OpenNebula has enhanced the Amazon EC2 and EBS API implementation exposed by the econe-server. The econe-server is a component on top of the OpenNebula core that translates Amazon API calls into OpenNebula actions, therefore a user will be able to interact with an OpenNebula cloud using any of the available EC2 clients or tool such as euca2ools, ElasticFox to interact with the econe-server.
Now instance types are based on OpenNebula templates instead of files. Users can create different base templates from Sunstone or the CLI and then make them available as instance types for users interacting with OpenNebula through the EC2 interface. These templates will be merged with the information provided by the user (i.e., AMI, user data, keypairs…) when a new instance is created. This allows us to use restricted attributes inside the templates or set permissions like any other OpenNebula resource. The describe functions have also been improved , for example users can query any of the resource pools providing a list of IDs, and now the describe-instances response includes instances that have been terminated recently.
