You can add or configure most virtual machine properties during the virtual machine creation process or after you create the virtual machine and install the guest operating system.

You configure the virtual machine hardware and can change nearly every characteristic that you selected when you created the virtual machine. You can view the existing hardware configuration and add or remove hardware. You can configure CPUs, memory, and disks.

Not all hardware devices are available to every virtual machine. The host that the virtual machine runs on and the guest operating system must support devices that you add or configurations that you make.
