> Glance is currently broken in jclouds-labs-openstack because it attempts to performs operations at the base URL returned in the Keystone catalog. Glance is built to run multiple versions of its API at different endpoints, which can be discovered by querying the base URL returned by Keystone. JClouds needs to perform this version negotiation in order to make Glance work.
> In 99% of cases, this last part of the url will be either "/v1" for versions 1.0 and 1.1 of the API or "/v2" for version 2.0, so one possible fix could be to simply apply a Path annotation on top of the org.jclouds.openstack.glance.v1_0.features.ImageApi specification. However, according to Mark Washenberger, the current Glance PTL, the most correct operation is to actually query for the appropriate URL for the requested version. (I'll try to pull up docs that confirm this and link them when I can to avoid this "documentation by dictator").
