neutron-ovs-cleanup service runs earlier than ovsdb-server sometimes.
then, neutron-ovs-cleanup service's status remains failed
with below error msg
"ProcessExecutionError: Exit code: 1; Stdin: ; Stdout: ; Stderr: ovs-
vsctl: unix:/var/run/openvswitch/db.sock: database connection failed (No
such file or directory)"
that is fine for booting.
but.
If someday upgrade pkgs related to neutron, it runs neutron-ovs-cleanup
again because it is not in active status.
eventually, neutron-ovs-cleanup deletes all ports on running compute
nodes.

[Test Case]
1. deploy openstack env
2. run below scripts to add many ports
#!/bin/bash
for i in {0..1000}
do
- juju ssh nova-compute/0 "sudo ip link add dummy$i type dummy;sudo ip link
set name t-test$i dev dummy$i;sudo ovs-vsctl add-port br-int t-test$i";
+ juju ssh nova-compute/0 "sudo ip link add dummy$i type dummy;sudo ip link
set name t-test$i dev dummy$i;sudo ovs-vsctl add-port br-int t-test$i";
done
3. systemctl list-units --failed
- check if there is failed neutron-ovs-cleanup service
[Regression]
Changes dependency on
debian/neutron-openvswitch-agent.neutron-ovs-cleanup.service.in
need to reboot if this patch is affected. If this symptom is not affected
your env. no need to reboot.
