def _blockdevicevolume_from_dataset_id(dataset_id, size, attached_to=None):
"""
Create a new ``BlockDeviceVolume`` with a ``blockdevice_id`` derived
from the given ``dataset_id``.
This is for convenience of implementation of the loopback backend (to
avoid needing a separate data store for mapping dataset ids to block
device ids and back again).
Parameters accepted have the same meaning as the attributes of
``BlockDeviceVolume``.
