Quoting Stevens, Weston (wstevens@eecs.wsu.edu):
> I run Ubuntu 10.04 LTS and have qemu 0.12.3. For a class project, we are building our own pseudo-linux operating system, so we have our own kernel AND user processes that we built, and we run this OS from a virtual floppy disk. So we don't borrow anything from the Ubuntu host OS like the login, init, sh, etc process images, just the ones we wrote ourselves that exist on the floppy's file system.

IIUC you'll want to use the -serial option.  I.e. 

	kvm -serial stdio ... image.img

Will give you ttyS0 in the terminal from which you called kvm.  Or, you can
do

	kvm -serial tcp:localhost:2222,server ... image.img

and then

	telnet localhost 2222

from another terminal, to get serial port redirected through telnet.
