Public bug reported:
When writing config drive, dd by default uses 512B as the block size. It
costs more than 3mins to write the 64M config drive. It's longer than
expected: Some health checking(fuel's heat checking) on XenServer may
failed due to timeout. So we need improve the performance via specifying
a bigger block size with dd.
