Subject [jira] [Closed] (DTACLOUD-294) OpenNebula driver: GET /api/instances throws 'undefined method `text' for nil:NilClass' error
Date Mon, 18 Mar 2013 18:14:15 GMT

     [ https://issues.apache.org/jira/browse/DTACLOUD-294?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ronelle Landy closed DTACLOUD-294.
----------------------------------

    Resolution: Fixed

Fixed in deltacloud 1.1.2 - using Opennebula KVM sandbox:

 curl -X GET --user "un:pw" "http://localhost:3008/api/instances?format=xml"
<?xml version='1.0' encoding='utf-8' ?>
<instances>
  <instance href='http://localhost:3008/api/instances/2' id='2'>
    <name>rlandyST</name>
    <owner_id>myuser</owner_id>
    <image href='http://localhost:3008/api/images/0' id='0'></image>
    <realm href='http://localhost:3008/api/realms/ONE' id='ONE'></realm>
    <state>RUNNING</state>
    <hardware_profile href='http://localhost:3008/api/hardware_profiles/small' id='small'>
    </hardware_profile>
    <actions>
      <link href='http://localhost:3008/api/instances/2/reboot' method='post' rel='reboot'
/>
      <link href='http://localhost:3008/api/instances/2/stop' method='post' rel='stop'
/>
      <link href='http://localhost:3008/api/instances/2' method='delete' rel='destroy'
/>
    </actions>
    <public_addresses><address type='ipv4'>172.16.100.200</address></public_addresses>
    <private_addresses></private_addresses>
    <storage_volumes></storage_volumes>
  </instance>
</instances>

After instances were deleted:

>> curl -X GET --user "myuser:mypassword" "http://localhost:3008/api/instances?format=xml"
<?xml version='1.0' encoding='utf-8' ?>
<instances>
</instances>
