Script to set memory reservation on all vm's

[crawfordm]

I am trying to write a script that will set a memory reservation on all vm's to what the vm memory is.  This way all swap files will be 0.

I am not sure of $_.MemoryMB will give me the correct setting.

$vm = Get-VM

foreach ($vm_single in $vm)

    {Get-VMResourceConfiguration | Set-VMResourceConfiguration -MemReservationMB $_.MemoryMB

    }

Get-VMResourceConfiguration -VM $vm_Single | Select -ExpandProperty DiskResourceConfiguration

Thanks

Hi Marc,

you are correct about the MemoryMB property.Only in your case you should use $vm_single.MemoryMB. However the Set-VMResourceConfiguration -MemReservationMB parameter is obsolete. Use MemReservationGB instead:

foreach ($vm in (Get-VM))
{
  Get-VMResourceConfiguration |
  Set-VMResourceConfiguration -MemReservationGB $vm.MemoryGB
}
