Open Stack

Hello Andrew,

as we could find in the notification system wiki 
<http://wiki.openstack.org/NotificationSystem>, we had to add the flag 
(--notification_driver=nova.notifier.rabbit_notifier) in all modules 
configuration ( /etc/nova/nova-network.conf, nova-compute.conf, 
nova-volume.conf). And restart them.

Then you can consume from the exchange name "nova" (in the rabbitmq 
server) the create/delete events. You can see the following example from 
my system:

{
  "_context_roles": [],
  "_context_request_id": "80ad9bd1-b68d-4484-be3f-6525b2f57b8f",
  "event_type": "compute.instance.create",
  "timestamp": "2012-01-13 11:39:55.946786",
  "_context_auth_token": null,
  "_context_user_id": null,
  "payload": {
  		"display_name": "one instance",
  		"created_at": "2012-01-13 11:39:52",
  		"instance_type_id": 2,
  		"instance_id": 14,
  		"instance_type": "m1.tiny",
  		"image_ref": "9",
  		"user_id": "admin",
  		"project_id": "2",
  		"launched_at": ""
  		},
"_context_read_deleted": false,
"priority": "INFO",
"_context_strategy": "noauth",
"_context_is_admin": true,
"_context_project_id": null,
"_context_timestamp": "2012-01-13T11:39:55.946820",
"publisher_id": "compute.nova-controller",
"message_id": "3dc192a1-c263-46d4-bde1-94406978517f",
"_context_remote_address": null
}

This is what I have found for the moment in the Diablo release.
