You can configure virtual machines at any time—during the virtual machine creation process or after you create the virtual machine and install the guest operating system.

You can configure virtual machines using two tools in the vSphere Client: the Virtual Machine Properties editor and the Add Hardware wizard. These dialog boxes also allow you to control advanced virtual machine configuration options. You can also upgrade the virtual hardware of a virtual machine or convert virtual disks from thin to thick using these dialog boxes.

You must have sufficient permission to perform virtual machine configuration tasks.
