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,
Ingo
