You are in luck.

The Debian installer includes special options to run it
completely non-interactively, it involves a technique
called "preseeding" described in the Debian installation
guide on www.debian.org.

Preseeding requires some special steps to pass your
desired configuration to it, this is in the guide too.

More generally, there are two ways to do a non-interactive
OS installation in a qemu VM:

A) If the OS installer has a mechanism/procedure for
  non-interactive installation on physical machine, that
  technique should work under qemu too.  Preseeding the
  Debian installer is one example of this.

B) Using a script to put the various parts of the OS
  into a disk image, then convert that disk image to a
  qemu virtual disk (using the qemu-img command) and
  finally just booting the VM from that disk.


Enjoy
