ACRN Hypervisor Release Version 3.0

By June 29, 2022Blog

We are pleased to announce the release of ACRN™ hypervisor version 3.0.

What’s New in v3.0

The ACRN v3.0 release offers a major developer experience update including a new Configurator UI simplifying setup for the hypervisor and VMs, adds additional supported hardware for industrial use cases, Debian packaging, and new features and enhancements.

Redesigned ACRN Configuration

We heard your feedback: ACRN configuration is difficult, confusing, and had too many parameters that were not easy to understand. Release v3.0 features a new ACRN Configurator UI tool with a more intuitive design and workflow that simplifies getting the setup for the ACRN hypervisor right. You’ll also see changes for configuring individual VMs. We’ve greatly reduced the number of parameters needing your attention, organized them into basic and advanced categories, provided practical defaults, and added error checking so you can be much more confident in your configuration before building ACRN. This is our first major step of continued ACRN user experience improvements.

Commercial off-the-shelf Tiger Lake machine support

The Vecow SPC-7100 system is validated and supported by ACRN. This is a commercially available 11th Generation Intel® Core™ Processor (codenamed Tiger Lake) from Vecow.

A Windows User VM can now shut down or reset the system gracefully.

This supports a community-requested user model where a Windows-based VM provides a system management interface that includes being abot to shut the system down or restart.

Real Time Clock (RTC)

Each VM now has its own PC/AT-compatible RTC/CMOS device emulated by the hypervisor. With this, we can avoid any sudden jump in a VM’s system clock that may confuse certain applications.

ACRN Debianization

We appreciate a big contribution from the ACRN community! Helmut Buchsbaum from TTTech Industrial submitted a “debianization” feature that lets developers build and package ACRN into several Debian packages, install them on the target Ubuntu or Debian OS, and reboot the machine with ACRN running.
