clone vm更改网络标识

我正在尝试编写（powershell / powercli）克隆我们的QA环境（261台服务器）。 基本上我想创建每个服务器的新副本，只需更改VM名称，主机名和IP地址。理想情况下，我想在域上使用新克隆（其中90％是Windows操作系统）。我的许多服务器都有许多大型硬盘驱动器，这些硬盘驱动器并不都适用于一个数据存储区，因此我必须能够克隆到多个数据存储区。

我开始使用New-VM来获得足够小的服务器以适应一个数据存储，但OSCustomization仅在大约30％的时间内工作。其余的时间我必须登录到Windows并手动从域中删除以重命名主机名。大多数时候Set-OSCustomizationNicMapping工作但是指定-Domain -DomainUsername / Password永远不会工作（充其量它重命名服务器并放入“域名”工作组，但它永远不会将它连接到域）。

要解决多数据存储问题，我发现$ vm.ExtensionData.CloneVM使用VMWare.Vim.VirtualMachineRelocateSpec来指定哪些硬盘驱动器去哪些数据存储并且效果很好，但我不知道如何自定义主机名或NIC设置

因此基本要求是：克隆到多个数据存储区，更改主机名和IP设置。有没有人有任何建议或解决方案？

以下是我的一些代码段：

为New-VM设置OSCustomizationSpec 

$spec = New-OSCustomizationSpec -Name "PowerCLI Scripting for $NewHostName" -Spec "PowerCLI Scripting" -WhatIf:$False
Set-OSCustomizationSpec $spec -Workgroup "WORKGROUP" -DomainUsername "qajoin@qa.company.com" -DomainPassword (Get-Password -Username "qa\qajoin") -ProductKey $ProductKey -AdminPassword (Get-Password $Script:LuserName) | Out-Null
Get-OSCustomizationSpec "PowerCLI Scripting for $NewHostName" `
| Get-OSCustomizationNicMapping `
| Set-OSCustomizationNicMapping `
-IPMode:UseStaticIP `
-IPAddress $NewIPAddress `
-SubnetMask "255.255.248.0" `
-DNS "10.26.40.115","10.26.40.116" `
-DefaultGateway $NewDFGW | Out-Null

New-VM命令：

$VM = New-VM -VMHost $VMHost -VM $Hostname -Name $NewHostName -Description "$Description" -OSCustomizationSpec "PowerCLI Scripting for $NewHostName" -Location (Get-Folder -Id $Location) -Datastore $MostFreeSpace -ErrorAction Stop

这是多数据存储克隆：

$VMXtargetDatastore = Get-Datastore ($MapInfo | Where-Object {$_.Name -eq "Hard disk 1"}).NewDataStore

#Create an empty CloneSpec
$spec = New-Object VMware.Vim.VirtualMachineCloneSpec 
$spec.Template = $false
 $spec.PowerOn = $false

 #Create a RelocateSpec (datastore is target for .vmx)
$spec.Location = New-Object VMware.Vim.VirtualMachineRelocateSpec
$spec.Location.Datastore = $targetDatastore.ExtensionData.MoRef

#For each disk in the current vm
#  create a new DiskLocator spec
#  populate the datastore and diskid from the current harddisk
#  add the spec to RelocateSpec from above
Get-HardDisk -VM $Origvm | %{
    $disk = New-Object VMware.Vim.VirtualMachineRelocateSpecDiskLocator
    $disk.diskId = $_.ExtensionData.Key #2001,2002,2003,...
    $DiskLabel = $_.ExtensionData.DeviceInfo.Label
    #$disk.datastore = $_.ExtensionData.Backing.Datastore #type=datastore value=datastore-2790
    $dsname = ($MapInfo | Where-Object {$_.Name -eq $DiskLabel}).NewDataStore
    $ds = Get-Datastore -Name $dsname
    $disk.datastore = $ds.id
    $spec.Location.Disk += $disk
}

$CustSpec = New-Object VMware.Vim.CustomizationSpec
$origvm.ExtensionData.CloneVM((Get-Folder -Id $folder).ExtensionData.MoRef, $targetName, $spec)

我猜测使用ExtensionData.CloneVM方法的下一步是声明CustomizationIdentitySettings的新对象，但我找到的文档（http://pubs.vmware.com/vi3/sdk/ReferenceGuide/vim.vm.customization.IdentitySettings.html）并没有真正帮助（可能因为设置因人而异）操作系统？）然后将该对象添加到我的$ spec对象。 OSCustomizationNicMapping（http://www.vmware.com/support/developer/PowerCLI/PowerCLI41U1/html/OSCustomizationNicMapping.html）也是如此，但我不能从pubs中获取足够的信息来弄清楚如何构建我的$ spec对象。

你不能复制到孤立的环境吗？只需构建一组额外（隔离）VLAN并复制所有虚拟机，保留IP /名称，仅在虚拟机级别切换VLAN。

我终于找到了这个页面：http://www.vmdev.info/?p=202 我从他们展示的示例开始，它起作用，所以我一直在添加CloneSpec字段，直到我得到我想要的：

    $nicMaparray = @()
    $FirstNic = New-Object VMware.Vim.CustomizationAdapterMapping
        $FirstNic.adapter = New-Object VMware.Vim.CustomizationIPSettings
            $FirstNic.adapter.dnsDomain = $domain
            $FirstNic.adapter.dnsServerList = "10.26.40.115","10.26.40.116"
            $FirstNic.adapter.gateway = $DefGW
            $FirstNic.adapter.ip = New-Object Vmware.Vim.CustomizationFixedIp
                $FirstNic.adapter.ip.IpAddress = $NewIP
            $FirstNic.adapter.subnetMask = "255.255.248.0"
    $nicMaparray += $FirstNic

    $folderobj = $origvm.parent
    $vm = Get-VM $sourceName | Get-View
    $cloneName = $targetName
    $cloneFolder = Convert-PathToFolderObject -FolderPath $folderpath
    $cloneSpec = new-object Vmware.Vim.VirtualMachineCloneSpec
    $cloneSpec.Location = new-object Vmware.Vim.VirtualMachineRelocateSpec
    $cloneSpec.Location.Host = (Random(Get-VMHost | Where {$_.Name -like "*esxiqa*"}) | get-view).MoRef
    $targetDatastore = ($MapInfo | Where-Object {$_.Name -eq "Hard disk 1"}).NewDataStore
    $cloneSpec.Location.Datastore = (Get-Datastore $targetDatastore | get-view).MoRef
        $cloneSpec.customization = New-Object VMware.Vim.CustomizationSpec
            $cloneSpec.customization.globalIPSettings = New-Object VMware.Vim.CustomizationGlobalIPSettings

            $cloneSpec.customization.identity.guiUnattended = New-Object VMware.Vim.CustomizationGuiUnattended
                $cloneSpec.customization.identity.guiUnattended.autoLogonCount = 0
                $cloneSpec.customization.identity.guiUnattended.password = New-Object VMware.Vim.CustomizationPassword
                    $cloneSpec.customization.identity.guiUnattended.password.plainText = $true
                    $cloneSpec.customization.identity.guiUnattended.password.value = Get-Password -Username "Administrator"
            $cloneSpec.customization.identity.identification = New-Object VMware.Vim.CustomizationIdentification
                $cloneSpec.customization.identity.identification.joinWorkgroup = "WORKGROUP"
#           $spec.customization.identity.licenseFilePrintData = $null
            $cloneSpec.customization.identity.userData = New-Object VMware.Vim.CustomizationUserData
                $cloneSpec.customization.identity.userData.computerName = New-Object VMware.Vim.CustomizationFixedName
                    $cloneSpec.customization.identity.userData.computerName.name = $cloneName
                $cloneSpec.customization.identity.userData.productID = $ProductKey
            $cloneSpec.customization.nicSettingMap = $nicMaparray
                #nicMaparray build above
#           $cloneSpec.customization.options = $null
    $cloneSpec.powerOn = $true

    Get-HardDisk -VM $sourceName | %{
        $disk = New-Object VMware.Vim.VirtualMachineRelocateSpecDiskLocator
        $disk.diskId = $_.ExtensionData.Key #2001,2002,2003,...
        $DiskLabel = $_.ExtensionData.DeviceInfo.Label
        $dsname = ($MapInfo | Where-Object {$_.Name -eq $DiskLabel}).NewDataStore
        $ds = Get-Datastore -Name $dsname
        $disk.datastore = $ds.id
        $cloneSpec.Location.Disk += $disk
    }

    Write-Verbose "Cloning $sourceName"
    try
    {
        $vm.CloneVM( $cloneFolder, $cloneName, $cloneSpec)
        return $true
    }
    catch

        $_.Exception
        return $false
