function Get-CVVirtualMachine {
<#
.SYNOPSIS
    Method to retrieve the list of virtual machines in the CommCell.
 
.DESCRIPTION
    This method is implemented with Powershell paging support.
    Method to retrieve the list of virtual machines in the CommCell.
    Output can be filtered by Protected/Unprotected status, active subclients of a client, and virtual machine Name.
     
.PARAMETER Name
    Filter output to virtual machine Name.
 
.PARAMETER ClientName
    Filter output by active subclients of ClientName.
 
.PARAMETER ClientId
    Filter output by active subclients of ClientId.
 
.PARAMETER ClientObject
    Filter output by active subclients of ClientObject.
 
.PARAMETER Id
    Specify Id representing virtual machine GUID.
 
.PARAMETER Protected
    Filter output by Protected virtual machines.
 
.PARAMETER UnProtected
    Filter output by UnProtected virtual machines.
 
.PARAMETER First
    Get list of virtual machines with paging support -First 20 (20 per page).
 
.PARAMETER Skip
    Get list of virtual machines with paging support -First 20 -Skip 5 (20 per page, skip first 5 pages).
 
.PARAMETER IncludeTotalCount
    Include total count of result record set.
