<title>Configure the Image Service</title>
<para>The OpenStack Image Service enables users to discover,
register, and retrieve virtual machine images. Also known as the
glance project, the Image Service offers a <glossterm
baseform="RESTful">REST</glossterm> API that enables you to
query virtual machine image metadata and retrieve an actual image.
You can store virtual machine images made available through the
Image Service in a variety of locations from simple file systems
to object-storage systems like OpenStack Object Storage.</para>
<important>
<para>For simplicity, this guide configures the Image Service to
use the <literal>file</literal> back end. This means that images
uploaded to the Image Service are stored in a directory on the
same system that hosts the service. By default, this directory
is <filename>/var/lib/glance/images/</filename>.</para>
<para>Before you proceed, ensure that the system has sufficient
space available in this directory to store virtual machine
images and snapshots. At an absolute minimum, several gigabytes
of space should be available for use by the Image Service in a
proof of concept deployment. To see requirements for other back
ends, see <link
