OVSDB Id Needs changing
Cloned VMs need to change the OVSDB UUID so that it can be seen by the SDN Controller i.e. avoid duplicate OVSDB Id (uuid).
Need to deal with /etc/openvswitch/conf.db
Moved it to conf.db.old and restarted VM so that it generates a new random UUID as per RFC 4122
Also needed to deal with that pesky /etc/udev/rules.d/70-persistent-net.rules
Used postman to check that OVSDB was working
