Also - xenial containers are getting IPv4 address just fine.

Here is the output of "systemctl status systemd-networkd" on a bionic 
container launched yesterday, with working DHCP (it's also getting IPv4 
after restart etc.):

Here is the output of "systemctl status systemd-networkd" on a bionic 
container launched today - DHCPv4 is not working (I can get IPv4 there 
by running "dhclient eth0" manually, but that's not how it should work):

# systemctl status systemd-networkd
