    A place people sometimes trip with SELinux is the labeling of files. SELinux requires files to be labeled correctly in order to function. Discretionary Access Control has the same requirement in that file must have the correct permissions and ownership. If a file does not have the correct permissions it can not be read, written or executed. Similarly if a file is not labeled correctly SELinux will prevent read/write/execute as well as many other permissions and transitions. Are you a Xen user? If so this article will show you steps to increase your images security by using SELinux.
