I've tried XenServer open source release with the ceph hack via libvirt about a year ago. This was working okay for the PoC, however, i've not really had the chance to run any stress tests or benchmarks, etc. Just created a few quick vms and quick dd, etc. It was working okay, but this is not production ready nor supported by Citrix.
Since then, I've not seen many updates about XenServer + Ceph integration. It would be nice to have ceph support in commercial hypervisor platforms such as XenServer and VMWare, but I guess enterprises do not think that ceph is ready for prime time yet. I've been using ceph for a few years now and it has improved dramatically over the period. A bunch of new features are now supported, the community is fantastic! However, I did have several issues with ceph which caused downtime to my infrastructure, which was a set back. I hope that over the next couple of years the redhat/inktank/ceph community teams will concentrate more on testing and stability of ceph rather than creating new bells and whistles.
