On the other hand we end up with stuff like only being able to add 29 virtio-blk devices to a single guest. As best as I can tell, this comes from PCINo, this comes from us being too clever for our own good and not following the way hardware does it. All modern systems keep disks on their own dedicated bus. In virtio-blk, we have a 1-1 relationship between disks and PCI devices. That's a perfect example of what happens when we try to "improve" things.
Comparing (from personal experience) the complexity of the Windows drivers for Xen and virtio shows that it's not a bad idea at all.
