Thanks Avadh for looking into this. I went through the mialing list archives and turns out that I was attempting to create checkpoint with a raw image format. I tried with qcow2 and was able to create the checkpoints for bzip2. Just need to figure out now how I can run a couple of checkpoints with and without the run_bench.py script.
