1.2 Live Migration & SR-IOV

In Windows Server 2012, Live Migration can be performed with SR-IOV being used by a VM.

If the source and target systems support SR-IOV and the target has an available VF, the VM

will use the virtual function. If not, the VM will revert to the traditional path (VM-Bus).

Each SR-IOV capable network adapter exposes a fixed number of Virtual Functions, which

can be obtained by running the PowerShell command “Get-NetAdapterSriov”.

The document shows how to make use of VFs using Windows Server 2012, which is included

in the Windows Server 2012 distribution.

• A server platform with an available PCI Express* v2.0 eight-lane, 5.0 GT/s (Gen2) PCI

slot (PCI Express v2.0 and v1.0 lane requirements for 2 port 10Gb and 4 port 1Gb)

1.4 Software Requirements

• Windows Server 2012* Build 8370

2 Installation and Configuration

• Install the Intel

Converged Network Server Adapter X520 in an available

PCI-Express v2.0 x8 slot. (Ensure that the x8 slot is electrically connected

as a x8, some slots are physically x8 but electrically support only x4.

Verify this with your server manufacturer or system documentation.)

• Power up the server and enter the server’s BIOS setup making sure the

virtualization technology and Intel

VT-d features are enabled. The

screen shots below are examples of the options to change.
