SR-IOV Encryption Acceleration

supports access for encryption acceleration.

supports 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 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 with passthrough access to one or more of the supported virtual acceleration devices to improve performance for encrypted communications.

Caution

Live migration is not supported for instances using devices.

To expose the device to , see Exposing a Generic PCI Device for Use by VMs <expose-a-generic-pci-device-for-use-by-vms>.

Note

To use passthrough or devices, you must have Intel VT-x and Intel VT-d features enabled in the BIOS.
