The Glance image service provides an API that we can use to discover, register, and obtain images for virtual machines. When we later use Nova compute to build a new KVM instance, the Nova service will send a request to Glance to obtain the requested image type.
In this recipe, we are going to install Glance and register a new Ubuntu image.
For this recipe, we are going to need the following things:
- An Ubuntu server with great virtualization capabilities
- Access to the internet for package installation
- A database server, a message queue, and
memcachedinstalled and configured, as described in thePreparing the host for the OpenStack deploymentrecipe
- The Keystone service we deployed in the Installing and configuring the OpenStack Keystone identity service recipe
