Bug Description

When using the all in one profile with iSCSI-backed Cinder, three parameters appear to be missing from nova.conf. These are:

iscsi_ip_address=2.6.1.2
volume_group = cinder-volumes
volume_name_template = volume-%s

Without these directives, volumes can be created but can't be successfully attached to instances.

This problem affects only iscsi-backed cinder deployment scenarios: when using the Ceph backend everything appears to be configured properly.

Debugging note: Don noted that these directives are also missing in a vanilla non-AIO setup, but that volumes can be successfully attached in non-AIO setups.

Debugging note 2: Mark also verified that adding these directives does make AIO setups functional.

The more I look at this, the less I'm convinced that these parameters are actually necessary (though I don't yet know what the root cause of iscsi issues are). I'll re-examine in havana.
