If you have upgraded your Oracle VM Servers from a 3.2 release and have added a transitional Yum repository for the purpose of performing the upgrade, as described in Section 5.4.1.3, “Configuring the Yum Repositories within Oracle VM Manager”, it is important that you disable or remove this repository in Oracle VM Manager if you have finished your server upgrades. If this repository remains enabled in Oracle VM Manager, you may have trouble updating Oracle VM Servers across future errata releases. See Server Update Groups in the Oracle VM Manager User's Guide for more information.
