| 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* vSphere 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 8*
- Windows Server 2008 R2*
- Windows Server 2008*, 32-bit and 64-bit
- Linux* 2.6.30 kernel or later
- Red Hat Enterprise Linux 5.4* and 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 Microsoft 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*
Intel® Ethernet software and drivers for Windows 8*
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-IOVcapable 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 VMwares implementation of SR-IOV for Intel® Ethernet Adapters. | |
