SR-IOV Ethernet Interfaces
|
|
==========================
|
|
|
|
An |SRIOV| Ethernet interface is a physical |PCI| Ethernet |NIC| that
|
|
implements hardware-based virtualization mechanisms to expose multiple virtual
|
|
network interfaces that can be used by one or more virtual machines
|
|
simultaneously.
|
|
|
|
The PCI-SIG |SRIOV| specification defines a standardized mechanism to create
|
|
individual virtual Ethernet devices from a single physical Ethernet interface.
|
|
For each exposed virtual Ethernet device, formally referred to as a |VF|, the
|
|
|SRIOV| interface provides separate management memory space, work queues,
|
|
interrupts resources, and DMA streams, while utilizing common resources behind
|
|
the host interface. Each VF therefore has direct access to the hardware and can
|
|
be considered to be an independent Ethernet interface.
|
|
|
|
The following limitations apply to |SRIOV| interfaces:
