I am having the same problem on Kubuntu 16.04 machine, not in a VM.

In syslog:

ifconfig would show an inet6 address, but no inet address (IPv4).

I am able to recover by plugging the network cable out and then back in.

Also, I can recover by:
   sudo ifconfig enp3s0 down
   sudo ifconfig ens3s0 up

I have tried two different NICs.

After calling two ifconfig lines above, syslog has [see attached file].
