Community Events ​

openEuler Space SIG Officially Established ​

On March 4, the openEuler community officially established the Space SIG with approval from the openEuler Technical Committee. Led by the Beijing Aerospace Microsystem and Information Technology Research Institute together with other organizations, the SIG is the first openEuler community group dedicated to spatial intelligence scenarios, including satellite constellations, deep-space exploration, UAVs, and eVTOLs. It aims to build an open, unified, and intelligent spatial computing ecosystem, providing an open-source software foundation for next-generation spatial applications.

openEuler Participates in FOSSASIA Summit 2026 ​

From March 8 to 10, FOSSASIA Summit 2026 was held in Bangkok, Thailand. As a Platinum Sponsor, openEuler joined global open-source developers, technology experts, and ecosystem partners at the event, sharing its latest operating system innovations for the AI era and exploring new opportunities for open-source collaboration.

openEuler Showcases AI Capabilities at KCD Beijing + vLLM 2026 ​

As a key event bringing together cloud-native and AI communities, KCD Beijing + vLLM 2026 was held on March 21. At the event, openEuler showcased its latest AI capabilities, including the DevStation intelligent development desktop and the assistant agent. The showcase attracted attention from developers and highlighted openEuler’s efforts in AI infrastructure and intelligent development.

openEuler Developer Day 2026 Scheduled ​

openEuler Developer Day 2026 (ODD 2026) will be held on April 25 in Changsha, bringing together developers to discuss the future of operating systems in the AI era.

The event will focus on key topics including tech requirements, feature planning, and release cycles for future openEuler LTS and innovation releases, as well as exploring new opportunities for open-source collaboration.

Key Technical Progress ​

openEuler 24.03 LTS SP3 RISC-V Enters LTS Maintenance ​

Following extensive community validation and stability improvements, openEuler 24.03 LTS SP3 RISC-V has officially entered the LTS maintenance phase. As the first LTS release supporting the RVA23 standard, it introduces initial support for the RISC-V server platform specification, enhances server support through RVCK, and adds support for the SpacemiT K3 platform. The community will continue to strengthen RVA23 support, kernel infrastructure, and the RISC-V software ecosystem throughout the LTS lifecycle.

Agent for Known Issue Analysis Goes Live ​

In enterprise O&M, troubleshooting often faces two challenges: valuable experience from previously resolved issues is scattered across tickets, internal documents, and engineers’ notes, while system logs are massive, diverse, and difficult to analyze efficiently.

To address these challenges, openEuler launched an agent for known issue analysis in March 2026, enabling intelligent fault diagnosis by combining historical knowledge retrieval and log analysis capabilities.

• Lightweight knowledge base MCP

The MCP enables the agent to retrieve historical known issues and match similar cases based on user-reported symptoms or log information. It then generates structured analysis reports covering symptoms, solutions, and verification steps, helping reduce mean time to repair.

• Log anomaly detection MCP

Designed for large-scale and complex enterprise logs, the MCP provides high-performance anomaly detection capabilities. It helps the agent identify potential issues from massive log data, improving diagnosis efficiency while reducing analysis costs.

openEuler CloudNative SIG Introduces Conch ​

With the rapid growth of AI agent projects such as OpenClaw, running agents directly on hosts or virtual machines introduces new challenges in security, isolation, and reliability. Agents with deep system access may contaminate the runtime environment due to issues such as prompt injection, model hallucination, improper configuration changes, or damaged libraries.

Therefore, the openEuler CloudNative SIG introduced Conch, a next-generation sandbox engine featuring strong isolation, extensibility, and millisecond-level startup. Conch provides a reliable execution foundation for agents, enabling safer and more efficient deployment.

Witty Assistant Brings AI-Powered O&M to openEuler ​

openEuler 24.03 LTS SP3 introduces Witty Assistant and an agent for known issue analysis, bringing AI-powered capabilities to enterprise O&M. Together, they help reduce repetitive troubleshooting by reusing historical issue knowledge, automatically analyzing faults, and generating structured diagnosis results, improving O&M efficiency and delivering a smarter maintenance experience.

Container Image Updates ​

During March, 35 application images were updated based on the openEuler 24.03 LTS SP3 base image. These updates covered AI, cloud, big data, database, storage, and other software categories.

The images are available on Docker Hub.

Hardware & Software Compatibility ​

As of March 31, 2026, a total of 2,603 products had passed openEuler hardware and software compatibility evaluation. 62 products were added during March: 49 from independent software vendors (ISVs), 11 from independent hardware vendors (IHVs), and 2 from operating system vendors (OSVs).

• Compatibility list.
