Hello Misak, Could you please file a bug about those error messages that you receive from OVS? You can use the log collector tool (https://www.ovirt.org/ documentation/admin-guide/chap-Utilities/#the-log-collector-tool) which gathers all the required logs for us to investigate this issue.
Thanks for reporting this issue!
