Disable VT-d and SR-IOV in BIOS

Disable VT-d and SR-IOV in BIOS

You must disable Virtualization Technology for Directed I/O (VT-d) in BIOS before you can use Oracle VM. This is necessary because input/output memory management unit (I/O MMU) is not supported in Oracle VM 3.2. You must also disable Single Root I/O Virtualization (SR-IOV) in BIOS before you can use Oracle VM.

To disable the VT-d setting in BIOS, perform the following steps:

1. Reset or power on the server.
   For example to reset the server:
   • From the local server, press the Power button (approximately 1 second) on the front panel of the server to power off the server, then press the Power button again to power on the server.
   • From the Oracle ILOM web interface, select Host Management > Power Control, then select Reset from the Select Action list box.
   • From the Oracle ILOM CLI, type: reset /System
   The BIOS screen appears.
