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.
