The server supports several operating systems. Therefore, you do not have to use the preinstalled version of the Oracle VM Server software on your server. If you want to install a fresh or newer version of the Oracle VM Server software or a different operating system such as Oracle Linux or other Linux, Oracle Solaris, Windows Server, or VMware ESXi, you can do so, provided it is a supported version. For a list of supported operating systems, refer to the Oracle Server X5-2L Product Notes at http://www.oracle.com/goto/x5-2l/docs.
