删除虚拟机。
  • 虚拟机上的操作之间的等待时间(以秒为单位)。

脚本执行

下面是执行脚本时显示的消息:

PowerCLI C:\scripts> .\VMOperations.ps1
Your vCenter address: 10.117.44.17
Your vCenter admin user name: administrator
Your vCenter admin user password: *******
--------------------------------------------------
Select action: 1). Power On 2). Power Off 3) Shutdown VM Guest 4). Restart VM 5). Restart VM Guest 6). Delete VM: 1
Wait time (seconds) between each VM: 20
--------------------------------------------------
Your selection is 6). Delete VM

对于打开电源、重新启动虚拟机和重新启动虚拟机客户机操作,将虚拟机之间的等待时间指定为至少 20 秒可避免出现引导风暴的情况,否则可能导致某些操作失败。
