Short answer is that nova-lxd does support use with Ceph, but only for
additional block devices  (I.e no boot from volume or ephemeral device
support right now).

You have highlighted a documentation gap - there are a few non obvious
things todo like ensuring that cinder creates RBD devices with a minimal
feature set to support use the the kRBD driver used for nova-lxd.  Will
look to put a howto for ceph in place shortly!
