BATMAN V chooses routes based on link throughput. If the throughput drops 
below a certain value the route is dropped. As you can imagine, a throughput 
of 0.1 is pretty close to non-usable.

BATMAN V attempts to auto-detect the throughput using various methods which 
does not work in a virtualized environment. I suggest you go with the per-
interace /sys/class/net/<iface>/batman-adv/throughput_override setting.

Kind regards,
Marek Lindner
