Hi,

When we try to add ephemeral disk in booting instance, as we know that it will create disk.local and the backing file in _base. Both of them are referred to the ephemeral disk. When nova reports the disk usage of compute, does it count both of them for the used disk? What I see in the resource_tracker that it calculates the instance['ephemeral_gb'].
