I'd be more interested in enabling people to build these types of
storage systems without touching qemu.
Both sheepdog and ceph ultimately transmit I/O over a socket to a
central daemon, right?
That incurs an extra copy.
So could we not standardize a protocol for this that both sheepdog and
ceph could implement?
The protocol already exists, nbd. It doesn't support snapshotting etc.
but we could extend it.
But IMO what's needed is a plugin API for the block layer.
