I see that I've run "dpkg-reconfigure -p medium lxd" too late (after the container was created), and because of this eth0 was set to manual (in /etc/network/interfaces.d/): auto eth0 iface eth0 inet manual New containers have it properly set to dhcp.

A somewhat common mistake which leads to the behavior you described is when your chosen subnet doesn't match your chose DHCP range. "ps aux | grep dnsmasq" on the host would confirm if that's the case. -- Stéphane Graber Ubuntu developer http://www.ubuntu.com signature.asc Description: PGP signature ___ lxc-users mailing list lxc-users@lists.linuxcontainers.org http://lists.linuxcontainers.org/listinfo/lxc-users
