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

[Mor Kalfon]

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!
