Intel Ethernet X520 10GbE Dual Port KX4 Mezz User Manual page 104

The ixgbevf driver requires the ixgbe driver, version 2.0 or later. The ixgbevf driver supports virtual functions generated
by the ixgbe driver with a max_vfs value of 1 or greater. For more information on the max_vfs parameter refer to the sec-
tion on the ixgbe driver.
The guest OS loading the ixgbevf driver must support MSI-X interrupts.
This driver is only supported as a loadable module at this time. Intel is not supplying patches against the kernel source
to allow for static linking of the driver. For questions related to hardware requirements, refer to the documentation sup-
plied with your Intel 10GbE adapter. All hardware requirements listed apply to use with Linux.
Instructions on updating ethtool can be found in the section

To verify your adapter is supported, find the board ID number on the adapter. Look for a label that has a barcode and a
number in the format 123456-001 (six digits hyphen three digits). Match this to the list of numbers above.

Building and Installation
To enable SR-IOV on your system:
1. Ensure both Virtualization and SR-IOV are enabled in the BIOS.
2. Install the Linux operating system. You can verify that the kvm driver is loaded by typing: lsmod | grep -i
kvm
3. Load the Linux Base Driver using the modprobe command: modprobe ixgbe option max_vfs=xx,yy
xx and yy are the number of virtual functions you want to create. You must specify a number for each port with
each parameter separated by a comma. For example, xx is the number of virtual functions for port 1; and yy, for
port 2. You can create up to 63 functions per port.
4. Compile and install the ixgbevf driver for SR-IOV. This is loaded against the virtual functions created.
Instructions to configure virtual functions are provided in the Technical Briefs listed below. It should be noted that the
information contained in these documents references typical configurations. Consult your operating system vendor for
the latest information.
