Open Stack

Hello Mike,

what version of openstack ?
is the instance booting from ephemeral disk or booting from cinder volume ?

When you boot from volume, that will be the root disk of your
instance. The user could have clicked on "Delete Volume on Instance
Delete". It can be selected when creating a new instance.
