# A Heat environment file that enables DVR in the overcloud. # This works by configuring L3 and Metadata agents on the # compute nodes. resource_registry: OS::TripleO::Services::ComputeNeutronL3Agent: ../puppet/services/neutron-l3-compute-dvr.yaml OS::TripleO::Services::ComputeNeutronMetadataAgent: ../puppet/services/neutron-metadata.yaml # With DVR enabled, the Compute nodes also need the br-ex bridge to be # connected to a physical network. OS::TripleO::Compute::Net::SoftwareConfig: ../net-config-bridge.yaml # DVR requires a port on the external network for each compute node. # This will usually match the one currently in use for # OS::TripleO::Controller::Ports::ExternalPort. # Please review your network configuration before deploying to ensure that # this is appropriate. OS::TripleO::Compute::Ports::ExternalPort: ../network/ports/noop.yaml parameter_defaults: # DVR requires that the L2 population feature is enabled NeutronMechanismDrivers: ['openvswitch', 'l2population'] NeutronEnableL2Pop: 'True' # Setting NeutronEnableDVR enables distributed routing support in the # ML2 plugin and agents that support this feature NeutronEnableDVR: true # We also need to set the proper agent mode for the L3 agent. This will only # affect the agent on the controller node. NeutronL3AgentMode: 'dvr_snat' # 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. NovaReservedHostMemory: 2560
