It looks like you can now compile Xen against a stock upstream QEMU in the 4.2 release (and this will be the default option in 4.3). In theory this should provide basic rbd support to Xen VMs. http://wiki.xen.org/wiki/QEMU_Upstream Are there any Ceph users running Xen who have tried this? Be interested in your feedback.
