一年多来，我一直在忠实地进行 OpenStack 的安装，记录笔记和文档，了解如何操作该软件，并且最重要的是，报告我遇到的任何错误。目的是评估 OpenStack 作为一种可行的云托管平台。问题在于，我忠实地进行 OpenStack 安装已经一年多，跟踪版本之间的变化（以及版本内部的变化），虽然该项目正在取得很大的进展，但从潜在的最终用户和商业客户的角度来看——在拥有能够交付承诺并能向我的雇主展示的东西方面，耐心正在逐渐消失。
几周前，我将此内容发布到 OpenStack 邮件列表
Dear all, I had my first sleepless night last night after a conversation I had in work regarding an OpenStack installation. We are a planning an OpenStack install but I've failed to demonstrate OpenStack running in our environment and yet packages are now being tagged up with RC. As big a supporter as I am, I'm struggling with the justifications when I have nothing tangible to show. The real questions are being posed to me on why we're looking at OpenStack and not CloudStack or Eucalyptus - they have installations that we can turn to. I was hoping Essex would help answer these questions relatively simply, but the opposite has happened - I am struggling to get OpenStack Essex working under Ubuntu - 11.10 and 12.04. There are a few issues I am hoping the community can address...

我已精疲力竭，几乎要放弃了——一年时间留下了一道道伤疤。
然而，几个小时内，情况开始发生变化。人们一个个地回应我的请求。这种回应简直非同寻常。个人贡献者、核心开发者、商业推动者都出来提供帮助——对我来说最令人欣慰的是，他们真正理解我的问题。来自最大公司的具有 4 小时 SLA 的昂贵支持合同，在相同的时间范围内提供的有效解决方案更少。在这一周的时间里，我从根本性的失败，到每天解决问题，取得了进展。从 Keystone 问题，到 Nova 的错误配置；从 Horizon 错误到简单的操作失误——所有需要的只是保证和指导，我遇到的只是错误，或者只是简单的错误配置。
我得到了协助安装的承诺，在 IRC 上进行特定问题的会话——对我来说同样重要的是，涵盖了我的问题，我得到了保证 OpenStack 正在使用并且可以正常工作。
在过去的几周里，在实际发布候选版本之前所取得的进展简直令人惊叹。我试图用后续内容来表达我的感受，发给了社区
Dear all, You might know me from such emails as "Agggh, I can't get this thing to work and its close to RC status!" and such bugs as "Why is this only affecting me?" so I thought I'd share my gratitude to everyone that has come out to help make life a lot less stressful for me. Over the course of just a week I've gone from despair and frustration to almost wanting to shout from the rooftops the achievements that have been made in OpenStack and my own deployments and testing. Whilst many of you might still be on that rocky road, I can assure you that there is light at the end of the tunnel. And it's quite bright too...

很明显，我的问题源于期望——既来自 OpenStack，也来自 Ubuntu。作为最终用户，如果该最终用户负责推动战略——OpenStack 是一种产品，而不仅仅是一组相互连接的 Python 脚本和项目。安装体验与软件的功能一样重要，以确保在企业环境中的采用。第一印象从这个关键阶段开始。解释你在安装过程中从 GitHub 上下载源代码补丁，这不是我愿意批准或想要做的事情。
自从 Essex RC 包发布以来，安装变得轻而易举。信心倍增，工作重心从虚假开始和尝试运行基本功能，转移到规划裸机配置和所需的特定配置步骤。
大家做得太棒了，你们力挽狂澜。
