middleware, all cells share the NOVA-API under local, sharing globally unique Keystone 。 The official website manual mentions cell immature (considered experimental), the Paris summit also mentions the cell pain point, although now has entered the K version iteration development, but I have not heard the industry mature uses the Cell case.

Use of Nova-RPC rabbitmq English looks a little hard. In Chinese. Rabbitmq and Nova RabbitMQ is a message component used in the OpenStack cloud. RabbitMQ is located in the middle of two nova components, so that the two components can communicate with each other in loose coupling. More precisely, the nova component uses

Openstack compute (NOVA) Function Analysis Openstack compute provides a cloud tool for an organization. Its functions include running Virtual Machine instances,Manage networks and control cloud access through users and projects. The most basic open-source project of openstack is named Nova. It provides software that can control the infrastructure as a service (IAAS) cloud computing platform,

The previous Cloudman analyzed the Nova launch, shut off and start operations in detail through the log.I wonder if you have mastered the skills of log analysis now?Let's check it out today.This section discusses the relatively simple operation of Nova: Reboot and Lock/unlock.I will first explain the theoretical knowledge of these operations, and then leave the log analysis for everyone to complete.Everyone

based on the Nova code in the OpenStack kilo release, new computing resources are available for specific users in specific projects: Vcpus, RAM statistics interface. The computational resource statistics granularity in raw OpenStack reaches the project level only. Therefore, a new statistical interface for individual users is required. The idea is to traverse through the Nova internal interface all the VM e

Implementation principle of VNC proxyVNC is an important function provided by Nova to access virtual machines. Users can access it through websocket or Java clients. The function of accessing a virtual machine through websket has been integrated into horizon, and the corresponding software needs to be installed first through the Java client. To make it easier for users to access virtual machines, Nova uses

Tags: Heat Nova servergroup openstackNow, Nova can use commands to create a server group. VMS in the server group can specify some policies. These policies include affinity and anti-affinity. Affinity indicates that all VMS should be installed on one host as much as possible, and anti-ffinity indicates that VMS should be arranged on different hosts as much as possible. The command to create a server-group i
