“`powershell
Get-VM | Select-Object Name, State, ProcessorCount, MemoryAssigned | Export-CSV -Path “C:VM_Details.csv” -NoTypeInformation
“`
This command saves the selected virtual machine details to a CSV file in the C: directory.
Step 6: Automate with PowerShell Script
Create a new PowerShell script (e.g., “Get-VM_Details.ps1”) using your preferred text editor or PowerShell ISE. Include the following script to automate the process of collecting and managing virtual machine details:
“`powershell
# Import Hyper-V module
Import-Module Hyper-V
# Filter VM details
$vmDetails = Get-VM | Select-Object Name, State, ProcessorCount, MemoryAssigned
# Export VM details to CSV
$vmDetails | Export-CSV -Path “C:VM_Details.csv” -NoTypeInformation
# Display VM details in the console
$vmDetails
“`
Save the script and run it on-demand or schedule it as a task using Windows Task Scheduler.
By following these steps, you can automate the process of collecting and managing virtual machine details within Hyper-V using PowerShell scripting.
