The status being DOWN is an issue. That means either the port binding
failed because the host_id was not set on the port that matches the
hostname where the openvswitch agent is running, or the openvswitch agent
failed to identify the port from the container that was plugged in.
So there are two things. First do a port-show on that port with admin
credentials so you can see if binding:host_id is set to the hostname of the
node the container is on.
Second, I assume veth_h0 is the connection to the container? If that's the
case, you will need to add the external ID to OVSDB that indicates the
Neutron port it corresponds to. Here is an example command of how to add a
port in a way that the openvswitch agent can correctly wire it up.
Apologies for it being so hacky, it's just a quick script I had to test
Neutron agent wiring without using VMs.
port_body=$(neutron port-show $PORT_UUID)
port_id=$(echo "$port_body" | grep "| id" | awk '{ print $4 }')
port_mac=$(echo "$port_body" | grep "| mac_address" | awk '{ print $4 }')
port_name=${port_id:0:11}
port_name="tap${port_name}"
sudo ovs-vsctl --timeout=120 -- --if-exists del-port $port_name -- add-port
br-int $port_name -- set Interface $port_name
external-ids:iface-id=$port_id external-ids:iface-status=active
external-ids:attached-mac=$port_mac type=internal
The port_name may not need to be changed to match the partial port UUID
format, but there used to be old code that depended on that name so it
might be safest to first start with making your veth pair name match that
format if you can.
The giveaway is that your veth_h0 port is missing a tag on br-int. If it
doesn't have a tag (or if it has a tag of 4095), that means the openvswitch
agent hasn't correctly wired it.
