It seems that adding:
After=openvswitch-switch.service
to neutron-ovs-cleanup.service will be enough to fix this bug.
As long as openvswitch-switch is not already installed at the time of
neutron-openvswitch-agent being installed, then neutron-openvswitch-
agent will cause openvswitch-switch to be installed and neutron-ovs-
cleanup should be forced to start after openvswitch-switch.
I'm not following your comment on 1630968. Is that issue related to this
change?

Bug description:
[Impact]
In code, Basically all ubuntu version could be affected.
I'm trying to do test them
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.
related logs here https://paste.ubuntu.com/p/QkkwP2vPDv/
[Test Case]
1. deploy openstack env
2. run below scripts to add many ports
#!/bin/bash
juju ssh nova-compute/0 '
sudo modprobe dummy
for i in {1..1000}
do
echo $i
sudo ip link add dummy$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.
