PowerShell is King – Find VM Configuration files (.vmcx) that have not been imported/registered

Posted by Mikael Nystrom on November 9, 2016

Sometime you need to move a large number of VMs, or you need to recover from a broken hyper-v host, or similar. If you have a few VM’s, that will be easy, but if you have many you will most likely use PowerShell to import the VM’s. That works perfectly fine, but you have a few VM’s that did weren’t imported correctly you will end in a state when you ask your self –Which VM’s are imported and which ones are not?

(You can download the script from GitHub: https://github.com/DeploymentBunny/Files/tree/master/Tools/Get-VIAUnimportedvmcxFiles )

Find the not yet imported VM configurations

That will of course be done using PowerShell, and here is the function that I use

    #>    
    [CmdletBinding(SupportsShouldProcess=$true)]
    
    Param(
    [string]$Folder
    )

    if((Test-Path -Path $Folder) -ne $true){
        Write-Warning "I'm sorry, that folder does not exist"
        Break
    }

    $VMsIDs = (Get-VM).VMId
    $VMConfigs = (Get-ChildItem -Path $Folder -Filter *.vmcx -Recurse).BaseName

    $obj = Compare-Object -ReferenceObject $VMsIDs -DifferenceObject $VMConfigs

    $Configs = foreach($Item in ($obj.InputObject)){
        $Items = Get-ChildItem -Path $Folder -Recurse -File -Filter *.vmcx  | Where-Object -Property Basename -Like -Value "*$Item" 
        $Items | Where-Object -Property FullName -NotLike -Value "*Snapshots*"
        }
    Return $Configs.FullName
}
