You could try this: (1) install hsflowd from host-sflow.sf.net (2) edit /etc/hsflowd.conf to turn off DNS-SD and configure the collector(s) (3) start both hsflowd and sflowovsd
Assuming that works (please tell me if it doesn't), you can look at the source code to sflowovsd, or just turn up it's log-level. It issues the ovs-vsctl commands to configure sFlow on all bridges, and keeps it in sync with the hsflowd config.
