The other datasources that are turned on by default will generally quickly have a definitive answer as to if have have data to use, and exit if not. The EC2 datasource (because of issues in the EC2 platform, many of which are historical at this point), does not exit quickly. It sits and polls for I think about 90 seconds. Because of that, its not enabled by default. However, when you install cloud-init in ubuntu, it does a very quick check for the EC2 metadata service (up to a 5 second timeout). If it finds a hit, it will configure the datasource on. So, I suspect that your problem is that the instance doesn't actually have access to a functional Ec2 datasource. You can check this by doing something like: ec2metadata --instance-id or curl http://169.254.169.254/2009-04-04/meta-data/instance-id > There is no DataSourceEC2. > > I set datasource_list: ["NoCloud", "ConfigDrive", "OVF", "MAAS", "Ec2"]. > > But I can't get anything better. > > The version of cloud-init is 0.6.3-0ubuntu1.5 /var/log/cloud-init.log will have debug information. Take a look there and see if you find any WARN messages. console output (nova console-log) is also likely useful. > -- Mailing list: https://launchpad.net/~cloud-init Post to : [email protected] Unsubscribe : https://launchpad.net/~cloud-init More help : https://help.launchpad.net/ListHelp
