Hi, for us these lost packets do not happen during normal operations and are always a sign of trouble. We have hit them a few when we received a large amount of packets that where send to userspace and ran into resubmit limits. The large amount of these and their processing time seem to have prevented vswitchd from processing all of these packets fast enough.
So i would generally consider them as pointer to some kind of issue.
