XIO.py is not for the XtremIO driver. It should be cinder/volume/drivers/EMC/xtremio.py.

I am seeing the error below in cinder-volume.log which indicates that the driver can not be found upon load. I think I am missing something very simple here. I am not sure where XtremIOIscsiDriver Class is defined. Can someone point me in the right direction?
