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.
