Running ONOS v 2.2.2 and mininet v 2.2.2 on Ubuntu 20.04, on a qemu based
virtual machine.
ONOS will not talk to the OpenVswitch using OpenFlow protocol. ONOS shows
the error:

However if I run:
sudo mn --controller=remote,ip=127.0.0.1
--switch=default,protocols=OpenFlow10 --topo tree,2,2
Everything works, If I add any additional OpenFlow protocols things start
to break.
