[mininet-discuss] Connection with "real" hosts

Hi Bob,
I know that is better to use Mininet hosts, but my hosts are Openstack
compute nodes, I would like to use Mininet to build the Openstack data
network managed by an ODL Controller.
Moreover I can't access to the server's domain 0, because I have only the
address of the VMs (that perform as hosts and as OpenStack/ODL Controller).

I'll look for the other suggestions you gave, let me know if somethin raise
on you mind about my scenario.
