To delete flows I used ovs-ofctl del-flows bridge. I tried using a default deny rule and that worked, but it seems a bit hack-ish. I thought that no traffic would be processed if no flows were specified..

    One thing I've noticed is that when I use vswitchd, it uses some
    kind of default flow table in
    unix:/usr/local/var/run/openvswitch/vbr0.mgmt. I tried deleting
    the flows so that pinging from one host to another should not
    work, but pinging seems to re-create the flows. Is there a way to
    disable this?


Could you be more specific on what command you run to delete the flows? Is it possible you are just deleting the active flow, instead of the rule that is creating it? You also can look into pushing down a 'default deny'-styled rule, which has low priority, no specified fields and no actions, so any flow which doesn't match your configured flows (if any) will be dropped.
