The 486 flavour doesn't have CONFIG_XEN enabled and in fact upstream recently removed non-PAE 32 bit support from the hypervisor so no need there. > What about amd64?

When I added them locally I stuck the disk driver in the scsi-modules udeb (a bit arbitrarily) and the net one in nic-modules. > Depends on how/when they are used. There are needed in the same places as you would need any other network or disk driver -- so in the netboot image for net and available prior to disk detections for the second etc. > > I included virtio too, because, well, why not ;-) > > Because we're _always_ trying to save on memory usage.

Well, I guess the installer could be used under KVM as well, which is what the virtio drivers target (I'm pretty sure, don't use it myself...). Although since kvm is fully virtualised by default I guess you can install using emulated devices and switch to virtio afterwards -- it'll just mean performance is worse while installing and is an extra step admins have to go through.
