Description

Using devstack

Nova API not returning FloatingIPApi even though the ExtensionApi was listing "os-floating-ips".

Upon inspection, it is found out that the namespace for this extension is changed to a fake xml.

Ex: Extension

{id=os-floating-ips, name=FloatingIps, links=[], namespace=http://docs.openstack.org/compute/ext/fake_xml, alias=os-floating-ips, updated=Tue Dec 02 16:00:00 PST 2014, description=Floating IPs support.}

(notice fake_xml in the namespace URI)

However, org.jclouds.openstack.nova.v2_0.extensions.ExtensionNamespaces is listing it with the previous namespace:

//Floating IPs support
public static final String FLOATING_IPS = "http://docs.openstack.org/ext/floating_ips/api/v1.1";

Similar issue: http://stackoverflow.com/questions/31417247/jcloud-nova-unable-to-find-floating-ip-pool-extension

https://github.com/jclouds/jclouds/pull/813

Relevant comment from /opt/stack/nova/api/openstack/compute/extension_info.py :

1. V2.1 does not support XML but we need to keep an entry in the # /extensions information returned to the user for backwards # compatibility FAKE_XML_URL = "http://docs.openstack.org/compute/ext/fake_xml"

After changing the extension namespace in ExtensionNamespaces.java, I was able to make it work.
//Floating IPs support
//public static final String FLOATING_IPS = "http://docs.openstack.org/ext/floating_ips/api/v1.1";
public static final String FLOATING_IPS = "http://docs.openstack.org/compute/ext/fake_xml";

All extensions are returning the fake xml namespace.
So, all of them would fail lookup.
