The below script block will retrieve VMs where either or both CPU and Memory reservation has been configured and return the value by using the Get-VM cmdlet and retriving the value of both the ‘ExtensionData.ResourceConfig.CpuAllocation.Reservation’ and ‘ExtensionData.ResourceConfig.MemoryAllocation.Reservation’ properties.

$VMs = Get-VM | Where-Object {$_.ExtensionData.ResourceConfig.MemoryAllocation.Reservation -ne "0" -or $_.ExtensionData.ResourceConfig.CpuAllocation.Reservation -ne "0"}
ForEach ($VM in $VMs)
    { 
    "" | Select @{N="Name";E={$VM.Name}},
    @{N="CPU Reservation";E={$VM.ExtensionData.ResourceConfig.CpuAllocation.Reservation}},
    @{N="Memory Reservation";E={$VM.ExtensionData.ResourceConfig.MemoryAllocation.Reservation }} 
    }
