DVR doesn't imply the "External" networks, simply some type of connection that is being used for floating IP traffic. This patch removes the External network from the DVR role and "left overs" from environment files. It also corrects the multiple-nics version of the templates so that the ComputeDVR role is attached to the external bridge with no IP.

# 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.
