It might be a better idea to use upstream kernel sources as basis. The KVM 
snapshots are rather deprecated FWIW.

Is the code to leverage Luvally vastly different from the accessors for KVM? 
Maybe it'd be enough to have a wrapper for kvm_ioctl() that sends ioctls off to 
Luvally instead of KVM to make the existing infrastructure work. That way 
upstream support should be a no-brainer and you get all the upstream qemu work 
for free.

Also, this would finally make the windows builds more useful again.
