StarlingX IA Feature Sub-project

This project is for work items to enable Intel Architecture specific features.

Team Information

  • Project Lead: TBD
  • Technical Lead: TBD
  • Core Reviewers: TBD
  • Contributors: TBD

Team Objective / Priorities

  • Validate that existing IA Features already supported in StarlingX are working correctly
  • Address any defects in IA Feature support
  • Add support for new IA features


All story board stories and launchpad bugs created for this team should use the tag "stx.ia"

IA Features in already in StarlingX

Feature Description Baseline Use Cases Implementation Testing Status
Vt-X Accelerates virtual machines to near bare metal performance Xeon / XeonD Near native virtualized CPU performance Performance enhancement of VMs, live migration from one Intel CPU generation to another
Vt-D Enables physical NICs and/or GPUs to be mapped directly to virtual machine Xeon / XeonD Native I/O performance PCI Passthrough and SR-IOV support
AVX-512 Enables high performance vector workloads Xeon Skylake, Xeon Scalable Processor Telecom, AI, high performance storage, encryption and compression Enhanced KVM performance, guest AVX-512 support
Trusted Execution Technology Used to attest system authenticity and state TPM 2.0 Secure boot and verified system state Secure boot, TPM 2.0 storage of communication keys, vTPM 2.0 support in guests.
AES-NI Accelerates encryption/decryption Xeon Westmere + Full disk encryption and faster communications Linux encryption performance enhancements
UEFI Boot Secure Boot UEFI spec 2.6+ Secure boot and faster boot Secure boot and fast boot
DPDK Acceleration library for networking Intel DPDK High speed VM-to-VM networking Optimized DPDK libraries
QuickAssist Hardware-based compression and encryption Coleto Creek, VT-d Exposing QuickAssist engine to VMs and virtualization of QuickAssist across VMs Support PCI passthrough and SR-IOV access for VMs to QuickAssist accelerators
Enhanced Platform Awareness (EPA) Set of enabling features that take full advantage of Intel Architecture through OpenStack N/A Performance / determinism controls such as core pinning, NUMA awareness / controls, hyperthreading awareness / controls, CPU model selection Suite of features that provide fine grained control for VMs. Can specify core pinning, NUMA affinity to vSwitch and NICs, split NUMA VMs, hyperthreading isolate or require, select CPU model to enable / disable CPU capabilities / instruction sets, huge page sizes.
BMC / IMPI Integration with BMCs for hardware monitoring N/A Discovery of and monitoring of hardware through BMC using IPMI Integration with BMCs to discover and collect hardware sensor data with capability to alarm on the values.
