You are wrong on three counts:

 - As I mentioned it in my first mail to you this is not the 
   same as 'vm run': you still have a qemu-root.img while 
   tools/kvm does not ...

   'vm run' works without having any disk image around, it just 
   uses the existing distro binaries and boots them, sharing the 
   host file system.

 - automatic, transparent host filesystem sharing is another 
   useful feature: I can copy files in/out of the virtual 
   machine using the host filesystem.

 - transparent networking is up and running straight away

But yeah, I guess if you ignore enough key tools/kvm/ features 
then you will eventually be right: it's really just the same as 
Qemu and has no place in the kernel repo ;-)
