"list_nodes" on Eucalytus forces a "500 Internal Server Error"
--------------------------------------------------------------
Key: LIBCLOUD-105
URL: https://issues.apache.org/jira/browse/LIBCLOUD-105
Project: Libcloud
Issue Type: Bug
Components: Core
Affects Versions: 0.5.2
Environment: Eucalyptus 1.6, Python 2.7.1, Ubuntu 11.04
Reporter: Rick Bross
Fix For: 0.5.2
Note that in the debug log below, when calling "list_nodes" the
"DescribeInstances" call is successful. But "list_nodes" then goes on to do an
additional (and unnecessary?) "DescribeAddresse" call which causes the error.
CODE:
logfile = open('/home/user/lc.log', "a")
enable_debug(logfile)
EC2_ACCESS_ID = 'WKy3rMzOWPouVOxK1p3Ar1C2uRBwa2FBXnCw'
EC2_SECRET_KEY = 'QhVkQMPZXd6i6qVH8tkIEqGmdVGkk1cuzJEgg'
EUCDriver = get_driver(Provider.EUCALYPTUS)
conn = EUCDriver(EC2_ACCESS_ID, secret=EC2_SECRET_KEY, host="192.168.0.170",
secure=False, port=8773, path="/services/Eucalyptus")
# This should iterate over driver types and create a generic list of nodes with
required fields
nodes = []
nodes += conn.list_nodes()
OUTPUT:
./cloud_list_instances_lc
