CentOS (Community Enterprise Operating System) is a very popular Linux
distribution based on RedHat Enterprise Linux. The default CentOS distribution
is too bloated for webserver use. This VMware virtual machine image contains a
minimal CentOS-6.4 64-bit guest operating system, enhanced with libraries
typically needed in a server environment. This VMware image enables you to
quickly and easily run Linux on Windows, Mac OS-X or any other x86 based
platforms VMware and VirtualBox (Oracle VM) supports.
