Compute relies on an external image service to store virtual machine images and maintain a catalog of available images. Compute is configured by default to use the OpenStack Image service (Glance), which is the only currently supported image service.
If your installation requires the use of euca2ools for registering
new images, you will need to run the nova-objectstore service.
This service provides an Amazon S3 frontend for Glance, which is needed
because euca2ools can only upload images to an S3-compatible image
store.
