Yup, "make kvmconfig" does things right but I guess a general mechanism
might be preferred here :)

Look, if (at the moment) I'm going to nconfig and virt. section, I see

Virtualization
  Kernel-based Virtual Machine (KVM) support
    KVM for Intel processors support
    KVM for AMD processors support
    Audit KVM MMU
  Host kernel accelerator for virtio net (EXPERIMENTAL)

and everytime I'm here I need to remember where to search for
virtio devices I would like to include into config. Though I
expect to see in this secrion everything related to virtualization
and have a way to turn on virtio-ring and etc.

For example to enable "PCI driver for virtio devices" I need to
go to Device Drivers -> Virtio drivers, while I think it would
be great to have everything virt. related in Virtualization
section.

(note, I know how to enable all this and where to lookup for
 this entries of course, but I guess for regular users it
 would be easier to enable various virt. features if they
 are gathered in one place)
