This change addresses a long-standing issue in rST documentation imported from XML.
That import process added backslash escapes in front of various characters. The three
most common being '(', ')', and '_'.
These instances are removed.

SR-IOV Encryption Acceleration
|
|
==============================
|
|
|
|
|prod-os| supports |PCI| |SRIOV| access for encryption acceleration.
|
|
|
|
|prod-os| supports |SRIOV| access for acceleration devices based on
|
|
Intel QuickAssist™ technology, specifically Coleto Creek 8925/8950, and C62X
|
|
chipset. Other QuickAssist™ devices are currently not supported.
|
|
|
|
If acceleration devices have to be used, the devices have to be present as
|
|
virtual devices (qat-dh895xcc-vfor qat-c62x-vf) on the |PCI| bus. Physical
|
|
devices (qat-pf) are currently not supported.
|
|
|
|
If hardware is present (for example, Intel AV-ICE02 VPN Acceleration Card) on
|
|
an available host, you can provide |VMs| with |PCI| passthrough access to one or
|
|
more of the supported virtual |SRIOV| acceleration devices to improve
|
|
performance for encrypted communications.
|
|
|
|
.. caution::
|
|
Live migration is not supported for instances using |SRIOV| devices.
|
|
|
|
To expose the device to |VMs|, see :ref:`Exposing a Generic PCI Device for Use
|
|
by VMs <expose-a-generic-pci-device-for-use-by-vms>`.
|
|
|
|
.. note::
|
|
To use |PCI| passthrough or |SRIOV| devices, you must have Intel VT-x and
|
|
Intel VT-d features enabled in the BIOS.
