Bob, They could do extra deduction/guessing work to infer that, but it's a valid piece of metadata from the base image, so I'm concerned why there's so much discussion about exposing it? Seems like a provider could have a reason for exposing any number of metadata bits in the Store for their implementation needs. In addition, it assumes that any scenario where there is some unpartitioned space, the intent is to partition it; but the real desire is to determine that based on the image metadata (or API parameter).
Pardon me not having a lot of history on this process in the past.

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
