It's a shame you can't run pathping. However, bearing in mind that the packet loss could be in either direction, it may well be an impairment such as noise and thus not "in the VM network".

That said, as I'm sure you know, a busy VM network can discard pings when there is real data waiting. But again, the loss occurs at unexpected points such as the interconnect (7) and BBC.

That's why we'd want to see the stats and event log. Incidentally, when you post the stats, please tell us the time of day when that MTR was taken in case there are correlating events in the Event Log.
