Single Root I/O
Virtualization (SR-IOV)
is used to configure
devices into multiple
virtual devices that can
be used on virtual OS
installations. If supported
by the hardware and set
to enabled, all devices
within the system that
are SR-IOV capable are
configured to support SR-
IOV and I/O resources are
allocated to the device as
normal. If set to disabled,
I/O resources are not
allocated to the device.
If Alternate Routing ID
(ARI) is supported by
the hardware and set
to enabled, devices are
permitted to locate virtual
functions (VFs) in function
numbers 8 to 255 of the
captured bus number,
instead of normal function
numbers 0 to 7.
