How reproducible:


Steps to Reproduce:
1. Install all the openstack services except cinder with packstack.
2. Install the Cinder manually and configure it according to: http://docs.openstack.org/grizzly/openstack-compute/install/apt/content/cinder-install.html
3. Install and configure a remote TGT server and configure the storage setup according to the same manual.

Actual results:
Error: cinder can't locate the cinder-volumes

Expected results:
an AIO openstack server manages its volumes remotely.
