Comment 2 for bug 1360151

Tried with Icehouse and it's also incorrect.

$ glance image-create ....--copy-from https://cloud-images.ubuntu.com/trusty/current/trusty-server-cloudimg-amd64-disk1.img

- master

  it = utils.chunkreadable(image_file, 10485760)

  "it" will be a chunk of 65536 bytes.

- icehouse

  it = utils.chunkreadable(image_file, 10485760)

  "it" will be a chunk of 16777216 bytes.

Both should be a chunk of 10485760 bytes.
