instructions but should give you a pretty good hint.  Note the extra
variables specific for your driver.  The piece you're still going to need
is the lib/cinder_plugins which will interpret the driver settings from
your local.conf and populate cinder.conf appropriately.  Without that
you'll still get volume_driver set in the cinder.conf but none of your
options.

Also, FYI you don't have to deploy devstack with your driver enabled, just
build it normally with the default LVM, then edit /etc/cinder/cinder.conf
and put your driver parameters in.  Finally, open the screen session and
restart c-volume service and your driver will get picked up from the conf
file.
