We are pleased to announce the release of ACRN™ Hypervisor version 1.1 which introduces Hybrid Mode and support for Zephyr, VxWorks and Windows as new Guest Operating Systems.
In this reference release, we use Clear Linux* as the Service OS (SOS) and User OS (UOS). Android* and other Linux* based OSes can also be used as a UOS.
See the full release notes and latest documentation for more information about this 1.1 release.
Key features for this 1.1 release include:
Hybrid Mode Introduced
In hybrid mode, the hypervisor launches the Zephyr OS even before the Service OS is launched (pre-launched), with dedicated resources to achieve the highest level of isolation. This is designed to meet the needs of a Functional Safety (FuSa) certifiable safety OS.
Support for new guest Operating Systems
- The Zephyr RTOS can be a pre-launched Safety OS in hybrid mode. It can also be a post-launched (launched by Service OS, not the hypervisor) as a guest OS.
- VxWorks as a post-launched RTOS for industrial usages.
- Windows as a post-launched OS
Document updates
We have many reference documents available, including:
- Update: Using PREEMPT_RT-Linux for real-time UOS
- Zephyr RTOS as Guest OS
- Using VxWorks* as User OS
- How to enable OVS in ACRN
- Enable QoS based on runC container
- Using partition mode on NUC
Refer to the ACRN version 1.1 release notes for more details.
