Vmware 使用多线程PowerCLI并行克隆多个VM
我承担了在VMware中克隆大量虚拟机的任务。我希望尽可能地自动化克隆向导，而不是通过克隆向导点击数百次 我已经对模板机进行了配置并“密封”。一旦它被克隆并通电，新克隆的实例将启动，在那里等待一段时间，然后进行sysprep，等等。这大约需要20分钟左右 我找到了一个非常好的网站，它能做我需要的一切。我对它做了一点修改，所以我不必更改值，也不必为流程的每个步骤重新保存脚本。我没有在整个脚本中使用$Step计数器，而是简单地用一些启动睡眠延迟来代替它。此时，它工作正常，并成功地从CSV文件克隆了它读入的所有机器。每台机器大约需要35分钟才能准备就绪（机器移动到不同的AD OU） 唯一的问题是它以串行方式运行，等待整个过程（克隆、更改VLAN、引导计算机并等待域加入，以及将最终计算机对象移动到其他AD OU）完成，然后再启动另一个克隆 我真正想做的是对它进行多线程处理，使整个操作更快。我在测试中发现，vSphere中的克隆一旦运行大约五个单独的克隆作业，就会开始减速，因此我想修改此脚本以同时运行四个克隆（执行整个工作流）Vmware 使用多线程PowerCLI并行克隆多个VM,vmware,powercli,Vmware,Powercli,我承担了在VMware中克隆大量虚拟机的任务。我希望尽可能地自动化克隆向导，而不是通过克隆向导点击数百次 我已经对模板机进行了配置并“密封”。一旦它被克隆并通电，新克隆的实例将启动，在那里等待一段时间，然后进行sysprep，等等。这大约需要20分钟左右 我找到了一个非常好的网站，它能做我需要的一切。我对它做了一点修改，所以我不必更改值，也不必为流程的每个步骤重新保存脚本。我没有在整个脚本中使用$Step计数器，而是简单地用一些启动睡眠延迟来代替它。此时，它工作正常，并成功地从CSV文件克隆了它
有什么想法吗？如果需要，我可以粘贴代码。您最多可以从一个模板并行克隆8个虚拟机。如果使用-RunAsync运行新vm。使用-RunAsync，命令立即返回，输出由一个或多个任务对象组成 如果您想克隆多个虚拟机，以下内容应该会有所帮助。循环一下

下面是我在过去几天编写的一个脚本，它将VM模板部署到我们大约650台服务器上。它从全国不同数据中心的3个不同VM主机部署。它同时从欧文基地部署了5架，从普拉诺基地部署了15架，从亚特兰大基地部署了15架。周一至周五晚上7点至早上6点，周六和周日全天营业。如果它在任何其他时间运行，它将退出 当我试图弄清楚如何在使用Start Job调用函数时将多个参数传递给函数时，我已经没有时间了，所以我只是为这三个位置创建了一个单独的函数 使用此脚本，我们能够在一周内的夜间和周末将新RDC映像部署到650多个位置 param( [参数（ValueFromPipelineByPropertyName=$true）] [字符串]$InputFile=$null )
