Efficient Hyper-V VM Status Reporting Script

Monitoring the status of Hyper-V virtual machines is essential for administrators to maintain optimal performance and uptime. In this post, we will share a PowerShell script that retrieves and displays the current state of all Hyper-V virtual machines. This script will help you quickly identify which VMs are running, stopped, or in any other state, enabling effective management of your virtualization environment.
Step 1: Retrieve VM Statuses
This step will gather the status information for all Hyper-V virtual machines on the host.

$VMs = Get-VM
$VMStatusList = @()
foreach ($VM in $VMs) {
    $VMStatusList += [PSCustomObject]@{
        Name   = $VM.Name
        Status = $VM.State
    }
}
$VMStatusList

In this part of the script, we retrieve all virtual machines using the `Get-VM` cmdlet and create a custom object containing the VM name and its current status. The results are stored in an array for easy display.
Step 2: Display VM Statuses
Next, we will format and display the collected VM statuses in a user-friendly manner.

$VMStatusList | Format-Table -AutoSize
Write-Host "Virtual Machine statuses retrieved successfully."

Here, we use the `Format-Table` cmdlet to present the status of each VM in a clear table format, making it easy for administrators to read and analyze the information.
Step 3: Implement Error Handling
To ensure the script runs smoothly and handles potential errors, we will add error handling.

try {
    $VMs = Get-VM
    if ($null -eq $VMs) {
        throw 'No virtual machines found.'
    }
} catch {
    Write-Host 'ERROR: Unable to retrieve VM status. Details: ' $_.Exception.Message
}

In this final part, we implement a `try-catch` block to handle any exceptions when retrieving the VM list. If an error occurs, it outputs a meaningful error message, assisting in troubleshooting.
By utilizing this PowerShell script, administrators can efficiently monitor the status of Hyper-V virtual machines, enhancing overall management capabilities.
