Lance,
It appears that firewalld was my issue, can you just confirm with me what
Ports should be opened for Geneve and OVN to work properly?
Hi Devin,
That's good to hear!
On the ovn-northd node, you need TCP ports 6641 and 6642 open (as mentioned in
Marcin's blog), on the ovn-controller nodes you need to allow packets with
destination UDP port 6081 (Geneve tunnels).
