I have set up OpenStack using Kolla Ansible with OVS and OVN. On one compute node, meters are functioning correctly, but on another, I am encountering an issue. Both nodes use the system datapath, have the same kernel version, and run the same version of OVS. Despite this, the problem persists. Has anyone experienced a similar issue? What could be the root cause? For example, I have two compute nodes. One of them does not have any issues, but the other meter did not work . following compute meter does not working:
