>From the man page:

           Normally, QEMU uses SDL to display the VGA output. With this
           option, you can totally disable graphical output so that QEMU is a
           simple command line application. The emulated serial port is redi-
           rected on the console. Therefore, you can still use QEMU to debug a
           Linux kernel with a serial console.

But, I do not think you can run most (any?) installers like this,
without the serial console being redirected to _something_, and
if you're doing this over ssh, that default something may not be
immediately visible.

The -vnc option looks like a win, maybe.

Per above (not quoted) -cdrom /dev/acd0 might not work if
the permissions are not set correctly on /dev/acd0.  It is usually
easier under qemu to use the downloaded image instead of
burning to CD and all that.  Or use dd to make a new image
if you've already deleted it.
