EulerOS

Commercial Linux distribution

EulerOS is a commercial Linux distribution developed by Huawei based on Red Hat Enterprise Linux[2] to provide an operating system for server and cloud environments.[3][4] Its open-source community version is known as openEuler, of which source code was released by Huawei at Gitee on December 31, 2019 that is Multikernel based. EulerOS itself officially launched September 23, 2021[5] alongside to openEuler publicly on September 25, 2021.[6] [7][8]

Quick Facts Developer, OS family ...

OpenEuler 21.09 version launched with new file system called EulerFS, also a kernel upgrade that is organized similar to classic HarmonyOS and OpenHarmony multikernel architecture that carries both RTOS kernel and Linux kernel on October 1, 2021. Also, the operating system supports, UniProton RTOS kernel.[9]

OpenEuler became an open-source project operated by OpenAtom Foundation after Huawei donated the source code of openEuler to the foundation on November 9, 2021.[10][11]

KunLun Mission Critical Server

EulerOS 2.0, running on the Huawei KunLun Mission Critical Server, was certified to conform to The Open Group's UNIX 03 standard, however the certification expired in September 2022.[12]

EulerOS/KunLun allows replacing central processing unit board modules and memory modules without stopping the OS. Hot swapping of CPU and memory is provided by EulerOS.[13]

Code shared with HarmonyOS

EulerOS shares kernel technology with Huawei's mobile operating system, HarmonyOS. Huawei plans to unify additional components between both OSes.[14]

NestOS

In November 2021, NestOS, an operating system based on open source EulerOS was launched. It incorporates the features of EulerOS, enhancing its capabilities in the cloud to cater to specific needs. NestOS, while maintaining the EulerOS ecology, brings its own features for various applications.[15]

In October 2022, the openEuler community updated the NestOS operating system to the new version based on the openEuler 22.09 version that include enhanced features to the system with nestos-assembler container image, optimized K8S, and improvements to its OpenStack system.[16]
