What Virtual Open Systems does
Virtual Open Systems SAS is a French SME founded in 2011 and headquartered in Grenoble, specializing in open-source KVM-based virtualization for heterogeneous ARM, RISC-V, and x86 multicore embedded systems. Its product portfolio centers on VOSySmonitor, a low-latency ARM TrustZone monitor layer that achieved ISO 26262 ASIL-C certification and underpins the company's automotive safety-critical positioning, alongside VOSySmcs (automotive mixed-criticality virtual cockpit stack), VOSySIoT (industrial IoT edge stack), VOSYSwitch (NFV virtual switch), VOSySmonitoRV (RISC-V mixed-critical monitor), VOSySmonitorX86 (x86 mixed-critical monitor), and supporting components such as vFPGAmanager, vManager, VOSySzator, and API Remoting. The technology enables customers to consolidate multiple operating systems — general-purpose OS such as Linux or Android alongside RTOS environments — onto a single SoC with strict temporal and spatial isolation, addressing ECU consolidation in automotive, edge processing in industrial IoT, NFV acceleration in telecom, and HPC accelerator virtualization in cloud workloads.
The company operates a B2B enterprise go-to-market combining subscription-based software licensing (VOSySmonitor and downstream products) with project-based custom development, consulting, and training services delivered directly to OEMs, Tier-1 suppliers, and silicon vendors. Revenue-relevant partnerships are concentrated with major automotive SoC vendors — Renesas (R-Car H3/M3), NXP (S32G), and MediaTek (MT2712) — and the company participates in 15+ EU-funded research consortia spanning FP7, H2020, and Horizon Europe (VITAMIN-V, AERO, NANCY, EVEREST, ExaNeSt, ExaNoDe, SESAME, dReDBox, DREAMS, vIrtical, TRESCCA). The company is a Linux Foundation member, contributes to Automotive Grade Linux's EG-Virt working group, and holds Arm Automotive Developer Community partner status. The firm is privately held with 1-10 employees, no disclosed funding rounds, and operates as a recognized JEI (Jeune Entreprise Innovante) with CIR research tax credit eligibility.
