In an email you asked further questions:
> Can you tell us the background of the host? Is it a clean newly
installed machine or vm?
My own development system upgraded to 16.04 from 15.04.
> How was lxd installed?
lxd was installed from the archive.
dpkg -l | grep lxd
ii lxd 2.0.0~rc4-0ubuntu1
amd64
> How was docker.io installed in the container?
First I got into the container `lxc exec xenial /bin/bash`
I installed docker.io with `apt-get update && apt-get install docker.io`.
Running `docker info` shows the aufs driver selected
Storage Driver: aufs
Root Dir: /var/lib/docker/aufs
Backing Filesystem: extfs
> Can you easily reproduce this with the same iso (or whatever you used)
for the host?
Yes this is still reproducible on my system. The steps are:
$ lxc launch images:ubuntu/xenial/amd64 xenial -p default -p docker
$ lxc exec xenial /bin/bash
# apt-get update && apt-get install -y docker.io
# docker info
# docker run hello-world
