Hello
really no answer from the list ? Three weeks, two emails. Nothing so far.
I really want to use OVS for my cloud but I can't if every second day network
connectivity is lost.
Please help in debugging this issue, or let me know what I need to deliver as
information.
ovs-bug report is collected and can be shared.
cheers and thanks for any help
