Deleting broken ovs tunnels [closed]

Hello, I've been fixing my ovs_neutron_plugin.ini and now I have a couple of broken gre-* tunnels under my br-tun bridge.

I would like to delete these entries as these still causes ovs to output logs which distracts me from continuing my fix.

I've tried ovs-vsctl del-port gre-1 on both my network and compute node, however, the tunnels still return after a reboot.

Thank you for your help

Here's my current list of tunnels on my compute node

root@gold:~# ovs-vsctl show
2cfbc50b-48da-4336-ad52-95e400021f3c
    Bridge br-tun
        Port "gre-2"
            Interface "gre-2"
                type: gre
                options: {in_key=flow, local_ip="128.237.157.202", out_key=flow, remote_ip=nitrogen.club.cc.cmu.edu}
        Port br-tun
            Interface br-tun
                type: internal
        Port "gre-1"
            Interface "gre-1"
                type: gre
                options: {in_key=flow, local_ip="128.237.157.202", out_key=flow, remote_ip=gold.club.cc.cmu.edu}
        Port "gre-4"
            Interface "gre-4"
                type: gre
                options: {in_key=flow, local_ip="128.237.157.202", out_key=flow, remote_ip="128.237.157.43"}
        Port patch-int
            Interface patch-int
                type: patch
                options: {peer=patch-tun}
    Bridge "br-eth0"
        Port "phy-br-eth0"
            Interface "phy-br-eth0"
        Port "eth1"
            Interface "eth1"
        Port "br-eth0"
            Interface "br-eth0"
                type: internal
    Bridge br-int
        Port br-int
            Interface br-int
                type: internal
        Port "int-br-eth0"
            Interface "int-br-eth0"
        Port patch-tun
            Interface patch-tun
                type: patch
                options: {peer=patch-int}
        Port "tap20420387-0d"
            tag: 1
            Interface "tap20420387-0d"
    ovs_version: "1.10.2"

And here's a tunnel I want to delete

I'm afraid your only option at this time is to manually remove the offending rows from the neutron database. I think the table name is ovs_tunnel_endpoints when using the OVS plugin. Then the agents will need to be restarted.

Thank you, that worked perfectly. I just had to run `DELETE FROM ovs_tunnel_endpoints WHERE id=1` in the neutron database.
