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:// 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! :-)
