Get Virtual Machine Inventory from a Hyper-V Failover Cluster using PowerShell

A colleague was asking around for a PowerShell script that would fetch some inventory data for VMs on a Hyper-V cluster the other day. Not knowing too much about Hyper-V and having only ever briefly looked at what was out there in terms of PowerShell cmdlets for managing Hyper-V, I decided to dive in tonight after I got home.


Here is a function that will fetch Inventory data for all VMs in a specified Failover Cluster. This is what it fetches:

  • VM Name
  • VM CPU Count
  • VM CPU Socket Count
  • VM Memory configuration
  • VM State (Up or Down)
  • Cluster Name the VM resides on
  • Hyper-V Host name the VM resides on
  • Network Virtual Switch Name
  • NIC Mac Address
  • Total VHD file size in MB
  • Total VHD Count


Being a function, you can pipe in the name of the cluster you want, for example Get-Cluster | Get-HyperVInventory. Or you could do Get-HyperVInventory -ClusterName “ExampleClusterName”. You could also send it to an HTML Report by piping it to “ConvertTo-HTML | Out-File example.html”

Download here, or copy it out from the script block below:

# Requires: Imported HyperV PowerShell module (http://pshyperv.codeplex.com/releases/view/62842)
# Requires: Import-Module FailoverClusters
# Requires: Running PowerShell as Administrator in order to properly import the above modules

function Get-HyperVInventory {
Fetches Hyper-V VM Inventory from a specified Hyper-V Failover cluster

Fetches Hyper-V VM Inventory from a specified Hyper-V Failover cluster

.PARAMETER ClusterName
The Name of the Hyper-V Failover Cluster to inspect

PS F:\> Get-HyperVInventory -ClusterName "dev-cluster1"

PS F:\> Get-Cluster | Get-HyperVInventory

[Parameter(Position=0,Mandatory=$true,HelpMessage="Name of the Cluster to fetch inventory from",

process {

$Report = @()

$Cluster = Get-Cluster -Name $ClusterName
$HVHosts = $Cluster | Get-ClusterNode

foreach ($HVHost in $HVHosts) {
$VMs = Get-VM -Server $HVHost
foreach ($VM in $VMs) {
[long]$TotalVHDSize = 0
$VHDCount = 0
$VMName = $VM.VMElementName
$VMMemory = $VM | Get-VMMemory
$CPUCount = $VM | Get-VMCPUCount
$NetSwitch = $VM | Get-VMNIC
$NetMacAdd = $VM | Get-VMNIC
# VM Disk Info
$VHDDisks = $VM | Get-VMDisk | Where { $_.DiskName -like "Hard Disk Image" }
foreach ($disk in $VHDDisks) {
$VHDInfo = Get-VHDInfo -VHDPaths $disk.DiskImage
$TotalVHDSize = $TotalVHDSize + $VHDInfo.FileSize
$VHDCount += 1
$TotalVHDSize = $TotalVHDSize/1024/1024
$row = New-Object -Type PSObject -Property @{
Cluster = $Cluster.Name
VMName = $VMName
VMMemory = $VMMemory.VirtualQuantity
CPUCount = $CPUCount.VirtualQuantity
CPUSocketCount = $CPUCount.SocketCount
NetSwitch = $NetSwitch.SwitchName
NetMACAdd = $NetMacAdd.Address
HostName = $HVHost.Name
VMState = $HVHost.State
TotalVMDiskSizeMB = $TotalVHDSize
TotalVMDiskCount = $VHDCount
} ## end New-Object
$Report += $row
return $Report



Example use cases – load the function into your PowerShell session, or place it in your $profile for easy access in future, and run the following:

# Example 1
Get-HyperVInventory -ClusterName "mycluster1"
# Example 2
Get-Cluster | Get-HyperVInventory
# Example 3
Get-HyperVInventory -ClusterName "mycluster1" | ConvertTo-HTML | Out-File C:\Report.html


The function includes help text and examples, so you can also issue the normal “Get-Help Get-HyperVInventory” or “Get-Help Get-HyperVInventory -Examples”. It is by no means perfect and could do with some improvements, for example if there is more than one Virtual Switch Network associated with a VM these would be listed in a row multiple times for each. Feel free to suggest any improvements or changes in the comments.

    Interesting script, but this is not working, after importing all modules and running the command, I can only receive “invalid Class” errors and an error in the vhdpaths argument… is there any other indication to get run this script?
    Thanks in advanced.

    Hey I am a fan of your posts, i just want to point you to my blog and a couple of powershell scripts I have created them from a hodge podge of sites and just trial and error, not a programer just old school administrator running datacenter 2012 with hyper-v 3.0



    I was hoping you could improve them or post them for others to use, my blog is not all that popular but I want to share.

    Hey James,

    Those are nice posts – good job there. Keep it up, blogging is fun and can be rewarding if you keep at it!

    I created a new project called pshvm.codeplex.com and it is the first all powershell script free hyper-v manager that includes a replacement for vmconnect and mstsc. It is meant to be run from the console. I included my reporting.codeplex.com project so now you can manage and report for free.
