After attempting this on a KVM instance I was able to get past the
error. Ran into other issues, but can confirm that the Xenial LXD
container was unable to successfully create zfs due to the lack of
/dev/zfs.

Therefore this test of LXD ZFS backends will need to be done in KVM.

Closing as invalid.

Title:
  zfs backed lxd fails with missing /dev/zfs

Status in cloud-init:
  Invalid

Bug description:
  [description]
  While using a 16.04 (Xenial) lxd cloud image, trying to setup lxd backed by zfs fails to create due to a missing /dev/zfs

  [cloud-config]
  #cloud-config
  lxd:
    init:
      storage_backend: zfs
      storage_pool: lxd

  [steps to reproduce]
  Image used: b9cba741ef62 ubuntu 16.04 LTS amd64 (release) (20161115)

  lxc init ubuntu:xenial/amd64 xenial
  lxc config set xenial user.user-data - < cloud-config.yaml
  lxc start xenial

  [actual result]

  root@xenial-lxd:~# ls /proc/self/mounts

  [expected result]
  I would have expected zfs to be setup with a pool named 'lxd' and cloud-init to complete successfully.
