I'm having trouble spawning an instance and I keep seeing vif_type binding errors (see https://ask.openstack.org/en/question... ). When I compare the output of ovs-vsctl show on the network node I see:

admin@net001:~$ sudo ovs-vsctl show
fc1e005e-9978-4a36-8e60-758c2a4366cf
    Bridge br-int
        fail_mode: secure
        Port "tapd3acfcd6-a7"
            tag: 4
            Interface "tapd3acfcd6-a7"
                type: internal
        Port "qr-6dfff92e-30"
            tag: 4
            Interface "qr-6dfff92e-30"
                type: internal
        Port patch-tun
            Interface patch-tun
                type: patch
                options: {peer=patch-int}
        Port br-int
            Interface br-int
                type: internal
    Bridge br-ex
        Port br-ex
            Interface br-ex
                type: internal
        Port "qg-d37a0bb0-1e"
            Interface "qg-d37a0bb0-1e"
                type: internal
        Port "eth2"
            Interface "eth2"
    Bridge br-tun
        Port patch-int
            Interface patch-int
                type: patch
                options: {peer=patch-tun}
        Port br-tun
            Interface br-tun
                type: internal
    ovs_version: "2.0.2"

where as on the compute node I the get the following with no ports defined. I can setup networks, routers successfully.

admin@compute001:/$ sudo ovs-vsctl show
37916218-40fb-4999-a353-dbf06b54c5d0
    Bridge br-int
        fail_mode: secure
        Port br-int
            Interface br-int
                type: internal
    ovs_version: "2.0.2"

My question is this what I should be seeing.

The diagram in this article shows you pretty much what you would expect to see on your compute node. The short answer is that yes, you should see ports on br-int -- this is where virtual instances are connected.

The "binding failed" errors usually indicate a problem with your neutron configuration. You probably want to look closely at the neutron openvswitch-agent log on your compute node and see if there's anything there. If you do find some errors, please update your question to include them.

If there's nothing there, you probably want to take a closer look at the neutron logs on the network host. You can reduce the number of logs you have to look through by limiting your search to lines that are contemporary with the failed nova boot attempt.
