I want to know about the virtualization that are used in the Red Hat Enterprise Linux 6. Also I am very eager to know about the security with SSSD in RHEL 6. Since, I am not an expert in Red Hat Enterprise Linux 6, any other information related to it would be helpful. I thought to post here, because you guys explain in simple and better language. I am expecting that someone from your side will provide some information to me sooner.
