Using the OCCI interface you cannot define source paths for images. If you
want to use the LVM backend you have to create an Image using the OpenNebula
cli (oneimage create image_template). The image_template has to define the
SOURCE value (/dev/vg-name/lv-name) instead of the PATH. You will be able to
list these images using the GET /storage command and add them to any POST
/compute request. The tm_lvm will use the defined device specified in the

Hope this helps.
