[Announce] ACRN Open Source Ver1.6.1 Release Notes

Zou, Terry

Hi all,


We are very pleased to announce Version 1.6.1 release of ACRN. You can see the release blog from https://projectacrn.org/blog/ and detailed Release Notes in website https://projectacrn.github.io/latest/release_notes/release_notes_1.6.1.html


Version 1.6.1 features:

  • ACRN can now use libvirt to support VM orchestration based on OpenStack.

Libvirt is an open-source API library, daemon (libvirtd), and a command-line management tool (virsh) that decouples specific orchestrators (such as OpenStack) and hypervisors (such as ACRN). Our adding an “ACRN driver” allows libvirt to support ACRN. A libvirt based orchestrator can configure an ACRN guest domain’s CPU configuration during VM creation. We also support dynamic configuration for vCPU affinity via the ACRN Device Manager (acrn-dm). The ACRN configuration tool is also updated based on VM orchestration support. Refer to the ACRN-libvirt repo for more information.

  • CPU sharing and GVT-d are now enabled by default.
  • Platforms with multiple IO-APICs are supported.
  • VT-d Posted interrupts are supported.

Documentation Updates: many new and updated reference documents are available, including:


To learn more about ACRN: ACRN is a flexible, lightweight reference hypervisor, built with real-time and safety-criticality in mind, optimized to streamline embedded development through an open source platform. Check out the ACRN project portal (https://projectacrn.org/) for more information.
