[CentOS-devel] How to run cloud image for 6.5?

Hi,

On my way to run centOS 6.5 on OpenStack I found the cloud images at

http://cloud.centos.org/centos/6.5/devel/

and while the corresponding image for centOS 7 seems to work fine, I still need the older version for some legacy application, but I cannot find a way to run the images provided in that directory.

Especially I'm looking at http://cloud.centos.org/centos/6.5/devel/CentOS-6.5-x86_64-GA-03.img.gz, but as well uploading the unzppied .img file to OpenStack as image and trying to boot an instance with it, as well as runinng it locally with

qemu-system-i386 CentOS-6.5-x86_64-GA-03.img

both give me the same error - "Boot failed - not a bootable disk"

Any idea what I could be doing wrong / should be doing to get it booting?

Thanks, Henning
