Fixed In Version:
Doc Type: Bug Fix
Doc Text:
Cause: A bug in Cisco ACI's neutron implementation, present in RHOSP16, causes the query for subnets belonging to a given network to return unexpected results. Consequence: The OpenStack cluster-api-provider could potentially try to provision instances with duplicated ports on the same subnet, leading to a failed provisioning. Fix: Add additional filtering in the OpenStack cluster-api-provider to ensure there is no more than one port per subnet. Result: It is now possible to deploy OCP on RHOSP16 with Cisco ACI.
