Thank you Rob, Nick, Just to close the thread! It wasn't a FV issue, I did the patch, edit switch.c accordingly to discard possible problems, but the problem persisted. I had an error in mininet, also I changed the orden of events in nox.json (I use pyswitch and dnsspy) and now it works. Almost everything go well, I have a OFPBRC_BUFFER_UNKNOWN (type=1 code=8) error message only when a controller connects through flowvisor I disabled all events registered in Nox and I still have the error, it seems to be produced by FV installaing the slice? Anyway, it doesn't affect the functionality. I'm just trying to avoid possible future problems related to this. Any idea?
