You cannot set a minimum below the current template value. Changes apply to new VMs, they are not retroactive. However, if users edit existing VMs that already had out-of-range values, the platform displays a warning but does not enforce the range. Changes can affect recommended hardware profiles on the Advanced tab, so you may need to review them. Users with the Override VM constraints privilege can enter values outside this range
