Retrieving a VM Snapshot path from vCenter using Powershell

Sometime, retrieving the path of a VMware VM's Snapshot can prove useful.

As we've had to automate the deployment of some VMware Horizon Pools using Powershell, the cmdlet Add-AutomaticLinkedCLonePool was asking for a Snapshot path as an input with the "ParentSnapshotPath" parameter.

So here's the function that answered this need!

 #Requires -Version 3.0
Function Get-VMSnapshotPath {
<#
    .SYNOPSIS
            This function will return a VM's Snapshot path
    .DESCRIPTION
            This function will return a VM's Snapshot path
    .PARAMETER  Snapshot
            Specifies a VM Snapshot
    .EXAMPLE
            Get-Snapshot -VM (Get-VM "Master") -Name "BaseSnapshot" | Get-VMSnapshotPath
            /BaseSnapshot
    .EXAMPLE
            Get-Snapshot -VM (Get-VM "Master") -Name "SecondSnapshot" | Get-VMSnapshotPath
            /BaseSnapshot/SecondSnapshot
    .EXAMPLE
            (Get-VM "Master"), (Get-VM "MasterVDI") | Get-Snapshot | Get-VMSnapshotPath
            /BaseSnapshot
            /BaseSnapshot/SecondSnapshot
            /VDIBaseSnapshot

                $Path = "/" + $VMo.Name + $Path
                $VMo = $VMo.ParentSnapshot
            }
            $Path
        }
    }
    END {
    }
