Comment 5 for bug 619974

I mentioned this to Andreas yesterday, but just to have text in this bug:
- Each "uec image tarball" is a tarfile with files explained at http://bazaar.launchpad.net/~ubuntu-on-ec2/vmbuilder/automated-ec2-builds/annotate/head%3A/README.files
- to boot one of these in test drive:
  # the .img files are largely sparse, so using 'tar -S' is quite desirable.
  tar -Sxvzf tarball.tar.gz
  bname=$(echo *.img) && bname=${bname%.img}
  # It is not necessary to use a qcow backing image, but useful to keep the
  # .img file pristine
  qemu-img create -f qcow2 -b ${bname}.img.dist disk.img
  kvm -boot a -fda ${name}-floppy -drive file=disk.img,if=virtio
