I am using neutron 19.1 and ovn 21.09. There is a strange behavior I am
seeing on compute nodes that ovs logs shows below logs
2022-02-23T06:14:06.426Z|00226|bridge|WARN|could not open network device
tapea0dca9a-32 (No such device)

2022-02-23T06:14:06.433Z|00230|bridge|WARN|could not open network device
tap18864125-6d (No such device)
In the ovs-vsctl show I also see alot of ports with these status.
error: "could not open network device tapaeaa1749-b5 (No
error: "could not open network device tap18864125-6d (No
error: "could not open network device tap54415fc0-dd (No
I have checked in neutron port list and there is no port found for these
openstack port list --long | grep -i 18864125-6d
I have checked in database in ports table, there is also no ports there
with these ids.
mysql> select * from ports where id like '%18864125-6d%';
These ports even show on compute node even if there is no instance running
on it. Are these stale ports ? If yes, is there any tool or utility to run
audit and delete these ports ?
