We generally use the onehost, onevm, and onevnet command line tools to manage the OpenNebula cloud computing platform. However, a project team developed the OpenNebula Management Console Management tool based on PHP and MySQL, the installation and configuration are not very complex, which is similar to configuring a common CMS system. Last week, we installed and configured a minimum
provides developers with AppEngine, developers can use Python, Java, and other languages on their platforms to develop software and services, therefore, they provide developers with "platform-as-a-service". Google built its own big cloud infrastructure based on GFS, BigTable, and MapReduce, they provide "infrastructure as a service" for their internal staff. These are three different types of clouds.

different types of clouds.
OpenNebula is an open-source basic cloud computing management tool that allows administrators to centrally deploy, create, allocate, and manage a large number of virtual machines in the data center, enterprise data centers can use this tool to build their own private clouds and provide IaaS services internally. Similar open-source products include OpenStack, CloudStack, Eucalyptus, and openQRM. The following installation pr
Last time we introduced how to create a Windows Image for OpenNebula. Of course Ubuntu is indispensable. The steps for creating a Ubuntu image for OpenNebula are similar to those for creating a Windows Image. The following are the specific steps:
First download the required ubuntu version:
$ Wget http://releases.ubuntu.com/11.10/ubuntu-11.10-server-amd64.iso
Create a 10 GB hard disk in raw format ):
$ Kvm-i
