About creating virtual machines in parallel

[YanSi]

Use this script to create virtual machines, which are created one by one in order.
How can I modify it to support parallel creation of virtual machines based on the following script?

# Starting Script
Write-Host ("Starting Script: {0}" -f (Get-Date -format 'u'))
$startTime = Get-Date

######################## SECTION A
# Make errors to be terminating. Otherwise some won't be caught.
$ErrorActionPreference = "Stop"
Try {
# Specify the location of the CSV file.
$CSVFile = "C:\Deploy-Linux-VMs-1NIC.csv"
$CSVVm = Import-Csv $CSVFile
ForEach ($CSVRow in $CSVVm) {
######################## SECTION B
# Verifying that the input is correct and that the VM name is not already in use.
$VmTemplate = Get-Template $CSVRow.TEMPLATE
$VmPortgroup1 = Get-VirtualPortGroup -Name $CSVRow.PORTGROUP1
$VmDatastore = Get-Datastore $CSVRow.DATASTORE
$VmCluster = Get-Cluster $CSVRow.CLUSTER | Where DrsAutomationLevel -ne "manual"
if (Get-VM $CSVRow.VMName -ErrorAction SilentlyContinue) {Throw "A virtual machine with name $($CSVRow.VMNAME) already exists"}
######################## SECTION C
# Cloning existing custom specs to a temporary one
$CustomSpec = New-OSCustomizationSpec -OSCustomizationSpec "rhel7-custspec" -Name (New-Guid | Select -ExpandProperty guid) -Type NonPersistent
######################## SECTION D
# Configuring the network settings in the custom specs
$CustomSpec | Get-OSCustomizationNicMapping | Set-OSCustomizationNicMapping -IpMode UseStaticIP -IpAddress $CSVRow.IP1 -SubnetMask $CSVRow.MASK1 -DefaultGateway $CSVRow.GATEWAY1
######################## SECTION E
# Deploying the VM
$NewVM = New-VM -Template $VmTemplate -OSCustomizationSpec $CustomSpec -ResourcePool $VmCluster -Datastore $VmDatastore -Name $CSVRow.VMNAME
######################## SECTION F
# Connecting the correct PortGroup
$NewVM | Get-NetworkAdapter | Set-NetworkAdapter -StartConnected $true -Confirm:$false -NetworkName $CSVRow.PORTGROUP1
######################## SECTION G
# Starting the VM
$NewVM | Start-VM
}
} CATCH {
######################## SECTION H
Write-Error $_.Exception -ErrorAction stop
}

# End Script
$endTime = Get-Date
$totalSeconds = "{0:N4}" -f ($endTime - $startTime).TotalSeconds
Write-Host "All Jobs Finished in $totalSeconds Seconds"

There are a couple of options.
You can use Start-Job, to run several jobs in the background in parallel.

When you are on PowerShell 7 and using at least PowerCLI 12.2, you can use Foreach -Parallel.

[YanSi]

I use the -Parallel parameter and the prompt is as follows:

ParserError:
Line |
5 | ForEach -Parallel($CSVRow in $CSVVm) {
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| The foreach '-parallel' parameter is reserved for future use.

You are not using it correctly, that should be

$CSVVm | ForEach-Object -Parallel {
   # your code
}

[YanSi]

I use “$CSVVm | ForEach-Object -Parallel”

($CSVRow in $CSVVm) will be invalid

Variables like "$CSVRow.DATASTORE" ……etc, will not be quoted

"ForEach ($CSVRow in $CSVVm)" can refer to $CSVRow

[LucD]

Inside the codeblock you use $_.DATASTORE

[YanSi]

I do not know where the problem

Thank you for quickly replying to me and helping me.

As per the error, you have not connected to vCenter

That error can have many causes.
Does it work when you set your ExecutionPolicy temporarily to Unrestricted?

Another test you can do is try to import with the full path

Import-Module C:\Users\Administrator\Documents\PowerShell\Modules\VMware.VimAutomation.Core\12.3.0.17839688\VMware.VimAutomation.Core.psd1

Ultimately you try to do a full reinstall.
First delete all PowerCLI modules from the File Manager, then do the Install-Module.

I think the message is clear 

Could not find VMHost with name 'VM Network'.

There is an error in your input to the cmdlet

[LucD]

You might want to have a look at New Release – VMware PowerCLI 12.2

The Foreach-Object -parallel{} is now supported section contains an example.
