# A Heat environment file that enables DVR in the overcloud. Used with Compute

|
# DVR role. Note that the network configuration is consistent with the default
|
|
# tripleo network templates so some customization is likely required for
|
|
# production deployments.

# 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.

# host networking to work with the default 'datacentre' network.
