尽pipe具有pipe理权限，但无法使用PowershellclosuresHyperV虚拟机

我创build了一个符合我需求的脚本，我将在这里发布。

该脚本执行以下任务：

• 遍历所有列出的物理主机
• 遍历所有未排除的VM
• 正常closures虚拟机并等待关机完成
• 将目标VM的所有VHD文件（一次一个）同步BITS传输到指定位置
• 传输完成后，启动将以VM为目标

该脚本可以在远程物理主机上运行，​​不需要在本地运行。 请务必使用pipe理凭据运行该脚本，否则将无法正常工作。

我正在使用Windows Server 2008 R2，因此我无法访问Windows Server 2012中所有可用的命令。

而且，这里也是“剧本小子”的终极performance。 我已经将4个不同的脚本混合在一起，然后在其上添加了一些逻辑。 原谅语法不一致等

这个脚本是从我使用的一个独立的企业系统手抄录的，所以它可能有一些拼写错误。 我还没有试过直接执行这个脚本。 在我的系统上的似乎工作得很好。
