Through this article, you will be able to understand how to configure the hybrid hypervisor in openstack and the basic analysis of its implementation principles. This article analyzes the principles of the hybrid hypervisor scenario in openstack based on the actual development experience of the author in Nova, and introduces how to configure the hybrid hypervisor scenario in actual application scenarios.

hopes to help you use the OpenStack front-end to set up and manage your own public cloud or private cloud by providing the necessary guidance information. Ii. The basic structure of OpenStack Horizon (Dashboard): To provide users with a graphical Web front-end console for the management of OpenStack resources and services to make them relatively intuitive; Nova:

Well, we've already installed fuel master, and now we're ready to install OpenStack, so you can see the OpenStack main interface when the installation is complete.Continue yesterday, we went into the fuel UI and then "new OpenStack Environment" to create the OpenStack deployment environment.650) this.width=650; "src="

OpenStack very easy to scale: Increase compute nodes (increase Worker) when compute resources are insufficient to create a virtual machine When the customer's request volume is too large to dispatch, you can increase the Scheduler Driver FrameOpenStack is an open infrastracture as a Service cloud operating system that supports the industry's best technologies.

The following figure details the operating principle of KVM: KVM supports user-mode (userspace) processes to create virtual machines through the KVM kernel module using the virtualization technology of CPU. The Virtual Machine's vcpu is mapped to the thread in the process. The virtual machine's Ram is map

Libvirt is an application interface, daemon process, and management tool designed to manage platform virtualization technology more conveniently. It provides the following functions: Management of virtual clients Management of virtual networks and storage Suppor
