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.
