Neutron is used since nova network is not used anymore. The ha configurations depends on your number of controllers (should be 3 for ha). Instead of specifying neutron, you need to specify your network type. Vlan segmentation or tunneling (with GRE or vxlan). Vxlan is the default tunneling option as GRE was deprecated in 7 or 8 I believe. 2015-10-30 00:14:56 -0500 answered a question How does one set a list of tenants for the nova AggregateMultiTenancyIsolation filter? It should be noted that the AggregateMultiTenancyIsolation does support multiple tenant ids in the filter_tenant_id metadata. https://github.com/openstack/nova/blob/master/nova/scheduler/filters/aggregate_multitenancy_isolation.py#L47-L51 (See code here). You would specify it by doing: nova aggregate-set-metadata filter_tenant_id=tenant1uuid,tenant2uuid  The cli is not smart enough to automatically detect the duplication of settings and combine them into a comma separated list. Make sure not to put any spaces in there or you'll have to wrap the "filter_tenant_id=..." in quotes so it gets parsed correctly.
