EulerOS

<h2 id="kunlun-mission-critical-server">KunLun Mission Critical Server</h2>
EulerOS 2.0, running on the Huawei KunLun Mission Critical Server, was certified in 2019 as conforming to the <a href="/facts/Single_UNIX_Specification/w1ba5bDt">Single UNIX Specification</a> (UNIX 03);<a class="footnote-ref" id="fnref:11" href="#fn:11">11</a> however. the certification expired in September 2022.<a class="footnote-ref" id="fnref:12" href="#fn:12">12</a> 
EulerOS/KunLun allows replacing <a href="/facts/Central_processing_unit/Jxp1bqMV">central processing unit</a> board modules and memory modules without <a href="/facts/Shutdown_(computing)/RcbxS9z9">stopping the OS</a>. <a href="/facts/Hot_swapping/Jn56Jw3h">Hot swapping</a> of CPU and memory is provided by EulerOS.<a class="footnote-ref" id="fnref:13" href="#fn:13">13</a>

<h2 id="code-shared-with-harmonyos-and-openharmony">Code shared with HarmonyOS and OpenHarmony</h2>
EulerOS with openEuler shares technology with Huawei's mobile operating system, <a href="/facts/HarmonyOS/pgEBr657">HarmonyOS</a> including BiSheng Compiler, distributed DSoftBus technology, OpenHarmony distributed file system (HMDFS), <a href="/facts/EROFS/GlUBsKfa">EROFS</a> read-only file system and native <a href="/facts/App_(file_format)/DC1Ts3BJ">HAP</a> file format. Huawei plans to unify additional components between both OSes.<a class="footnote-ref" id="fnref:14" href="#fn:14">14</a><a class="footnote-ref" id="fnref:15" href="#fn:15">15</a>

<h2 id="nestos">NestOS</h2>
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.<a class="footnote-ref" id="fnref:16" href="#fn:16">16</a>
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 <a href="/facts/Kubernetes/CI61Msu0">Kubernetes</a>, and improvements to its OpenStack system.<a class="footnote-ref" id="fnref:17" href="#fn:17">17</a>
