Hi, these patches (2 and 3) add storage volumes support for the Openstack driver. This relies on getting the latest version of the Openstack rubygem - 1.0.7 which is currently available.
More info/write-up about how/why when adding this functionality in both the gem and deltacloud is at http://mariosandreou.com/deltacloud/cloud_API/2012/11/19/deltacloud-openstack-driver-volumes.html marios
