The Oracle Exalogic Elastic Cloud X2-2 solution includes a set of compute
nodes connected through QDR InfiniBand IO Fabric. In order to virtualize the I/O for these nodes, the Single Root Input Output Virtualization (SR-IOV) has to be turned on. However, ILOM and BIOS updates will reset the settings, which prevents virtualization, and causes some headaches if you're trying to get that virtualization working quickly.
So, we put together a How-To that explains how to enable SR-IOV. You can do it through the Ops Center UI or from the command line; the how-to walks you through both ways of doing it, and gives you a pointer over to the Exalogic section of the Feature Reference guide for more info.
