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?
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?The Intel® Ethernet Software Package for Windows includes VF Drivers for Windows*.The distributions include Linux* VF drivers, or you can download them from Intel Download Center.

You can download FreeBSD VF drivers from the FreeBSD Project.

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

The Red Hat 5.4 Xen* distribution does not support SR-IOV with the Intel® Ethernet Server Adapter X520 Series. 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. An SR-IOV virtual function of a physical network adapter can assign 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, you cannot simultaneously configure FCoE and SR-IOV on the same physical port in VMware’s implementation of SR-IOV for Intel® Ethernet Adapters.
