Setting Up SR-IOV
Note: Currently, SR-IOV is supported only in non-multichannel setups.
Prerequisites
To set up SR-IOV on your system, you need the following:

A server/blade with an SR-IOV-capable motherboard BIOS.
Note: Configuration mechanisms for parameters such as MAC address, VLAN
and QoS for VF are supported in RHEL 6 and above, and SLES 11 and
above distributions.

OneConnect OCx11102-xT UCNA, or later adapter versions, or LPe16202 CFA
in FCoE+NIC mode.

If a KVM hypervisor is installed, it must contain the qemu-kvm packages.
Depending on your system, perform one or more of the following tasks to set up your
BIOS. For more information, see the manufacturer’s instructions for your system.

Enable SR-IOV in the system BIOS. This supports SR-IOV functionality.

Enable Intel Virtualization Technology support for Direct I/O VT-d.
Procedure
You can use the PXESelect utility or the UEFI (HII) utility to set up SR-IOV.
To enable and configure SR-IOV in the OneConnect firmware using either the
UEFIBoot utility or the PXESelect utility, see the Boot for NIC, iSCSI, FCoE, and RoCE
Protocols User Manual.
1. Install the required Linux operating system that serves as a hypervisor.
2. Update the /boot/grub/menu.lst file to include the following command line load
parameter for the Linux kernel:
intel_iommu=on
3. Install the appropriate version of the Emulex Ethernet driver that supports SR-IOV
for the operating system version that you are using.
4. Reboot the server for the new changes to become operational.
5. Use the “lspci -vvv” output command to check if SR-IOV is properly enabled:
lspci -vvv
This command returns an SR-IOV capability section for each Ethernet PF. The
Initial VFs and Total VFs should be non-zero. Make a note of the lspci command
output in the hypervisor. This output is needed in step 10 on page 842. Specifically
make note of the pci-id of the VFs that have been created.
Example of the SR-IOV capabilities section output of the PF with SR-IOV enabled:
Capabilities: [180] Single Root I/O Virtualization (SR-IOV)
IOVCap: Migration-, Interrupt Message Number: 000
IOVCtl: Enable- Migration- Interrupt- MSE- ARIHierarchy-
