Can you attach the AVC messages from audit log.

Try policy on people.redhat.com/dwalsh/SELinux/RHEL6
This is a little too cryptic for me. I went to this url and since my system is i386 architecture, I went to the i686 directory. There I find a number of RPMs and a number that start with policy. I assume I can add this to my yum.repo over whatever I normally get for Centos, but what do I install or update?
You want the selinux-policy packes from the noarch directory.
