Single-root input/output virtualization

In network virtualization, a single root input/output virtualization or SR-IOV is a network interface that allows a device on a Virtual LAN (e.g. virtual router, network adapter) to isolate resources for managability and performance reasons. A single physical PCI Express can be shared on virtual network using SR-IOV. The SR-IOV offers different virtual functions (VF) to different nodes (e.g. virtual machines) on a Virtual LAN.
