virtio-win 0.1.15 iso missing network drivers?

[Gianluca Cecchi]

Hello,
using Fedora 15 + virt-preview, I would like to update drivers for my W7 vm.
It seems that inside the 0.1.15 iso there are no netkvm drivers for
windows 7 (both x86 and x86_64).
Any explanation for this? Where could I download updated ones?

BTW: why its version is less than the .vfd one...? 0.1.15 vs 1.1.16...
 I think this can lead to misunderstanding...
