Note PCI-SIG SR-IOV requires support from the operating system and hardware platform. Some systems support SR-IOV through some PCI Express* slots, but not on some other slots. Consult your manufacturer's documentation for SR-IOV support on your system.
Which hypervisors support SR-IOV on Intel® Ethernet Adapters?

Microsoft Hyper-V* (Windows Server 2012*)
VMware Sphere* 5.1
Xen Hypervisor*
KVM* (Kernel Based Virtual Machine)

Which guest operating systems (GOS) have virtual function drivers?

Virtual function (VF) drivers for guest operating systems are available for:

  • Windows Server 2012
  • Windows Server 2012 R2
  • Windows Server 2008* R2
  • Windows Server 2008
  • Linux* 2.6.30 kernel or later
  • Red Hat Enterprise Linux 6.0* and later
  • SUSE Linux Enterprise Server 11* SP1 and later
Where can I get the virtual function (VF) drivers?VF Drivers for Windows* are included in the Intel® Ethernet Software Package for Windows.
Intel® Ethernet software and drivers for Windows Server 2012*
Intel® Ethernet software and drivers for Windows Server 2008* R2
Intel® Ethernet software and drivers for Windows Server 2008

Linux* VF drivers are included with the distributions, or you can download them from Intel Download Center.
Network Adapter virtual function Driver for 82576-Based Gigabit Network Connections for Linux*
Network Adapter virtual function Driver for 82599-Based 10 Gigabit Network Connections

 

FreeBSD VF drivers can be downloaded from the FreeBSD Project.
e1000 driver for FreeBSD

How can I make SR-IOV work in Linux*?

An example is provided in Setting up Red Hat 5.4 Xen* for SR-IOV using the Intel 82576 GbE.

Note SR-IOV with the Intel® Ethernet Server Adapter X520 Series is not supported by the Red Hat 5.4 Xen* distribution. Use the Xen Hypervisor* from Xen.org with the Intel Ethernet Server Adapter X520 Series.
Can I use SR-IOV with Microsoft Hyper-V*?

Yes. Hyper-V in Windows Server 2012* and Microsoft Hyper-V Server 2012* enable support for SR-IOV–capable network devices and let an SR-IOV virtual function of a physical network adapter be assigned directly to a virtual machine. Earlier versions of Hyper-V do not support SR-IOV.

Can I use SR-IOV with VMware products?

VMware VSphere* 5.1 adds support for SR-IOV.

Note VMware VSphere* does not Support Simultaneous FCoE and SR-IOV.
VMware VSphere 5.1 adds support for SR-IOV. Intel® Ethernet Converged Network adapters support both Fibre Channel over Ethernet (FCoE) and SR-IOV. However, FCoE and SR-IOV cannot be configured simultaneously on the same physical port in VMware’s implementation of SR-IOV for Intel® Ethernet Adapters.
