Title:
swap and ephemeral devices defined in the flavor are not created as a
block device mapping
Status in OpenStack Compute (nova):
Fix Released
Status in OpenStack Compute (nova) kilo series:
Fix Committed
Bug description:
When booting an instance specifying the swap and/or ephemeral devices,
those will be created as a block device mapping in the database
together with the image and volumes if present.
If, instead, we rely on libvirt to define the swap and ephemeral
devices later from the specified instance type, those devices won't be
added to the block device mapping list.
To be consistent and to prevent any errors when trying to guess the
device name from the existing block device mappings, we should create
a mappings for those devices if present in the instance type. We
should create them from the API layer, before validating the block
device mappings and only if no swap or ephemeral device are defined by
the user.
