Re: [ovirt-users] oVirt 4.1.1 and ovn problems

It looks like ndb is listening (netstat shows this), but not receiving anything (log is empty). This looks like a connectivity issue. Can the provider host ping the ovn host? Is firewalld/iptables disabled on both hosts? Let's make sure that OVN is working fine. I attach a short python script that checks the connection from the localhost. Please check if it can connect to ovn from localhost (just execute this on the host with ovn: "python tcp_connection_test.py" ). It should connect and print out all the OVN networks. Does this work?
