Cinder + LVM: No valid host found

I am setting up a single-node deployment of OpenStack Havana and have had some trouble getting the LVM backend configuration working with Cinder. I've limited my LVM testing to using a small loopfile as the backing file. I've gone through the process of creating the default physical volume/volume group while setting the appropriate configuration parameters in /etc/cinder/cinder.conf. However, when I issue a cinder create call I get the following error in /var/log/cinder/cinder-scheduler.log:

Failed to schedule_create_volume: No valid host was found.

The following is the content of /etc/cinder/cinder.conf and the results of a few LVM and cinder commands. Any help would be greatly appreciated.
