Try a pathping. Remember that the time it takes for a component on the network to respond (high pings) may not be slowness to and from it, but the fact that ping requests are prioritised less than actual data going through the connection. Using pathping means more will hit it, and you'll get a better mean result.

That said, i notice the biggest jump in times in your tracert is between iph.uk.goscomb.net (off the VM network) and your target address. That would suggest the issue is between those two points. Once the packet has left the VM network their influence over it is minimal.
