With the new Ubuntu 14.04 VM, we switched to using Wireshark 1.11.3 that has native OF parsing support. You don’t need a separate dissector anymore. Can you upgrade your wireshark to that version using these instructions?
sudo apt-get -y remove wireshark
sudo apt-get -y install libgtk-3-dev libqt4-dev flex bison
tar xvfj wireshark-1.11.3.tar.bz2
sudo make install
sudo echo “/usr/local/lib” >> /etc/ld.so.conf
