High-Level Design Guides¶
The ACRN Hypervisor acts as a host with full control of the processors and the hardware (physical memory, interrupt management, and I/O). It provides the User OS with an abstraction of a virtual platform, allowing the guest to behave as if it were executing directly on a physical processor.
These chapters describe the ACRN architecture, high-level design, background, and motivation for specific areas within the ACRN hypervisor system.
