Hi.
There is a solution for Ceph in XenServer. With the help of my engineer
Mark, we developed a simple patch which allows you to search and attach
RBD image on XenServer. We create LVHD over the RBD (not RBD per VDI
mapping yet), so it is far from ideal, but its a good start. The process
of creating the SR over RBD works even from XenCenter.
https://github.com/mstarikov/rbdsr
Install notes are included and its very simple. Takes you few minutes
per XenServer.
We have been running this in our Sydney Citrix lab for sometime and I
have been running this at home also. Works great. For the future, the
patch should work in the upcoming version of XenServer (Dundee) as well.
Also we are trying to push native Ceph packages in the new version and
build experimental (not official or approved yet) version of smapi which
would allow us to map RBD per VDI. But there are no details on this.
Anyway, everyone is welcome to participate in improving the patch on github.
Let me know if you have any questions.
Cheers,
Jiri

Hi lists
Is there any solution or documents that ceph as xenserver or xen backend
storage?
Not really.
There was a project to natively support Ceph (RBD) in Xenserver but that
seems to have gone nowhere.
There was also a thread last year here "RBD hard crash on kernel
3.10" (google for it) wher Shawn Edwards was working on something similar,
but that seems to have died off silently as well.
While you could of course do a NFS (some pains) or iSCSI (major pains)
head for Ceph the pains and reduced performance make it not an attractive
proposition.
