openstack foundation

Lift the installation of OpenStack, the whole people feel bad, for nearly a week time also failed to fix Redhat, CentOS 6.5 system installation, finally changed to CentOS7.0 last installation success. In order to later less detours, write down their own dull footsteps.The first time you install OpenStack, the server you get is a Redhat6.5 system with a CentOS6.5 system disc in hand. Developers are very lazy

The first contact with OpenStack, this piece is more headache, different documents, settings will vary, and can work, in the end which is correct? I'm afraid it's hard to come to a conclusion, here is a summary, the day sent to the mailing list for advice.The following settings, the final result, is that there is a network card into bridge, I understand bridge, is a switch, the virtual machine on the above can communicate with each other.The following

Label: Disclaimer: The recent installation of the kilo version of OpenStack found that there were very few existing web tutorials and that most of the tutorials did not install successfully, So write this tutorial. The installation of OpenStack is complex, and this tutorial does not guarantee that it will be installed successfully in different environments. Personal installation tutorials are also prone

The difference in version 12.04 is that this is an LTS (LongTermSupport) release, which means that Canonical has to support it for five years. Further, Canonical also guarantees porting support for OpenStackto12.04 in the next four versions, providing enterprise users with the prospect of stable operating system. In the cloud era, Ubuntu12.04 includes OpenStackEssex. The support for OpenStack is a transformation. Previous Ubuntu1 The difference in ve

This blog post has been quietly in the draft box for more than half a year. If it is not asked for some reason or the loss caused by ignoring it, I do not know when to complete it. I am grateful for the setbacks I 've experienced during this period. I hope you can give me more determination! This article attempts to describe in detail the complete process of creating a virtual machine in openstack, from the user's request to the successful running of

Apt-get install openstack pkg troubleshooting The operating system is Ubuntu 14.04. During the installation of the Openstack software package, the DNS of the host is correct and the repository of the software source is correct. Why is there always a software package installation error? The following error is reported: # Apt-get install cinder-api cinder-scheduler cinder-volume python-cinderclient-y Reading

Many of our partners are confused about how to learn openstack. The main reasons for the analysis are as follows:1. I don't know what kind of operating system to deploy?Openstack is deployed in centos7 or later versions in the enterprise production environment. openstack does not support Windows systems. We also hope that you do not deploy the system on the wuban

Recently, when looking for a job, I was asked some principles of Swift's bottom, so I decided to take notes in order to be able to impress. The following is reproduced by (http://www.openstack.cn/?p=776) --Openstack Swift Open Source cloud storage technology Analysis The OpenStack Swift Open source project provides an elastic, scalable, highly available distribut

Open Stack Compute Infrastructure (Nova) Nova is the computational organization controller in the OpenStack cloud. All activities that support an instance (instances) lifecycle in the OpenStack cloud are handled by the Nova. This makes Nova a platform for managing computing resources, networks, certifications, and scalability requirements. However, the Nova itself does not provide any virtualization capabi

The code for the Nova part of OpenStack has been studying for a while. Especially want to know, how to debug the code with Eclipse, also in the Forum asked others, no results, no one reply to me. Finally, I found out the way out.Let's write down the path of your exploration. I am an OpenStack environment built with Devstack. The build step can be found in one of my other blog posts.My Nova code does not hav
