Yep. The fact that it is possible to do that doesn't imply that it is the best solution.
Oh, and btw: What was the reason why kvm paravirtualization doesn't use the vmi interface?

xen and vmware are still two very different hypervisors from the memory mangement point of view. I doubt moving the abstraction line within the linux kernel from paravirt_ops to vmi makes QA easier.
