Get Hyper-V guest serial number with PowerShell

Retrieve the Hyper-V virtual machine’s serial number with PowerShell. Sometimes you need to have the serial number of a Hyper-V virtual machine (VM, or guest). We, for instance, use this serial number in our automatic, unattended deployment of the guest operating system. But then you need to know how to find this serial number…

And that’s where PowerShell comes in. The following PowerShell snippets print out all virtual machines on a Hyper-V server, with the Hyper-V serial numbers (a.k.a BIOSSerialNumber) for the VM’s:

Get-WmiObject -ComputerName hyper-v_server -Namespace ` 
root\virtualization\v2 -class Msvm_VirtualSystemSettingData `
| select elementname, BIOSSerialNumber


To use this PowerShell snippet on the PowerShell command line, remove the backticks (`) and place the command on one line.

The output is of the above Get-WmiObject command is:

elementname  BIOSSerialNumber
-----------  ----------------
hyperv-vm-01 1111-2222-3333-4444-5555-6666-77
hyperv-vm-02 1112-2223-3334-4445-5556-6667-77

This PowerShell code utilizes the Get-WmiObject Cmdlet.

System administrators will likely rely heavily on Get-WmiObject to help them with their routine management tasks. Because at this time there are only a few cmdlets designed for carrying out system administration tasks (Get-Process, Get-Service, and Get-EventLog).

You can see Get-Service in action when monitoring Windows services with PowerShell.

The Hyper-V virtual machine’s instance ID (GUID) is retrieved requesting InstanceID:

Get-WmiObject -ComputerName hyper-v_server -Namespace ` 
root\virtualization\v2 -class Msvm_VirtualSystemSettingData `
| select elementname, InstanceID
