What Are the common commands that you use when you clone a virtual machine and specify the settings?

Hi again all,

I am new to the virtualization world, and am learning new things everyday.  Today i came across cloning and how to clone virtual Machine and how to create a template and all.

My simple question (out of curiosity)  is for the people with real life experience, what commands do you usually run in a new cloned machine under the run once configuration option ? And suppose am using a windows, when and where are the commands being run?

Thanks in advance!
