An important point often emerging from interaction with users on IRC is mostly about Ceph.

Users sometimes ask to improve the operating guide with some Ceph basic troubleshooting on MOS.

I suggest also to significantly expand the part explaining Ceph in the planning guide and add some advices, like that with Ceph storage, raw images is reccomended, and why that.

An option in the settings that is not covered at all is "Use qcow2 format for images". It's important to add some notes, because the checkbox's label is confusing users.
