OpenStack Introduction
OpenStack is an open source IaaS implementation that consists of a number of interrelated subprojects, including computing, storage, and networking. With the launch of the Apache protocol, more than 200 companies have joined the OpenStack project since its inception in 2010, including Att, AMD, Cisco, Dell, IBM, Intel, Red Hat and so on. T

OpenStack is known as the 21st Century Linux open source community, can foresee its development prospects is how vast.
OpenStack's core project was increased from the previous two to the following: Cloud Compute (Nova) project

Preface
I recently built an OpenStack Environment Based on VXLAN and found that the package to dump ovs interfaces is still quite troublesome. After many efforts, find some trouble shooting methods in the network environment of openstack.
In addition to common tools such as ping, host, traceroute, tcpdump, ip neighb
First, what is OpenStack?OpenStack is an open-source cloud management platform project that combines several key components to do the job. OpenStack supports almost all types of cloud environments, and the project goal is to deliver a simple, massively scalable, rich, standard, unified cloud management platform. OpenStack
purpose of this article has been achieved. Because this article describes the implementation of dynamic migrations on the OpenStack platform, readers must have a certain understanding of OpenStack.Introduction to Virtual machine migrationDynamic migration consists of two meanings, one is migration (migration), and migration is to move a user's virtual machine from one physical host to another. The second is dynamic, the dynamic meaning is in the proc

For questions about the choice of OpenStack version on Ubuntu, just look here.From 12.04 Lts, Ubuntu Cloud Archive allows users to install the updated OpenStack before the next lts version of Ubuntu is released. Take Ubuntu Server 12.04 Lts, canonical supports all OpenStack versions released from 12.04 LTS to the next LTS release until the next lts is the three m
Preface
Every time you mention deploying OpenStack is a very complex thing, and of course many people will mention the use of devstack to quickly deploy OpenStack, generally we use devstack to deploy the development environment, It can be implemented on a machine to deploy a standalone version of the OpenStack environment containing the main components, I have ne
OpenStack has become the first choice for many cloud computing vendors to build a private cloud. Many academic institutions also use OpenStack to build a small-scale test environment for students' experiments. Here we will share the process of using OpenStack Virtual Machine to build the Hadoop2.2.0 environment.
1. Prepare the VM Environment
I have recently read about Openstack and have been trying to install it. However, I have referenced a lot of information, which is not satisfactory. Since CentOS has been used for Linux, most Openstack installation is required on Ubuntu. I don't know why. I don't like Ubuntu. Maybe I think it's too fancy, and I always want to update something.

BKJIA exclusive Article] OpenStack is a set of platform software used to manage virtual machines. Instead of a single software, it integrates many components for collaboration. Simply put, for example, there are ten servers. In the case of VMware, we install esx or esxi on each server, and then install a vcenter, in the vcenter management interface, you can add the esx of ten servers to the vcenter by adding domain names or ip addresses. Similarly, Re

The resize (upgrade) function of openstack allows us to change the number of CPU cores, memory, and disk size of the Virtual Machine. Of course, the virtual machine can only be upgraded up and cannot be downgraded down. By analyzing the source code, we found that the resize process is actually a cold migration process, and the resize multi-transmits a flavor parameter. The following
Create the RHEL7 system image used by OpenStack, set the image, and install XRDP for remote access. 1. install the RHEL7.2 client in KVM; 2. set the NIC to dhcp and onboot = yes so that the virtual machine can automatically obtain the IP address; vim/etc/sysconfig/network-scripts/ifcfg-eth0 to ensure that the network can be connected. 3.
