The problems of disk I/O are largely a focus issue -- all this stuff
is pretty new and they focused on the network mechanisms first because
those were the ones where the competition has published the most
compelling benchmarks. The disk stuff will get tuned out and will
likely outperform network for I/O. As an example, 9P directly over
virtio beats NFS/TCP/virtio-net by 70% without cacheing or
optimization in 9P (which is usually the opposite case on
unvirtualized hardware due to cacheing and what not).
