Giving the following commands which works fine and the OS starts normally

qemu-system-x86_64 -m 2G  --enable-kvm example-of-os.qcow2

Is there a way, a command or a file to consult, to know what default options have been used for what has not been explicitly defined: harddrive, networking, usb, keyboard... ?

I am not talking about documentation, but result from the currently running VM.

For example, firstly you would start with -serial mon:stdio on the command line, so as to have the built-in monitor available. Then you activate it with ^Ac (control-A c), which brings the qemu prompt. There you use the info command.
