To me it's more than that: today i can use it to minimally boot test various 
native bzImages just by typing:

	kvm run ./bzImage

this will get me past most of the kernel init, up to the point where it would 
try to mount user-space. ( That's rather powerful to me personally, as i 
introduce most of my bugs to these stages of kernel bootup - and as a kernel 
developer i'm not alone there ;-)

I would be sad if i were forced to compile in some sort of paravirt support, 
just to be able to boot-test random native kernel images.

Really, if you check the code, serial console and timer support is not a big 
deal complexity-wise and it is rather useful:

  git pull git://github.com/penberg/linux-kvm master

So i think up to a point hardware emulation is both fun to implement (it's fun 
to be on the receiving end of hw calls, for a change) and a no-brainer to have 
from a usability POV. How far it wants to go we'll see! :-)

Thanks,
