用于克隆 Linux 虚拟机的示例脚本

您可以自定义和使用以下示例脚本来克隆任意数量的虚拟机 (VM)。

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，您可以从位于以下位置的 Horizon 7 文档页面找到该版本：https://docs.vmware.com/cn/VMware-Horizon-7/index.html。

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
克隆类型，只能为完整克隆
是否禁用 vSphere 虚拟机控制台

脚本执行

下面是执行脚本时显示的消息：

PowerCLI C:\scripts> .\CloneVMs.ps1
Your vCenter address: 10.117.44.17
Your vCenter admin user name: administrator
Your vCenter admin user password: *******
Clone Type<"Full"> : Full
Disable vSphere VM Console ("yes" or "no", recommend "yes") : yes

克隆过程所花的时间取决于桌面计算机数，可能需要几分钟到几小时的时间。要确认该过程完成，请从 vSphere Client 中确保最后一个桌面虚拟机已打开电源，具有唯一的主机名，并且 VMware Tools 正在运行。
