Hi Iban,
you are running xen (just the software) not xenserver (ad hoc linux
distribution).
Xenserver is a linux distribution based on CentOS.
You cannot recompile the kernel by your-own (... well, you can do, but
it's not a good idea).
And you should not install rpm by your-own (... but, i'm gonna do this).
Then I'm stuck with some plugin and just some rpm compatible with kernel
3.10.0-514.6.1.el7.x86_64
However I found a way to install more or less the Ceph Client.
I have forked the plugin of https://github.com/rposudnevskiy/RBDSR
<https://github.com/rposudnevskiy/RBDSR> It seems the most update.
Here you can find my findings and updates:
https://github.com/phoenixweb/RBDSR
However at the moment I'm stuck with a kernel unsupported feature. :(
Let's see if I can let this work.
Thanks for your sharings

Dear all,
even if Ceph should be officially supported by Xen since 4 years.

<https://ceph.com/geen-categorie/xenserver-support-for-rbd/>
rbd is supported on libvirt 1.3.2, but It has to be recompiled the
ii libvirt-bin 1.3.2-0~15.10~XXXX amd64 programs for
the libvirt library
ii libvirt0:amd64 1.3.2-0~15.10~XXXX amd64 library for
interfacing with different virtualization systems
Still there is no support yet.
At this point there are only some self-made plugin and solution
around.
Here some:

<https://github.com/mstarikov/rbdsr>
* https://github.com/FlorianHeigl/xen-ceph-rbd
<https://github.com/FlorianHeigl/xen-ceph-rbd>
Nobody know how much they are compatible or if they are gonna to
break Xen the next update.
The ugly truth is that XEN is not still able to fully support Ceph
and we can only pray that one of the plugin above will not destroy
our precious data or VDI.
Does anybody had some experience with the plugin above?
Which one you'll reccomend?
Is there any good installation guide to let this work correctly?
Can I just install Ceph with ceph-deploy or do I have to unlock
repos on the xenserver and instal it manuall, Thanks for any kind
of support.
Attaching volumes from openstack portal (or using cinder volume
manager), has been working fine since 6 months ago, but I do not know
what will happen on next updates
Regards,
Max
