Run the emulation with:

|

qemu-system-i386 -M pc -kernel output/images/bzImage -drive file=output/images/rootfs.ext2,if=ide,format=raw -append root=/dev/sda -net nic,model=rtl8139 -net user

qemu-system-i386 -M pc -kernel output/images/bzImage -drive file=output/images/rootfs.ext2,if=virtio,format=raw -append root=/dev/vda -net nic,model=virtio -net user

The login prompt will appear in the graphical window.
