On the guest. When you use -nographic, you get a (vritual) pc without
a monitor, but with a serial port. If your Fedora is not set up to
have a login on the serial port, you will see nothing when you connect
a serial cable to the port. You can have login prompts both on serial
and on screen.

You could also ssh into the guest instead.
