   $ qemu-img create /tmp/disk.img 10G && \
      /usr/bin/qemu-system-x86_64 -m 1024 -display sdl -vga std \
      -enable-kvm -drive file=/tmp/disk.img \
      -cdrom ~/iso/ubuntu/precise-desktop-amd64.iso
  2. Press 'space' to display the boot menu
  3. Press F4, select OEM installation then validate with 'Enter'
  4. Select 'Install Ubuntu' and 'Enter'
  5. Wait until installation starts
