I’ve had complaints from customers that the compressed qcow image on cloud images for CentOS 7 is corrupt - failing with an XFS panic. 


The raw and the uncompressed qcow2 image appear fine. 

If I compress the raw image to a qcow2c with

qemu-img convert -p -c -O qcow2 CentOS-7-x86_64-GenericCloud-20150628_01.raw CentOS-7-x86_64-GenericCloud-20150628_01.qcow2c

then I get the same size as the downloaded file but with binary differences.

Could somebody take a look?
