How to support OpenStack old versions？
by Tianhua huang 19 Apr '21

19 Apr '21

基于厂商诉求和OpenStack SIG PTG的讨论结论，结合openEuler当前多版本支持能力现状，OpenStack SIG计划在openEuler-20.03-LTS-SP2版本优先支持OpenStack的R版本，在后续SP版本中补齐OpenStack Q/S/T版本，但是OpenStack在T版本之前只支持python2，这就意味着支持OpenStack的R、Q、S等老版本需要在openEuler-20.03里面引入python2的软件包，请问社区对于在20.03-LTS-SP2/SP3版本中引入新的python2软件包的策略是什么？OpenStack SIG组希望将OpenStack的R版本软件包引入到openEuler-20.03-LTS-SP2的EPOL，策略上是否可行？谢谢大家！ =========================================================== Based on vendor requirements,OpenStack SIG PTG discussion conclusions, and current support capabilities of OpenEuler multiple versions, OpenStack SIG plans to preferentially support OpenStack R version in openEuler-20.03-LTS-SP2. OpenStack Q/S/T will be supplemented in later SP versions. However, OpenStack earlier than T supports only python2. This means that the python2 software packages need to be introduced to openEuler-20.03 for R, Q, and S. What is the community's strategy for introducing the new python2 software packages in 20.03-LTS-SP2/SP3? The OpenStack SIG team hopes to introduce the OpenStack R version to the openEuler-20.03-LTS-SP2 EPOL. Is it feasible? Thank you.

[OpenStack-SIG] OpenStack openEuler 上下游软件包版本比对面板
by Rui Chen 19 Apr '21

19 Apr '21

SIG的朋友们大家好，我们平时在SIG组的工作中需要对大量的OpenStack软件包和依赖包进行构建和验证，OpenStack社区上游发布的软件包就有200多个[1]，引入openEuler时需要的关联构建依赖和运行依赖就更多了，相信大家在检查软件包版本的时候都花费了不少精力和时间。我做了一个小工具可以对比OpenStack上游软件包和openEuler软件仓库中的软件包版本，可以在线查看 https://kiwik.github.io/os-version-checker/ ，支持PC和移动端，是基于Debian OpenStack team的开源工具os-version-checker开发的，并在github上开源[3]，工具使用github action的cron job，每天早上生成最新数据，与 OpenStack软件包的版本差异会用不同颜色表示，欢迎大家使用和提出改进建议。 Hello, SIG friends, we need to build and verify a large number of OpenStack software packages and dependency packages in the SIG team. The OpenStack community has more than 200 software packages in one release [1]. When we build openEuler packages, there are more associated build dependencies and running dependencies. I believe you should spend a lot of effort and time checking the software package version. I have made a tool to compare the OpenStack upstream packages with the packages version in the OpenEuler software repository. You can view https://kiwik.github.io/os-version-checker/ online. It supports PC and mobile devices. It is developed based on the open-source tool os-version-checker of the Debian OpenStack team. My tool os-version-checker for openEuler is hosted in Github [3] and open source again. The tool uses the cron job of Github action to generate the latest data every morning. The version differences between the tool and the OpenStack software package are displayed in different colors. You are welcome to use the tool and give suggestion.

openEuler kernel Meetup 4月9号北京站圆满结束 openEuler kernel SIG组于2021年4月9日在北京成功举办了kernel meetup。本次活动云集了来自华为、麒麟、PingCAP、申威、飞腾、万里红、armChina、兆芯、美团、复旦的行业领袖、业界资深专家、高校教授、社区maintainer、开发者，吸引了现场30人+，线上约300人参与。会上就内核技术、SIG组后续运作规划进行了充分研讨，收集了各厂商的诉求并进行答疑，对SIG组后续的工作开展和技术合作有着重大意义。来自麒麟软件的孙立明老师，对ARM64 KVM 虚拟化架构做了介绍，增进了大家对ARM64 架构虚拟化的理解。麒麟软件的郭皓老师提出了openEuler kernel 支持PREEMPT_RT 的想法和思路。期待openEuler 具备更高的实时性，促进其在嵌入式领域的应用。孙立明老师郭皓老师来自兆芯的张伟老师，对兆芯CPU的演进、特性，以及兆芯补丁合入openEuler kernel 的过程做了介绍。目前兆芯的补丁已经合入openEuler 4.19 内核，预计6 月底发布的 openEuler 20.03 LTS SP2 将支持兆芯CPU。兆芯与openEuler社区的紧密合作促成了 openEuler 对兆芯CPU的快速支持，张伟老师对此表示了称赞。张伟老师来自申威的崔巍老师就处理器接口、虚拟化支持、安全增强等话题与飞腾、兆芯专家进行了现场交流，并表达了积极参与openEuler 的愿望，期待openEuler 尽快支持申威全自主指令集架构，促进openEuler社区和申威生态的共同繁荣。崔巍老师来自华为的缪勰介绍了华为针对SCM介质研发的文件系统。该文件系统的原理基于华为OS内核实验室主任陈海波老师的论文Soft Updates Made Simple and Fast on Non-volatile Memory <https://www.usenix.org/system/files/conference/atc17/atc17-dong.pdf> 采用软更新（soft-update) 提供一致性保证，采用哈希表目录结构，消除循环依赖，提供的字节级读写能力显著降低了SoupFS的复杂性等技术。性能相比业界其他SCM 文件系统有显著的提升。来自华为的杨基鸿，介绍了性能调优的常用方法、工具和思路，并通过实际案例讲解工具的应用及性能分析的思路。线上与会同学表达了对TOP-down性能分析工具的强烈兴趣，我们后续会通过专题分享介绍更多技术细节。杨基鸿来自复旦大学计算机学院的张亮教授，针对如何推动高校参与openEuler提出了建设性意见，我们后续也会持续开展面向高校的交流合作活动。张亮教授 openEuler kernel SIG 的Maintainer 谢秀奇介绍了kernel SIG一年多以来的进展以及后续的运作、规划等。与会专家老师进行了充分的研讨，提出了在kernel SIG 建立committer 机制的想法，以Committer 为核心对openEuler 内核进行规划、开发和治理。谢秀奇本次meetup的成功举办，对kernel SIG的后续工作和发展有重大意义。期待各厂商、各单位、各开发者在openEuler 开源社区这个大平台下，共建、共享、共治，让 openEuler kernel走进千行百业，成为信息产业的基石。 openEuler kernel SIG openEuler kernel 源代码仓库： https://gitee.com/openeuler/kernel 欢迎大家多多star、fork，多多参与社区开发，多多贡献补丁。关于贡献补丁请参考：如何参与 openEuler 内核开发 <https://mp.weixin.qq.com/s/a42a5VfayFeJgWitqbI8Qw> openEuler kernel SIG 微信技术交流群请扫描下方二维码添加小助手微信，备注“交流群”或“技术交流”，加入 openEuler kernel SIG 技术交流群。

openEuler in WSL by Wang Haitao
by 海涛 16 Apr '21

16 Apr '21

Hello guys, I am a new intern in Huawei OpenEuler, my name is Wang Haitao I can use openEuler in WSL in my computer now. Here is my gitee repo, I store everthing in here https://gitee.com/ouyanghaitao/open-euler-in-wsl I have tryed two ways: 1. import openEuler docker image in wsl, so I can start it from wsl command shell. 2. develop a WSL launcher project, so I can start openEuler on the windows start menu. I will share my dev doc, written in Chinese and English. you can see it in my email or gitee repo. If you can follow my document, try to start OpenEuler in WSL, and put forward some issues, I would be very grateful! ======================= 大家好呀, 我是华为openEuler下刚来的实习生，我叫王海涛我现在可以在我的计算机上使用openEuler的WSL。这是我的gitee repo，我帮相关的东西都放这里了 https://gitee.com/ouyanghaitao/open-euler-in-wsl 我尝试了两种方法: 1. 在wsl中导入openEuler docker映像，这样我就可以从wsl命令shell启动它。 2. 开发一个WSL启动程序项目，这样我就可以在windows开始菜单上启动openEuler。我将分享我的中英文开发文档。你可以在我的邮件或gitee repo中看到它。如果你能跟着我的文档，尝试在WSL中启动启动openEuler，并提一些issue，我会感激不尽的！
