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 2016*
  • Windows Server 2012*
  • Windows Server 2012* R2
  • Linux* 2.6.30 kernel or later
  • Red Hat Enterprise Linux 6.0* and later
  • SUSE Linux Enterprise Server 11* SP1 and later
  • Ubuntu 14.04 LTS and 16.04 LTS
Where can I get the virtual function (VF) drivers?The Intel® Ethernet Software Package for Windows includes VF Drivers for Windows*:Linux* VF drivers are available from the following locations:

You can download FreeBSD VF drivers from:

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

Most Linux* distributions support SR-IOV with the Intel® Ethernet Network Adapters.

Can I use SR-IOV with Microsoft Hyper-V*?

Yes. Hyper-V in Windows Server 2012*, Windows Server 2012* R2 and Windows Server 2016* include 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 don't support SR-IOV.

Can I use SR-IOV with VMware products?

VMware vSphere* 6.5 and 6.7 supports SR-IOV.

Note VMware vSphere* 6.5 and 6.7 don't support SR-IOV on 1Gb products.
Note VMware vSphere* doesn't Support Simultaneous FCoE and SR-IOV.
VMware vSphere 6.5 and 6.7 supports SR-IOV. Intel® Ethernet Converged Network X520, X540, and X550 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.
