I'm interested in being able to spawn centos servers on AWS that already come pre-configured with packages/services/files that I have installed/configured on the image. I'm at http://cloud.centos.org/centos/7/images/ and I'm seeing that there are a number of different file extensions, including .raw, .qcow, .qcow2 etc.
What are the differences between these file types?
This is the first time i've run into an issue that appear to be critical in nature, but the peculiar thing is that I have downloaded so many of these Centos 7 images (from everything iso's to dozens of mirrors), and this is a constant (when I get an image that will install)
Basic Virtual Box install, host is a windows 64 bit
Here's the first image, when I try to use yum for anything
