"The host implementation is in userspace - qemu, so no driver is needed in the host."
This might technically be true... but current kernels (2.6.35.x) do have options in the Virtualization section like:
Host kernel accelerator for virtio net PCI driver for virtio devices Virtio balloon driver
Does this page need updating to reflect their existence and use?
