This is presented as a raw block device with no partition table or filesystem. Cloud aware operating system images may discover, format, and mount this device. For example the cloud-init package included in Ubuntu's stock cloud images will format this space as an ext3 filesystem and mount it on /mnt. It is important to note this a feature of the guest operating system. OpenStack only provisions the raw storage.

The following images will mount the ephemeral disk automatically since they have a cloud-init config http://docs.openstack.org/image-guide...
