Facing the same issue but with dhcp and on ubuntu 16.04 VM. $ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 16.04.3 LTS Release: 16.04 Codename: xenial
Just after initial launch of VM, it's not accessible. /run/network/ifstate files for interfaces are locked by ifup which only gets released and dhcp probe begins when networking service is restarted. After this VM becomes accessible. $ cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them.
