ARM64-VMM: CUSTOM KVM HYPERVISOR

Introduction

arm64-vmm is a minimalist, secure hypervisor designed to run microVMs on arm64 hardware. Built using Rust, it interacts directly with the Linux /dev/kvm API to configure CPU states, construct physical memory layouts, and handle device emulation.

Key Features

• Direct Linux KVM Integration — No bloated QEMU dependence.
• Minimal Devicetree Generation — Automatically generates devicetrees for guest kernels.
• Fast Boot Times — Booting kernel payloads to userspace in <15ms.
• VirtIO Console & Block — Clean, performant virtio bindings for console IO and disk access.
