Good bit of information about this found here...

    https://github.com/lxc/lxd/issues

Good starting points...

Keep in mind LXD 3.0 will likely change some of this information.

Another problem area - the current move of many Distros from
old network config files to Netplan config files. This change
breaks all tools used to auto generate /etc/network/interfaces
type files, so keep this in mind if you have an automated
process for mass container creation.
