One of the principles of good security practice is to keep all software versions and patches up-to-date. Throughout this document, we assume that you are installing the necessary security patches and package updates on the Oracle Linux host running Oracle VM Manager, as well as the Oracle VM Servers in your environment. It is recommended that you:
Register your Oracle VM Manager host with the Unbreakable Linux Network (ULN). See Unbreakable Linux Network for information on using ULN.
For x86-based Oracle VM Servers, set up a local YUM repository and retrieve the updates from the Oracle VM channel on ULN. See the Yum Repository Setup article on OTN. As of Oracle VM Release 3.3, you can upgrade SPARC-based servers using an IPS server update repository. See the Oracle VM Manager User's Guide for information on setting up these server update repositories.
Create server update repositories for your Oracle VM Servers in Oracle VM Manager. See the Oracle VM Manager User's Guide for more information on creating server update repositories.
