Your problem is not OVN, but kernel. If you want to use geneve tunnels,
you need to re-build your kernel enabling the CONFIG_GENEVE and the
corresponding CONFIG_OPENVSWITCH_GENEVE.
At the same time, your kernel seems to support vxlan, so you may configure
OVN to use that instead. It has its limitations, but I assume you're
not building a large cluster, so vxlan should be perfectly fine for your
use case. To do that, on each node run:
ovs-vsctl set Open_vSwitch . external-ids:ovn-encap-type=vxlan
After that you should have vxlan tunnels created instead of geneve.
