[dev] [jira] [Commented] (LIBCLOUD-117) OpenNebula Compute Network
Description
[ https://issues.apache.org/jira/browse/LIBCLOUD-117?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13125252#comment-13125252 ]
Tomaz Muraus commented on LIBCLOUD-117:
---------------------------------------
I checked our test fixtures and it looks like "IP" is an attribute there, not a separate tag.
Which version of the OpenNebula API are you hitting?
In any case, I have commited a patch which should fix it - [r1182002|http://svn.apache.org/viewvc/libcloud/trunk/libcloud/compute/drivers/opennebula.py?view=diff&r1=1182001&r2=1182002&pathrev=1182002] (prefer "ip" attribute, if not specified, fall back to "IP" tag).
Thanks.

> Components: Compute
> Affects Versions: 0.5.2, 0.6.0
> Environment: Debian Squeeze using 0.5.2 libcloud extracted archive file.
> Reporter: Hutson Betts
> Labels: patch

> An issue exists in the way the OpenNebula driver pulls the network IP address for a compute node. It causes the driver to fail every time.
> Function Call:
> cloudProvider.connection.list_nodes()
> Exception Output:
> Traceback (most recent call last):
> File "test.py", line 65, in <module>
> nodes[cloudProvider.host] = cloudProvider.connection.list_nodes()
> File "/var/lib/service-manager/service-management-system/lib/apache-libcloud-0.5.2/libcloud/compute/drivers/opennebula.py", line 113, in list_nodes
> return self._to_nodes(self.connection.request('/compute').object)
> File "/var/lib/service-manager/service-management-system/lib/apache-libcloud-0.5.2/libcloud/compute/drivers/opennebula.py", line 188, in _to_nodes
> computes.append(self._to_node(compute))
> File "/var/lib/service-manager/service-management-system/lib/apache-libcloud-0.5.2/libcloud/compute/drivers/opennebula.py", line 200, in _to_node
> networks.append(element.attrib["ip"])
> KeyError: 'ip'
> Cause:
> for element in compute.findall("NIC"):
> networks.append(element.attrib["ip"])
> OpenNebula/OCCI Compute Definition
> <COMPUTE href="http://www.opennebula.org/compute/32">
> <ID>32</ID>

> <NIC>
> <NETWORK href="http://www.opennebula.org/network/12"/>

> <IP>192.168.0.12</IP>
> ...
> </NIC>

> </COMPUTE>
> Conclusion:
> IP address information is not an attribute. Rather it's a child element of the NIC.
> Patch:
> With patch, the NIC information is returned correctly:
> <Node: uuid=894yf9823fh9, name=one-34, state=4, public_ip=['10.2.0.5', '10.2.2.3'], provider=OpenNebula ...>
