Overview

This project adds virtual machine introspection to the KVM hypervisor.

Virtual Machine Introspection is a technology that aims to understand the guest's execution context, solely based on the VM's hardware state, for various purposes:

• Debugging
• Malware Analysis
• Live-Memory Analysis
• OS Hardening
• Monitoring
• Fuzzing

See the presentations section for more information.

This project is divided into 4 components:

• kvm: linux kernel with vmi patches for KVM
• qemu: patched to allow introspection
• nitro (legacy): userland library which receives events, introspects the virtual machine state, and fills the semantic gap
• libvmi: virtual machine instrospection library with unified API across Xen and KVM

At the moment, 2 versions of VMI patches are available for QEMU/KVM in this repository:
