OpenStack is the software suite used on our clouds to control hardware resources such as computers, storage and networking. It allows the creation and management of virtual machines ("VMs", or "instances"), which act like separate individual machines, by emulation in software. This allows complete control over the computing environment, from choosing an operating system to software installation and configuration. Diverse use cases are supported, from hosting websites to creating virtual clusters. More documentation on OpenStack can be found at the [http://docs.openstack.org/ OpenStack website].

This page describes how to perform common tasks encountered while working with OpenStack. It is assumed that you have already read [[Cloud Quick Start]] and understand the basic operations of launching and connecting to a VM. Most tasks can be performed using either the dashboard (as described below), the [[OpenStack Command Line Clients|OpenStack Command Line Client]], or a tool called [[Terraform]]; however, some tasks require using command line tools, for example [[#Sharing_an_image_with_another_project|sharing an image with another project]].

Images are files which contain the contents of a virtual disk. Often Images contain a base operating system used to create a volume or an ephemeral disk from which a virtual machine boots. An ephemeral disk is a virtual disk file which resides on the host (or hypervisor) where the virtual machine runs. Ephemeral disk files are destroyed when a VM is destroyed, in contrast to [[OpenStack#Working with Volumes|volumes]]. Images are portable in that they can be downloaded from the cloud, used to create a virtual machine using virtual box or similar on your laptop, and uploaded to another cloud and used to create a new virtual machine. This is not the case with volumes or ephemeral disks. Images come in a variety of formats. Some commonly encountered formats are, raw, qcow2, vmdk, and vdi.

If sharing your virtual machine images, be sure to remove sensitive information such as public/private keys, configuration files containing passwords, etc. If uploading an image created from a virtual box virtual machine to our clouds, it must have cloud-init installed and configured correctly (see openstack docs on [https://docs.openstack.org/image-guide/create-images-manually.html creating images manually] for more details).
