Hi Ben, Thank you for the fact.
It was verified with installation of Mininet 2.1.0+ on Ubuntu 13.10 (Saucy). Open vSwitch 2.1.2 was successfully installed with NO errors but Mininet could not start the controller: ... *** Starting controller Cannot find required executable ovs-controller. Please make sure that it is installed and available in your $PATH: (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin) ... Despite the fact that OVS 2.0.1 is magically available for Ubuntu 14.04 LTS it is hoped that later version of OVS will be available soon.
