What are programs ? The OpenStack project mission is to produce the ubiquitous Open Source Cloud Computing platform that will meet the needs of public and private clouds regardless of size, by being simple to implement and massively scalable. OpenSta…

Why do we need it, whatever it is? VM unicast, multicast and broadcast traffic flow is detailed in my previous post: Tunnels in Openstack Neutron TL;DR: Agent OVS flow tables implement learning. That is, any unknown unicast destination (IE: MAC addre…

Puppet Openstack Design Summit小结 经过Puppet Openstack社区的不断努力,Puppet Openstack社区目前提供的Official Modules已经成熟,直接被用于Mirantis Fuel,Redhat PackStack等主流的部署工具中. 因此从Juno版本开始,社区的重心逐渐地转移到如何提供更全面的测试,如何抽取公共库以及规范架构等等代码的优化工作上. 本次Puppet Openstack Work Session放在古色古香的Aoi会…

Neutron 里面的 extension 和 plugin 是非常相似的两个概念,我花了好久才貌似搞懂了两者的区别,还不一定完全正确. 在OpenStack 的官网wiki中,可以找到它们两个的定义: Plugin: Neutron exposes a logical API to define network connectivity between devices from other OpenStack services (e.g., vNICs from Nova VMs). The…
