There are quite a few clicks to add a virtual machine from a datastore to inventory. If you were to consolidate an environment and had to add multiple virtual machines this would be quite a manual task. Easier solution? Script it! The below script makes scanning a datastore and registering all virtual machines with vCenter a breeze.

You must have VMware PowerCLI installed in order to have the cmdlets required for PowerShell to run the script.

Add VMX (Virtual Machines) to Inventory from a Datastore:

#####################################################################
# Load VMware Plugins and vCenter Connect #
#####################################################################

Add-PSSnapin vmware.vimautomation.core

connect-viserver -server ENTER VCENTER FQDN HERE
#####################################################################
# Add .VMX (Virtual Machines) to Inventory from Datastore #
#####################################################################

# Variables: Update these to the match the environment
$Cluster = "ENTER CLUSTER NAME HERE"
$Datastore = "ENTER DATASTORE NAME HERE"
$VMFolder = "ENTER FOLDER NAME HERE"
$ESXHost = Get-Cluster $Cluster | Get-VMHost | select -First 1

foreach($Datastore in $Datastore) {
# Searches for .VMX Files in datastore variable
$ds = Get-Datastore -Name $Datastore | %{Get-View $_.Id}
$SearchSpec = New-Object VMware.Vim.HostDatastoreBrowserSearchSpec
$SearchSpec.matchpattern = "*.vmx"
$dsBrowser = Get-View $ds.browser
$DatastorePath = "[" + $ds.Summary.Name + "]"

# Find all .VMX file paths in Datastore variable and filters out .snapshot
$SearchResult = $dsBrowser.SearchDatastoreSubFolders($DatastorePath, $SearchSpec) | where {$_.FolderPath -notmatch ".snapshot"} | %{$_.FolderPath + ($_.File | select Path).Path}

# Register all .VMX files with vCenter
foreach($VMXFile in $SearchResult) {
New-VM -VMFilePath $VMXFile -VMHost $ESXHost -Location $VMFolder -RunAsync
}
}

Let’s see it in action!
