[Openstack] Cinder: Creating test volume fails

Hi Mike,
Try turning on debug messages in /etc/cinder/cinder.conf and restarting the
volume service.  This will log exactly what command is being issued.  Based
on this, you can try to issue the same command directly from the command
line.  This should give some clues on why the volume create is failing.
Send a reply if you're still stuck and we can dig in further.

Subject:	[Openstack] Cinder: Creating test volume fails


I've gone through archives and performed searches, etc etc and have been
unable to find a fix for this so I'm hoping someone can shed some light on
it for me here... Environment is (quite unfortunately) a desktop PC running
VMware Player with an Ubuntu 12.04 LTS VM (kernel 3.2.50-030250-virtual).
I've been successful in getting the identity service and image service both
up and running and now I'm stuck.. Here's the error, which FWIW was posted
on the cinder-install.html page under the Grizzly install docs too:

2013-08-27 13:04:27 ERROR [cinder.volume.iscsi] Failed to create iscsi

in create_iscsi_target
    raise exception.ISCSITargetCreateFailed(volume_id=vol_id)
ISCSITargetCreateFailed: Failed to create iscsi target for volume

Additional notes:
- RabbitMQ is running and can be connected to
- open-iscsi and iscsitarget are both installed/running
- already changed the tgt/conf.d/ files as ppl referenced in the comments..

Any help would be greatly appreciated.
