    CORE Network Emulator does have a Docker Service that I contributed and wrote an article about. The initial version that is in 4.8 is mostly broken but I have fixed and improved it. A pull request is on GitHub.  
  
    The service allows you to tag Docker Images with 'core' and then they appear as an option in the services settings. You must select the Docker image which starts the docker service in the container. You then select the container or containers that you want to run in that node. It scales quite well and I have had over 2000 nodes on my 16Gb machine.  
  
    You mentioned OVS as well. This is not yet built in to CORE but can be used manually. I just answered a question on the CORE mailing list on this. It gives a brief overview of switching out a standard CORE switch(bridge) with OVS. Text reproduced below if it is useful:
