ACRN v1.6.1 (May 2020)

We are pleased to announce the release of ACRN version 1.6.1.

ACRN is a flexible, lightweight reference hypervisor that is built with real-time and safety-criticality in mind. It is optimized to streamline embedded development through an open source platform. Check out What is ACRN for more information. All project ACRN source code is maintained in the https://github.com/projectacrn/acrn-hypervisor repository and includes folders for the ACRN hypervisor, the ACRN device model, tools, and documentation. You can either download this source code as a zip or tar.gz file (see the ACRN v1.6.1 GitHub release page) or use Git clone and checkout commands:

git clone https://github.com/projectacrn/acrn-hypervisor
cd acrn-hypervisor
git checkout v1.6.1

The project’s online technical documentation is also tagged to correspond with a specific release: generated v1.6.1 documents can be found at https://projectacrn.github.io/1.6.1/. Documentation for the latest (master) branch is found at https://projectacrn.github.io/latest/. ACRN v1.6.1 requires Clear Linux OS version 33050. Follow the instructions in the Getting Started Guide for ACRN Industry Scenario.

Version 1.6.1 major features

What’s New in v1.6.1

  • ACRN ensures libvirt supports VM orchestration based on OpenStack

    • libvirt is an open-source API, daemon, and management tool as a layer to decouple orchestrators and hypervisors. By adding a “ACRN driver”, libvirt can support ACRN. Please refer to ACRN-libvirt.
    • Supports the libvirt-based orchestrator to configure a guest domain’s CPU configuration during VM creation.
    • Supports dynamic configuration for vCPU affinity via acrn-dm
    • ACRN configuration tool updated based on VM orchestration support.

  • Enable CPU sharing and GVT-d Graphics virtualization by default.

  • Supported platforms with multiple IO-APICs

  • Supported VT-d Posted Interrupts
