openstack requirements

Software requirements include 3 different tiers-business requirements, user requirements, and functional requirements. In addition, each system also has a variety of non-functional requirements. Business requirement represents a high-level goal for an organization or custome

the two are different, the host will be filtered out. For more implementation details, refer to the code here: Https://github.com/openstack/nova/blob/master/nova/scheduler/filters/image_props_filter.py Instance deployment After correct configuration of powervm, KVM's Nova compute service, and image attributes, the commands deployed on the virtual machine do not need to be specified with special parameters and settings. Deploy a powervm instance: nova

composition Three Basic Environment (1) We built the OpenStack environment as an example, a total of 5 machines, one as fuel Master, one as controller node, the other three as compute node. One of the basic requirements for hardware is to have three physical network ports (except fuel Master), the other is not very large requirements, the theory is certainly hi

No bootable device. Cause: The image of the volume that started the virtual machine does not contain boot loader. Resolution: For testing pu

The article summarizes, longitudinal, transverse, from the surface to the point, finally is the demand quality control. The requirement analysis of software must have a deep understanding of the original business, extraction, abstraction, sublimation process. Software requirements analysis is to extract from the user's business software system can help users solve the business problems, through the user's business problem analysis, the planning of

environment OpenStack deployment, here to explain the installation process on the virtual machine to demonstrate the description. My environment is the HP Notebook folio 9470, in fact, is a common office notebook, the reader can modify the virtual machine configuration according to the actual machine situation, I gave my configuration for reference only.Installation InstructionsHardware requirements

This tutorial is based on the Ubuntu12.04 edition, and it will help readers build a openstack minimized installation. I am the top of the Wuyue, translation more use of transliteration method, so the individual words and the original discrepancy, please understand. I am not a major in English, I think the most important thing is to understand the technology, and not the four level and grind in the boring English-Chinese translation, so my goal is loya

Openstack official website content: http://docs.openstack.org/grizzly/openstack-object-storage/admin/content/ Because I only focus on the part of openstack Object Storage, I did not write anything related to other modules (or I am relatively lazy). I may add it if necessary in the future. The translation level is limited. If a netizen finds an error during re

installation, configuration, operation, and troubleshooting of these OpenStack services, you should consider the following few steps when using production architecture deployment. Identify and implement the necessary core and optional services to meet performance and redundancy requirements. Security is enhanced using methods such as firewalls, encryption, and service policies. Automate th

As a core tutorial for OpenStack, we have come to the final summary. OpenStack currently has dozens of modules, this tutorial discusses the most important core modules: Keystone,nova,glance,cinder and neutron. Please look at the following figure: This figure is truncated from https://www.openstack.org/software/project-navigator/, which is the official 6 Core Service defined by

10. OpenStack Object Storage Service (SWIFT) configuration: I added two hard drives (SDB,SDC) to the compute node for storage, and the compute node in my build is the storage node, because the computer can't pull more virtual ... Brief introduction: There are four main components of Swift: Swift-proxy-server, Swift-account-server, Swift-container-server, Swift-object-server Swift-proxy-server (Proxy service): Externally provided object service API

, management Platform and other 15 services. The private cloud platform of Netease makes full use of the latest results of cloud computing open source. We have developed and deployed VM instances and cloud network services based on the keystone, glance, nova, AND neutron components of the OpenStack community.
