Re: [ovirt-users] OVS error logs after upgrade to 4.2

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-c...) which gathers all the required logs for us to investigate this issue. Thanks for reporting this issue!
