A Type-1 hypervisor, also known as a bare-metal hypervisor, is a virtualization layer that runs directly on a system’s hardware, bypassing the need for an underlying operating system. Unlike Type-2 hypervisors, which operate as software within a host OS, Type-1 hypervisors interact directly with the hardware, providing superior performance, security, and resource management.
Technical Background
Virtualization, as a concept, emerged to maximize hardware efficiency by allowing multiple operating systems to run on a single physical machine. Traditional computing environments often suffered from inefficiencies such as underutilized resources and OS incompatibilities. The introduction of Type-1 hypervisors revolutionized this landscape by enabling hardware partitioning, ensuring workload isolation, and improving system reliability.
A Type-1 hypervisor manages multiple virtual machines (VMs), each with its own operating system, by abstracting hardware resources like CPU, memory, and I/O devices. It provides direct access to these resources, ensuring near-native performance. The hypervisor also enforces strict isolation between VMs, which is crucial for security in environments requiring high assurance.
PikeOS: A Modern Type-1 Hypervisor
SYSGO’s PikeOS is a modern Type-1 hypervisor designed with Safety-critical and Security-focused applications in mind. Unlike generic hypervisors aimed at enterprise IT workloads, PikeOS is engineered for embedded systems, real-time applications, and mixed-criticality environments. It offers partitioned multi-core execution, ensuring that safety-critical tasks operate alongside less critical functions without interference.
Core Capabilities of PikeOS:
- Microkernel-based Architecture: PikeOS is built on a small, highly secure microkernel, minimizing the attack surface while maximizing performance and determinism
- Real-Time Capabilities: It supports hard real-time execution, ensuring deterministic behavior, which is essential for industries like aerospace, automotive, and industrial automation
- Safety & Security Certifications: PikeOS complies with industry standards such as DO-178C (Avionics), ISO 26262 (Automotive), IEC 61508 (Industrial Safety), and Common Criteria (Security assurance), making it a preferred choice in regulated sectors
- Multiple Guest OS Support: PikeOS enables multiple OS instances (such as ELinOS, Linux, Android, and legacy systems) to run concurrently on the same hardware while maintaining strong isolation
- Resource Partitioning: It ensures controlled resource allocation, preventing one partition from interfering with another, a critical feature for mixed-criticality applications
Customer Benefits
Organizations leveraging PikeOS gain several advantages:
- Increased System Security: PikeOS ensures strong isolation, preventing Security breaches between different virtualized workloads
