KubeOS is a lightweight operating system developed in the openEuler community for running containers and Kubernetes. This takl will introduce the KubeOS's OS image and Kubernetes cluster node upgrade solution and how to use KubeOS.

With widespread use of containers and Kubernetes, there are fewer requirements for operating systems. In addition, traditional operating systems maybe bring various problems like security, O&M overhead, and OS version splitting problems. This talk will discuss the current problems faced by OS management and upgrade and the concept of Container operating system. Then, share the design ideas and solutions of the container operating system KubeOS. Finally, introduce the architecture, functions, and use of KubeOS in detail. This talk is likely to be interesting to the O&M personnel, the system administrator, or anyone interested in how the OS of a cluster node becomes a cluster component.

This talk was amended on 3 February 2023 to swap the speakers, as the original speaker was unable to attend FOSDEM due to visa issues.

HIPPEROS is an upcoming open source RTOS that was developed at ULB and by a former spin-off company of ULB. The talk will be a presentation followed by an open discussion about the main architecture principles of the HIPPEROS kernel and OS, what platforms and architectures we support and our agenda regarding open source.

This multitasking RTOS is specifically designed to take advantage of multi-core platforms for critical, hard real-time applications that must be predictable. It targets high-end embedded platforms that exhibit heterogeneous parallelism. The HIPPEROS kernel is designed from scratch in order to support recent process models present in the real-time systems research literature. The RTOS is based on a micro-kernel with an asymmetric master/slave architecture. It allows to natively support parallel processor architectures, by dedicating one core to the heavy operations of the kernel (scheduling, memory management, etc.) and the other cores can then execute user mode application and serve real-time tasks with very few interferences.

The OS kernel was designed and implemented by a team made of people from the ULB PARTS laboratory (http://parts.ulb.ac.be/). The goal was to create a spin-off company around the topic of Real-Time Operating Systems, including the creation of a new micro-kernel for high-end embedded systems with an innovative software architecture, backed-up by research (both theoretical and applied), designed, developed and maintained with "good" (and agile) software design methodology. Within this business, a side objective was to maintain strong links with universities and the research world, by validating the OS design in an academic environment and continuous research activities.

Currently, the company is under liquidation. The state of the project is frozen but we started an ongoing initiative aiming to open source the code base. This would allow external contributions and therefore continuing maintenance and development of new features. HIPPEROS could then become a test ground for academics and industrials that aim to try new ideas regarding the reliability and efficiency of their systems. With no such undertaking, the code base might just disappear, therefore cancelling out the 7-year team effort.
