      - (Floating point) Offset weight multiplier Multiplier used to weigh offset weigher. Cells with higher weight_offsets in the DB will be preferred. The weight_offset is a property of a cell stored in the database. It can be used by a deployer to have scheduling decisions favor or disfavor cells based on the setting. Possible values: * Numeric multiplier Services which consume this: * nova-cells Related options: * None

      - (Floating point) Reserve percentage Percentage of cell capacity to hold in reserve, so the minimum amount of free resource is considered to be; min_free = total * (reserve_percent / 100.0) This option affects both memory and disk utilization. The primary purpose of this reserve is to ensure some space is available for users who want to resize their instance to be larger. Note that currently once the capacity expands into this reserve space this option is ignored. Possible values: * Float percentage value Services which consume this: * nova-cells Related options: * None

      - (String) Topic This is the message queue topic that cells nodes listen on. It is used when the cells service is started up to configure the queue, and whenever an RPC call to the scheduler is made. Possible values: * cells: This is the recommended and the default value. Services which consume this: * nova-cells Related options: * None
