Server BIOS Configuration
SR-IOV requires support in the server chipset beyond standard virtualization
technologies, including operating system control of PCIe and interrupt remapping. The
server may have BIOS options to control SR-IOV, and typically these are disabled by
default. The following may need modification in your system BIOS during boot:

Enable “Virtualization”, such as Intel VT-x or AMD-V. This is required for any
virtual machine.

Explicitly enable SR-IOV in the system BIOS. The specific name for this option
varies between vendors. For instance it may be called Intel VT-d (Virtualization
Technology for Direct I/O), AMD-Vi (AMD I/O Virtualization Technology), or
IOMMU.
Emulex PXESelect Configuration for SR-IOV
The Emulex OCe11000 family of adapters requires enabling firmware support for
SR-IOV within the Emulex PXESelect BIOS. See the
Boot for NIC, iSCSI, FCoE, and
RoCE Protocols User Manual for more information.
To enable firmware support in the PXESelect BIOS:
1. Press <Ctrl+ P> during the Emulex PXE Select splash screen as the server boots. A
screen appears showing global options.
2. Set the following options to use SR-IOV:
