Kernel-based Virtual Machine + KQEMU
OpenStack is a cloud manage platform , not a hypervisor. 轉自oSSLab 在 KVM(Kernel-based Virtual Machine) 裡面一直會談論到 QEMU 什麼是 QEMU 究竟在 KVM 的虛擬化中 QEMU 佔了什麼重要的地位. QEMU

Wrote by Stephen SpectorMay 18th, 2011  on OpenStack Blog The team at Mirantis published a new blog post today on deploying OpenStack on Fedora (http://mirantis.blogspot.com/2011/05/openstack-deployment-on-fedora-using.html). From the blog: In this article, we discuss our approach to performing an Openstack installation on Fedora using our RPM repository and Kickstart. When we first started working with OpenStack, we found that the most popular platform for deploying OpenStack was Ubuntu, which seemed like a viable option for us, as there are packages for it available, as well as plenty of documentation. However, our internal infrastructure is running on Fedora, so instead of migrating the full infrastructure to Ubuntu, we decided to make OpenStack Fedora-friendly. The challenge in using Fedora, however, is that there aren’t any packages, nor is there much documentation available. Details of how we worked around these limitations are discussed below. The complete blog post with detailed …

In the world of open source cloud computing few topics have collected more attention recently than the ongoing development of OpenStack, the cloud computing project launched by NASA and Rackspace. So, some people may not have been too surprised when Canonical said last week that OpenStack, and not Eucalyptus, would be Ubuntu’s future default cloud platform. However, Canonical’s decision to move away from Eucalyptus in favor of OpenStack could be risky. OpenStack is less than a year old and still very much in its infancy. Given all the publicity OpenStack has received, it might be fair to wonder whether Canonical was more concerned about being left behind than it was about the technology’s current efficacy. “A lot of folks figured it was a no brainer just because of the buzz. To be honest, that was not the only reason why we switched. If you switch to something just because it gets buzz, you’d be changing all the time,” said Robbie Williamson, the engineering manager for the Ubuntu serve…

Deply Nova with StackOps

[ENG] StackOps Distro

In my definition , It's a kind of SaaS. Help beginners to  deploy one or more private cloud. The assistant.
我會將他定義成一種SaaS服務，目前基本上用來協助佈署OpenStack 的私有雲。如果只需要擁有小規模的架構，這會是一個方便初期使用的好工具。

But, 目前的版本有兩個問題(two issues)

iptables rule for redirecting metadata request to API server on Nova-Compute node
Effect : failed to SSH

I believe that most of testers of OpenStack NOVA will face a problem with instance can ping but failed to SSH.Well , there r many possibilities .

There's simple map in my mind


Note: I forgot to draw a VIP for nova-network hosts public Virtual IP

StackOps

One of the interesting find in this conference was a tiny little company from Spain called StackOps. If I have to describe StackOps in a simplistic way, I would say “StackOps is to OpenStack what Ubuntu was for Linux”. StackOps makes deploying OpenStack cloud seamless. Anyone can download the ISO image of the distribution from their website and have an OpenStack cloud running in 8-10 minutes. Keep an eye on this startup. They are going to play a critical role in taking OpenStack to more places than even Rackspace and other ecosystem partners

OpenStack Conference And Design Summit: A RecapBy Krishnan Subramanian on May 6, 2011

How to implement [still thinking] I hope someone can discuss with me .... there're two diagrams
Note Public network==Corporate network
My purpose goal1-Access instance from public network cloud users. goal2-Using euca2ools to control openstack from cloud users host , so that API server should direct                connect public network. goal3-To avoid connection block of instance. In regular way , instance route from nova-network host.               Once nova-network dead , users will lose connection to instance. goal4-High availability of all services , especially nova-api & nova-network. goal5-Monitor NOVA hosts and instances. goal6-Fast deployment
