Hi Eduardo,

May I ask for more details on what you're testing exactly? You're
running "oVirt" VMs? And do these VMs use "external" networks (i.e.
networks that were configured on the Neutron server)?

What do you mean by "private"? It does have an IP address that's
accessible from the other host, right?
