I am not certain if I understand your inquiry entirely correctly but if you refer to the product configuration it depends on whether you have set configurable options. If yes, default product details will appear upon order placing but a customer will be able to change them at will. Otherwise, the particulars of a virtual machine will match those set in the Module Settings section.
