x86 doesn't use the serial port for console by default, so you're making
things quite a bit more difficult that way.  Typically you'll want to
provide a disk image (the -hda option is the easiest way to do this), a
display (-vga std -vnc :0 is again easiest), and probably something to
install from (-cdrom <image.iso>).  You can also add a -boot d to get it
to choose the cdrom the first time for install.  Thanks,
