Thank you Cascardo!!! It seems that OVS workd now. I was told that the tap module is integrated within FreeBSD 10.1 and so i was convinced that the module was already loaded in the kernel, incorporated with in the kernal. I see now that thats not true! Im still quite new to these things so they are not really clear to me yet.

Are you running OVS in *BSD? Which BSD? Why don't you have /dev/tap on your
system? Try loading if_tap with kldload if_tap. That works on FreeBSD, not sure
on other systems.
