Hi Ben,

Indeed having the 'ofdatapath' module loaded was stopping OpenVSwitch from
getting loaded.
The 'dmesg' displayed the following msg

'openvswitch_mod: exports duplicate symbol dp_ioctl_hook (owned by
ofdatapath)'

once I unloaded 'ofdatapath', I was able to load openVswitch.

Thanks,
Prateek
