|
||
<p>SR-IOV (Single Root Input/Output Virtualization) can isolate PCIe devices
|
||
to improve performance that is similar to bare-metal levels. SR-IOV consists
|
||
of two basic units: PF (Physical Function), which supports SR-IOV PCIe
|
||
extended capability and manages entire physical devices; and VF (Virtual
|
||
Function), a “lightweight” PCIe function that is a passthrough device for
|
||
VMs.</p>

<p>When an SR-IOV capable device is initialized, all access to the

configuration space will passthrough to the physical device directly.

The Service VM can identify all capabilities of the device from the SR-IOV
|

extended capability and then create a <em>sysfs</em> node for SR-IOV management.</p>
