Unable to start AWS EC2 instance with deltacloud

Question

I am trying to manage a EC2 cloud instance with deltacloud API through curl . With the mock driver everything works fine: deltacloudd -i mock -r 10.0.0.3

curl --user "mockuser:mockpassword" "http://10.0.0.3:3001/api/instances?format=xml"
curl -X POST --user "mockuser:mockpassword" "http://10.0.0.3:3001/api/instances/inst1/stop?format=xml"

But with EC2 I am unable to start a stopped instance: deltacloudd -i ec2 -P eu-west-1 -r 10.0.0.3 -V

curl --user "accesskey:secretaccesskey" "http://10.0.0.3:3001/api/instances?format=xml"
curl -X POST --user "accesskey:secretaccesskey" "http://10.0.0.3:3001/api/instances/i-NNNNNNNN/start?format=xml"

Returns: The required capability to execute this operation is missing

Deltacloud log output:

Listening on 10.0.0.3:3001, CTRL+C to stop
D, [2014-06-25T10:47:34.149001 #3575] DEBUG -- : New Aws::Ec2 using per_thread-connection mode
D, [2014-06-25T10:47:34.150897 #3575] DEBUG -- : Opening new HTTPS connection to ec2.eu-west-1.amazonaws.com:443
10.0.0.5 - - [25/Jun/2014 10:47:34] "GET /api/instances?format=xml HTTP/1.1" ec2 eu-west-1 200 1628 0.6204
10.0.0.5 - - [25/Jun/2014 10:48:14] "POST /api/instances/i-NNNNNNNN/start?format=xml {} HTTP/1.1" ec2 eu-west-1 412 60 0.0077

Its therefore obvious that deltacloud process GET, but not forward the POST request to AWS .

The Problem also happens even by clicking the start button at the webinterface (10.0.0.3:3001). The accesskey and secretaccesskey are working fine with python-boto.

Can anyone suggest me whats wrong?

Answer 1

The short answer is, that you can not start a stopped Amazon EC2 instance with deltacloud in the current version 1.1.3 (2013-04-17). Perhaps there will be soon a newer version, but since Red Hat reduced their support the development of deltacloud slowed down.
