Suppose you're an organization that deals with server virtualization and server leasing stuff. You're going to rent cloud computing instances and dedicated servers to customers. You will be using mainly Xen but will also use KVM if customers request it. What would you use on your dom0s (host machines)? 1. Red Hat Enterprise Linux Latest version 2. Centos latest version 3. Fedora latest version 4. Ubuntu Server LTS 5. Ubuntu Server Latest version. Please justify your choice, don't say something like: "Centos, because it is an enterprise server!" or "Red Hat, because it is paid". This doesn't mean anything. Give a good reason for choosing an OS over another.
