You can load ISO images into the Image Service. You can subsequently boot an ISO image using Compute.

Procedure 7.1. To load an ISO image to an Image Service data store

Obtain the ISO image. For example, ubuntu-13.04-server-amd64.iso.
In the Image Service, run the following command:
```
$ glance image-create --name ubuntu.iso \
   --is-public True --container-format bare \
   --disk-format iso < ubuntu-13.04-server-amd64.iso
```
In this command, ubuntu.iso is the name for the ISO image after it is loaded to the Image Service, and ubuntu-13.04-server-amd64.iso is the name of the source ISO image.
Optionally, confirm the upload in Compute.
Run this command:
```
$ nova image-list
```
