-Compsable SR-IOV device
-=======================
-
-SR-IOV (Single Root I/O Virtualization) is an optional extended capability of a
-PCI Express device. It allows a single physical function (PF) to appear as
-multiple virtual functions (VFs) for the main purpose of eliminating software
-overhead in I/O from virtual machines.
-
-There are devices with predefined SR-IOV configurations, but it is also possible
-to compose an SR-IOV device yourself. Composing an SR-IOV device is currently
-only supported by virtio-net-pci.
-
-Users can configure an SR-IOV-capable virtio-net device by adding
-virtio-net-pci functions to a bus. Below is a command line example:
-
-.. code-block:: shell
-
-    -netdev user,id=n -netdev user,id=o
-    -netdev user,id=p -netdev user,id=q
-    -device pcie-root-port,id=b
-    -device virtio-net-pci,bus=b,addr=0x0.0x3,netdev=q,sriov-pf=f
-    -device virtio-net-pci,bus=b,addr=0x0.0x2,netdev=p,sriov-pf=f
-    -device virtio-net-pci,bus=b,addr=0x0.0x1,netdev=o,sriov-pf=f
-    -device virtio-net-pci,bus=b,addr=0x0.0x0,netdev=n,id=f
-
-The VFs specify the paired PF with ``sriov-pf`` property. The PF must be
-added after all VFs. It is the user's responsibility to ensure that VFs have
-function numbers larger than one of the PF, and that the function numbers
-have a consistent stride.
-
-You may also need to perform additional steps to activate the SR-IOV feature on
-your guest. For Linux, refer to [1]_.
