Ok,
At moment my client use only nbd-rbd, can I use all these feature or
this is something unavoidable?
I guess it's ok.
Reading around seems that a lost feature cannot be re-enabled due to
back-compatibility with old clients.
... I guess I'll need to export and import in a new image fully feature.
Is it?

All of the features you are talking about likely require the
exclusive-lock which requires the 4.9 linux kernel. You cannot map any
RBDs that have these features enabled with any kernel older than that.
The features you can enable are layering, exclusive-lock, object-map,
and fast-diff. You cannot enable deep-flatten on any RBD ever. RBD's
can only be created with that feature. You may need to enable these in
a specific order. I believe that the order I have the features listed
is the order you need to enable them in, at least that order should work.

I read on the guide I shoulded had place in the
config|rbd_default_features|
What can I do now to enable this feature all feature of jewel on
all images?
Can I insert all the feature of jewel or is there any issue with
old kernel?
