Virtualisation

VirtualBox

VirtualBox config;

  • Enable host Linux modules: vboxnetflt and vboxnetadp
  • Enable host-only adapter 'virtualbox0' in VB Preferences > Network if not previously enabled, then select in guest preferences
  • Keep VM names lowercase and no spaces for easier command-line stuff

Install guest additions for mouse, etc.

Provisioning VirtualBoxes for local dev work;

Vargrant

  • Vagrant uses Oracle’s VirtualBox to build configurable, lightweight, and portable virtual machines dynamically. The first couple pages serve to introduce you to Vagrant and what it has to offer while the rest of the guide is a technical walkthrough for building a fully functional web development environment. The getting started guide concludes by explaining how to package the newly created vagrant environment so other developers can get up and running in just a couple commands.
vagrant package --vagrantfile Vagrantfile.pkg --include README.txt
  stored in ~/.vagrant.d/boxes
vagrant box add lucid32 http://files.vagrantup.com/lucid32.box
vagrant box remove lucid32
vagrant box list
  • Veewee is a tool for easily (and repeatedly) building custom Vagrant base boxes, KVMs, and virtual machine images.

Xen

  • Xen Hypervisor is an open source virtualization platform that powers the world's largest clouds in production and is the foundation of many commercial products. Xen powers public clouds such as Amazon Web Services, Rackspace Public Cloud and many others. Examples of Xen based server products include Huawei UVP, Oracle VM and XenServer. Examples of client products and appliances include QubesOS, XenClient and Netscaler. Xen is 9 years old, mature and its stability and versatility is second to none.

KVM

  • KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko. KVM also requires a modified QEMU although work is underway to get the required changes upstream. Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images. Each virtual machine has private virtualized hardware: a network card, disk, graphics adapter, etc.

VServer

  • Linux-VServer provides virtualization for GNU/Linux systems. This is accomplished by kernel level isolation. It allows to run multiple virtual units at once. Those units are sufficiently isolated to guarantee the required security, but utilize available resources efficiently, as they run on the same kernel.

etc.

Containers

Docker

  • Docker is an open-source engine which automates the deployment of applications as highly portable, self-sufficient containers which are independent of hardware, language, framework, packaging system and hosting provider.
  • dockerlite lets you run Linux apps in lightweight, isolated environments, using LXC (Linux Containers). Using BTRFS snapshots, dockerlite can save the state of a given environment in a frozen "image", and later, create more environments ("containers") out of that image.

Provision and configuration management

Puppet

apt-get install puppet puppetmaster facter rubygems puppet-module

Foreman

Chef

Salt

Other

  • Capistrano is a utility and framework for executing commands in parallel on multiple remote machines, via SSH. It uses a simple DSL (borrowed in part from Rake) that allows you to define tasks, which may be applied to machines in certain roles. It also supports tunneling connections via some gateway machine to allow operations to be performed behind VPN's and firewalls. Capistrano was originally designed to simplify and automate deployment of web applications to distributed environments, and originally came bundled with a set of tasks designed for deploying Rails applications.

  • Centmin Mod is for installation on CentOS only and written by George Liu (eva2000) with the addition of a shell menu based installer (shown on the right). Centmin Mod shell based menu allows you to do basic Nginx & PHP related management including upgrading or downgrading Nginx & PHP or setting up Nginx vhosts.

  • Nova is the project name for OpenStack Compute, a cloud computing fabric controller, the main part of an IaaS system. Individuals and organizations can use Nova to host and manage their own cloud computing systems. Nova originated as a project out of NASA Ames Research Laboratory.
