Bug Description

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.
