To me and Pekka that is what made Qemu unhackable.

Really, i'm not sure why you are arguing here. We are not trying to 
merge tools/qemu/ upstream. We are trying to merge a Linux-only 
utility that lives in the kernel tree today and which we are actively 
using and developing.

That's a rather bizarre argument, we were pretty happy with the 
design of the KVM host side, what we wanted to improve was user-space 
tooling.

With lguest we'd have to write a new host implementation in essence

FYI, tools/kvm/ *already* lives in the kernel tree - that is how it's 
developed and used and it also shares code with the kernel.
