The LXD team is very excited to announce the release of MicroCloud 1.1!

This is the first release of MicroCloud. It is not an LTS release so we have started with version 1.1.

MicroCloud is the easiest way to get a fully highly available LXD cluster up and running.

This initial release brings together the work of the LXD, MicroCeph and MicroOVN teams.

MicroCloud automatically configures LXD, Ceph, and OVN across a set of servers.

Is there a way to generate the preseed file for microcloud from an interactive session like how it’s able in lxd?

Is there a way to generate it later?

@masnax @mionaalex is this something that is possible at the moment? If not should we add support for it?
