I'm one of the maintainers for nova-lxd, so hopefully can get you up and
running.
In order for nova-lxd to be configured in nova, the /etc/nova-compute.conf
needs to contain the lines:
[DEFAULT]
compute_driver = nova_lxd.nova.virt.lxd.LXDDriver
This little 'fact' is hidden away in the "nova-compute-lxd" debian package,
unfortunately.
You'll also need to configure an [lxd] section in nova.conf to control the
storage pool in LXD for containers to use when launching instances.
[lxd]
allow_live_migration = True
pool = {{ storage_pool }}
The storage pool will need to be set up separately in lxd.

However, an 'easy' way to test OpenStack with nova-lxd, is to use charms.
We have a number of bundles that work with Juju. For example we have a
deployable bundle for xenial and queens at https://github.com/
openstack-charmers/openstack-bundles/tree/master/development/openstack-lxd-
xenial-queens which also has some (hopefully) useful instructions on how to
get it going.
Note the instructions say you have to use MaaS, but you should be able to
adjust using it to the hardware you are using.
As an alternative, the openstack-ansible project also supports nova-lxd,
but I don't have any experience with that.
Do come back if you have any further questions; do let me know how you get
on.
Best regards
Alex.
