openEuler Documentation

An open-source enterprise Linux distribution initiated by Huawei and incubated by the OpenAtom Foundation. Not a RHEL rebuild — its own kernel branch and full package build system, while keeping RPM/DNF habits.

Follow a complete task

Media, installation and first boot

Before you start: Choose openEuler media for the processor architecture and confirm the LTS line and boot requirements.

1. Download openEuler
2. Install openEuler on x86_64
3. openEuler operations and monitoring

Completion check: Match openEuler identity and architecture to the plan, boot its kernel and complete failed-service and operations checks.

Release and migration assessment

Before you start: Separate openEuler SP updates, cross-LTS moves and conversion from EL; consult the matching official matrix.

1. openEuler Versions and Lifecycle
2. openEuler 大版本迁移 · 中文
3. Migrating to openEuler from CentOS/EL

Completion check: Record a documented migration route, package/application compatibility and restore points; an unknown route remains an assessment.

Diagnose and verify recovery

Before you start: Record openEuler architecture, boot media and preceding kernel or driver changes.

1. openEuler 启动故障排障 · 中文
2. openEuler FAQ

Completion check: Boot the intended kernel without reproducing the failure, inspect boot logs and services, and preserve traceable evidence.

What openEuler 24.03 LTS brings

From openEuler’s own release announcement and release-rules article, each item with its source.

openEuler 24.03-LTS-SP4

24.03-LTS-SP4 openEuler 24.03 LTS SP4 Released 2024-06 · security support until 2027-03 Versions & lifecycle

AI-native The first AI-native open source OS openEuler 24.03 LTS is openEuler’s first AI-native open source operating system, covering mainstream models, frameworks and toolchains

Linux 6.6 Linux kernel 6.6 Linux kernel 6.6 delivers more balanced CPU scheduling, more efficient memory management, and more flexible resource utilization in virtual scenarios

Arm / x86 / RISC-V / LoongArch Arm, x86, RISC-V and LoongArch Images for all four architectures are available simultaneously

One release, images for four architectures at the same time

• The Arm, x86, RISC-V and LoongArch images of openEuler 24.03 LTS are available simultaneously
• An LTS version is released every two years; between LTS versions an innovation version is published every six months with six months of community support
• LTS versions get four years of community support (per the official release-rules article)

03 — Versions

Dual track: LTS and innovation

LTS with SPs for production, innovation releases for early access. Release status follows official openEuler announcements (no static snapshot here, by design).
