Merging the guest first means relying on kernel interface from an out of tree driver, which well might change before it goes in.

The graphs comparing virtio with vbus look interesting. However, they do not compare apples to apples, do they? These compare userspace virtio with kernel vbus, where for apples to apples comparison one would need to compare kernel virtio with kernel vbus.
