PowerCLI: Retrieve VMs where CPU or Memory Reservation has been enabled

Posted on April 24, 2014 by Dean Grant

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 }} 
    }
