Hi Brian,
never listen before.
However seems nice and fully featured.
The pity is that is based o KVM, which is as far as I know is a ligth
hypervisor that is not able to isolate the virtual machine properly.
Due to this is possible to frozen the hypervisor kernel from a guest
virtual machine allowing somebody to freeze all your VMs all in once.
Xen is completly isolated (of course not as light as KVM). You can
freeze a VMs but other could not be affected in anyway.
Security should not considered an option.
Thanks anyway,
Max

Hi Max,
Have you considered Proxmox at all? Nicely integrates with Ceph
storage. I moved from Xenserver longtime ago and have no regrets.
Thanks

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
<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
