Practically the only difference performance-wise between virtio and
high-end controllers is that the ring index is located in a chip
register on real hardware, and in memory for virtio (plus hardware can
ask virtio not to notify).
Real hardware assumes guest->controller traffic is cheap, which isn't
true for virtio/kvm.
