概述

有时候需要大量创建虚拟机，这时候如果手动克隆等话比较耗时耗力，如果能自动化克隆需要的虚拟机，无疑是事半功倍的操作，这里记录并分享一下使用PowerShell来自动克隆虚拟机的方式，效果如下图所示

脚本

$vc = '192.168.205.253' #VCenter IP
Connect-VIServer -Server $vc -username "administrator@vsphere.local"

$vmhost = Get-VMHost "192.168.205.1"
$ResourcePool = Get-ResourcePool -Location $vmhost -Name "Resources"

$namestart="压力测试虚拟机"
$template="2019-DC-TEMP"
$datastore="ESXi01-M2-02"

$ipstart="192.168.1."
$endipscope=100..116

#循环生成虚拟机
foreach ($endip in $endipscope) 
{
    $custsysprep = Get-OSCustomizationSpec myCustSpec
    
    $ip=$ipstart+$endip
    $name=$namestart+$endip

    $custsysprep | Set-OScustomizationSpec -NamingScheme fixed -NamingPrefix $name -Confirm:$false
    $custsysprep | Get-OSCustomizationNicMapping | Set-OSCustomizationNicMapping -IpMode UseStaticIP -IpAddress $ip -SubnetMask 255.255.255.0 -Dns 192.168.1.1 -DefaultGateway 192.168.1.1 -Confirm:$false
    
    New-VM `
        -Name $name `
        -Template $template `
        -VMHost $vmhost `
        -ResourcePool $ResourcePool `
        -Datastore $datastore `
        -OSCustomizationspec $custsysprep `
        -Confirm:$false

    Start-Sleep -Seconds 1
}
