Open Stack

I'm trying my newly installed Openstack system and I'm getting
problem in starting my first instance.

Cleaning up all the logs for irrelevant stuff, I see:

The web GUI say (this might be from another test, but I always
get the same):

----- s n i p -----
Error: Failed to perform requested operation on instance
"jessie-test", the instance has an error status: Please try again
later [Error: Build of instance a4e1deaa-cdf0-4fc7-8c54-579868c962c3
aborted: Block Device Mapping is Invalid.].

I can see nothing relevant in this that would make it fail!
The only thing that bought my eye was that it isn't removing
the iSCSI target, because there isn't one..

This is (most of) my cinder.conf file:

----- s n i p -----
[DEFAULT]
my_ip = 10.0.4.1
storage_availability_zone = nova
default_availability_zone = nova
enabled_backends = lvm
iscsi_target_prefix = iqn.2010-10.org.openstack:
iscsi_ip_address = $my_ip
iscsi_port = 3260
iscsi_iotype = blockio
iscsi_write_cache = on
volume_group = blade_center
scheduler_driver = cinder.scheduler.filter_scheduler.FilterScheduler

[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = blade_center
iscsi_protocol = iscsi
iscsi_helper = tgtadm
----- s n i p -----


PS. Creating the instance from an already existing, empty
    volume, didn't work either. Same message, and even less
    information in the log.
