Managing images
Image management in an OpenStack environment can be achieved using the openstack command-line tool, the Horizon dashboard, or directly via the Glance REST-based API. Images can be sourced directly from the internet or created and manipulated with tools such as virsh, virt-manager, growpart, and cloud-init. Custom image creation will be covered later in this chapter.
