I'm not sure I understand why the user might want to access the disk_config value from within the guest?
I have this same feeling. It really has no bearing on the guest once it's running. It's has an effect on API calls and is readily available in that context.
This seems to be something they could infer from the partition structure - i.e. if the whole drive is partitioned then disk_config was AUTO when the instance was created.

To get any metadata/userdata of the instance a config drive ( [[http://docs.openstack.org/trunk/openstack-compute/admin/content/config-drive.html]] ) can be attached to the instance during boot-up.So disk_drive information can also be included in the config drive. Should we include this value in the config drive and xen store as well ?
Do you have a use case for this what would help explain why this is useful?
