OpenStack-on-KVM

This is a guide for setting up a OpenStack cloud using Ubuntu virtual machines running on a KVM host. The setup covers different sections from spinning up Controller Node, Compute Node, Networking, Object Storage, Block Storage, and ensuring seemless communication within different components.

What is OpenStack?

OpenStack is an open-source cloud computing platform for public and private clouds, that controls large pools of compute, network and storage resources, and allows on-demand provisioning of virtual resources through a dashboard (Horizon), command-line tools, or RESTsul APIs.

Nodes in OpenStack

  1. Controller Node
  2. Compute Node
  3. Networking Node
  4. Object Storage Node:
  5. Block Storage Node:

Detail information on nodes is found HERE

Prerequisites

  • Basic knowledge of Linux system administration.
  • Knowledge of setting up and operating KVM (Kernel-based Virtual Machine).
  • A host machine with atleast 16GB RAM and 500GB storage.
  • Ubuntu 22.04.4 LTS installed on all nodes.

Setting Up KVM on Ubuntu 20.04 Desktop

KVM, a virtualization module in the Linux kernel that leverages on modern hardware virtualization extensions such as Intel VT-x and AMD-V.

To check if processor’s virtualization extensions are enable, execute;

egrep -c '(vmx|svm)' /proc/cpuinfo
