It is not obvious what the result of this would be. What hostname will it have? How will the disk be partitioned? What packages will be installed? What timezone will be set? What keyboard layout will be set? And so on.
virt-install can be given all of those parameters as arguments[0], too; parent just didn't post an obnoxiously large shell line to demonstrate.
