## What it is
Project ACRN is an open-source Type 1 (bare-metal) embedded hypervisor reference stack for running multiple software subsystems securely on consolidated IoT and embedded devices. It includes a device model for virtual device emulation and partitions systems into functional domains with guest OS sharing optimizations.

## Use cases
- run multiple operating systems on an embedded IoT device
- consolidate safety-critical and general-purpose workloads on one machine
- partition hardware into isolated functional domains
- emulate virtual devices for guest OSes on embedded hardware
- build a virtualization stack for automotive or industrial edge devices

## When to choose
- you need a lightweight Type 1 hypervisor for IoT or embedded hardware
- you want stronger isolation than hard partitioning but lighter weight than datacenter hypervisors
- you're building consolidated embedded systems with mixed-criticality workloads

## When to avoid
- you need full-featured datacenter virtualization with broad guest OS support
- your target is cloud or server workloads rather than embedded devices
- you need a Type 2 hypervisor running on top of a host OS
