I'm not sure I understand why the user might want to access the disk_config value from within the guest? 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 ? -- ----------------------------- Navneet Kumar Application Developer Thoughtworks India Mob: +91 9686577076 -------------- next part -------------- An HTML attachment was scrubbed...
