Now if Jeff himself prefers to package RBD (RADOS), then It is true that sheepdog is not generically useful outside of block storage and specifically QEMU enabled systems (and perhaps XEN). However in the Fedora performance case, I expect sheepdog with its lower memory copy operation count and tight integration with QEMU to produce better performance results and lower cpu utilization, resulting in higher density of VMs on equivalent hardware. There is only one way to validate this speculation - integrate the various solutions into Fedora and see which has the best mix of real-world attributes.
