Open Stack

Dear All,   I'm installing a private cloud computing environment on our lab, and we are using one physical server currently.  We have registered images from http://docs.openstack.org/developer/sahara/userdoc/vanilla_plugin.html, with version 2.4.2.  However, after we click launch cluster, it results in error, and when i check the /opt/stack/logs/screen-sahara.log, i found there is a JSON data for the ERROR message, saying that security not found, the total JSON data is as followed.-------------------------------------------------------------------------------------------------{"stack": {"parent": null, "disable_rollback": true, "description": "Data Processing Cluster by Sahara", "links": [{"href": "http://10.      0.20.250:8004/v1/fcdf1ad8529d4c96b54b52ae096e68b4/stacks/TestCluster/0c1a035e-a97c-44e6-a328-dacdaff376a5", "rel": "self"}], "stack_sta      tus_reason": "Resource CREATE failed: BadRequest: Security group 1 not found for project fcdf1ad8529d4c96b54b52ae096e68b4. (HTTP 400) (      Request-ID: req-aec2c11e-cc3d-4d80-9b44-ffb1cd3d7c06)", "stack_name": "TestCluster", "outputs": [], "stack_owner": null, "creation_time      ": "2014-11-26T23:38:07Z", "capabilities": [], "notification_topics": [], "updated_time": null, "timeout_mins": 180, "stack_status": "C      REATE_FAILED", "parameters": {"AWS::StackId": "arn:openstack:heat::fcdf1ad8529d4c96b54b52ae096e68b4:stacks/TestCluster/0c1a035e-a97c-44      e6-a328-dacdaff376a5", "AWS::Region": "ap-southeast-1", "AWS::StackName": "TestCluster"}, "id": "0c1a035e-a97c-44e6-a328-dacdaff376a5",       "template_description": "Data Processing Cluster by Sahara"}}-------------------------------------------------------------------------------------------------  And running "nova secgroup-list", the result is stack at charmander:~$ nova secgroup-list
