USE CASE: APEIRO-RA PROJECT

Cyberus Hypervisor @ SAP

Modular, secure, and high-performance by design: our hypervisor stack – based on KVM and Cloud Hypervisor – enables near-zero downtime updates, seamless integration, and near-native speed.

In close collaboration with the SAP CobaltCore team, we are co-designing a Kubernetes-based OpenStack distribution tailored for both enterprise and public sector needs. At the heart of this solution lies the open-source Cyberus Hypervisor, which delivers secure, auditable, and high-performance virtualization. Built for modern cloud environments, it integrates tightly with OpenStack-Nix to enable reproducible, modular, and infrastructure-as-code deployments. Thanks to its advanced capabilities in live migration, the stack ensures smooth and efficient VM mobility across environments, making it ideal for demanding use cases where uptime, flexibility, and security are essential.

CYBERUS HYPERVISOR ARCHITECTURE

The Core of our Cloud-Solution

Architecture diagram of Cyberus Hypervisor showing VM isolation, orchestration layers, and shared responsibility model

Secure and Reliable Isolation
Runs cloud hypervisor in VMX root mode—minimizing attack surface without sacrificing performance.

API-First Orchestration
Unified VM scheduler + external APIs enable fully automated provisioning, scaling, and lifecycle management.

Clear Responsibility Model
Distinct “Cyberus vs. Integrator vs. Shared” ownership boundaries streamline integration and support.

BENEFITS

The Benefits of our Hypervisor

Modular, secure, and high-performance by design—our hypervisor stack enables near-zero downtime updates, seamless integration, and near-native speed.

Modularity

Pluggable Components
Swap or extend hypervisor services (scheduler, APIs, add-ons) on demand with near-zero downtime.

Layered Abstractions
Thin base OS + KVM kernel + cloud hypervisor stack keeps each layer independent and replaceable.

Integrator-Friendly
Well-documented interfaces let your team plug in custom logic or third-party tools in minutes.

Security (Rust)

Memory-Safe Codebase
VMM written in Rust to eliminate classes of vulnerabilities (buffer overflows, use-after-free, etc.).

Auditable & Verifiable
Deterministic builds and clear module boundaries support code reviews, formal checks and compliance.

Performance

Near-Native Throughput
Minimal context switches deliver bare-metal-like I/O and CPU performance.

Elastic Resource Allocation
Rapid VM spin-up and real-time scaling ensure you only pay for exactly the resources you use.

Cache-Aware Scheduling
Intelligent placement keeps working sets hot and maximizes multi-tenant efficiency.
