As described in the comment, systemd will create a broken /etc/resolv.conf link if there is no file in the base-image (as you can read in the bug, it is debated if this is a bug or a feature). The solution is to leave a dummy /etc/resolv.conf file in the image. Whatever network manager you choose (NetworkManager, glean, cloud-config, etc) will overwrite this anyway. It's just that some tools, such as dhclient, get confused with the broken symlink. This affects you if you're using glean to configure the network in a DHCP situation, for example -- dhclient won't configure nameservers and everything goes to heck.

Image building tools for OpenStack
diskimage-builder is a flexible suite of components for
building a wide-range of disk images, filesystem images and ramdisk
images for use with OpenStack.
This repository has the core functionality for building such images, both virtual and bare metal. Images are composed using elements; while fundamental elements are provided here, individual projects have the flexibility to customise the image build with their own elements.
For example:
$ DIB_RELEASE=trusty disk-image-create -o ubuntu-trusty.qcow2 vm ubuntuwill create a bootable Ubuntu Trusty based qcow2
image.
diskimage-builder is useful to anyone looking to produce
customised images for deployment into clouds. These tools are the
components of TripleO that are
responsible for building disk images. They are also used extensively to
build images for testing OpenStack itself, particularly with nodepool.
Platforms supported include Ubuntu, CentOS, RHEL and Fedora.
