Question

我承担了在VMware中克隆大量虚拟机的任务。我不想通过克隆向导点击数百次，而是希望尽可能自动化。

我已经配置了模板机并且已经“密封”了。一旦它被克隆并打开电源，新克隆的实例将启动，在系统中进行一段时间，然后进行系统预测等。这需要大约20分钟左右。

我找到了一个非常好的script over on MSFT TechNet，可以完成我需要做的一切。我已经对它进行了一些修改，因此我不必更改值并为该过程的每个步骤重新保存脚本。在整个脚本中我没有使用$ Step计数器，而是将其替换为一些启动 - 睡眠延迟。此时，它工作正常，并成功克隆从CSV文件中读取的所有计算机。每台机器在准备好之前大约需要35分钟（机器被移动到不同的AD OU）。

唯一的问题是它正在以串行方式运行，等待整个进程（克隆，更改VLAN，启动计算机并等待域加入，并将最终机器对象移动到另一个AD OU），然后再开始另一个克隆。< / p>

我真正喜欢的是多线程，以使整个操作更快。我在测试中发现，一旦大约五个单独的克隆作业正在运行，vSphere中的克隆开始变慢，所以我想修改此脚本以一次运行四个克隆（完成整个工作流程）。

有什么想法吗？如果需要，我可以粘贴代码。

Answer 1

您可以从一个模板最多并行克隆8个vms。如果使用-RunAsync运行new-vm。使用-RunAsync该命令立即返回，输出包含一个或多个Task对象。

如果要克隆多个VM以下应该有所帮助。只是循环它。

Write-host "Deploying VM " -ForegroundColor Green -NoNewline; Write-Host $vmname -ForegroundColor Yellow
get-OScustomizationspec $cs | get-OScustomizationNicMapping | set-OSCustomizationNicMapping -IpMode UseStaticIP -IpAddress $vm.IP -SubnetMask $vm.subnet -DefaultGateway $vm.gateway -Dns $vm.Dns1, $vm.Dns2

$vms = New-VM -Name $vm.Name -Location $vm.cluster -VMhost $vm.vmhost -Template $vm.template -Datastore $vm.datastore -OSCustomizationSpec $cs -confirm:$false **-RunAsync**

if ($vm1.error) {
    Write-Host "Error in deploying $vmname" -ForegroundColor Red
}

以下是我过去几天编写的脚本，该脚本将VM模板部署到大约650台服务器中。它从全国各地不同数据中心中的3个不同VM主机部署它。它同时从Irving位置部署了5个，从Plano部署了15个，从Atlanta部署了15个。它的运行时间为周一至周五的晚上7点至凌晨6点，以及周六和周日的全天。如果再运行其他时间，则退出。

在尝试使用Start-Job调用该函数时如何找出多个参数传递给函数时，我用光了时间，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，我们能够在大约一周的晚上和周末将新的RDC映像部署到650多个位置。
