+ # Enabling DVR deploys additional services to the compute nodes that through
+ # normal operation will consume memory. The amount required is roughly
+ # proportional to the number of Neutron routers that will be scheduled to
+ # that host. It is necessary to reserve memory on the compute nodes to avoid
+ # memory issues when creating instances that are connected to routed
+ # networks. The current expected consumption is 50 MB per router in addition
+ # to the base reserved amount. Deployers should refer to existing
+ # documentation, release notes, etc. for additional information on estimating
+ # an appropriate value. The provided value here is based on an estimate of 10
+ # routers and is an example value *only* and should be reviewed and modified
+ # if necessary before deploying.
