Hi Ivan,
please do the following:

1. attach a volume to vm and see that it works.

2. configure the cinder to work with ISER driver:
      a. in /etc/cinder/cinder.conf change or add -
       [DEFAULT]
        volume_driver=cinder.volume.drivers.lvm.LVMISERDriver

       b. in /etc/tgt/conf.d/cinder.conf uncomment the line
           include /etc/cinder/volumes/*

3. try to attach a volume and you'll get an error message.
