libvirt users - Aug 2015 - Windows 10 guest

I am trying to install windows 10 (dreamspark education ISO) into
qemu-kvm on Gentoo linux.

I got past the cpu problems but am stuck on the image file drivers.

The relevant xml is below.  It asks for the driver disk which I have,
but if I select a driver (either vioscsi or viostor which show as valid
it churns away for a few seconds and brings up the cant find driver
dialog and cant progress.  I've tried both the 102 and 109 RH driver
versions (Ive tried most drivers from the ISO's that shows as
compatible, usually win8 or 8.1.)  Both cdrom xml definitions work fine,
but the disk one doesn't and I cant find the magic incantation.

    </disk>

Hmmm ... downloading via windows gave a different sized file to when I
used Linux.

Its now working with the settings below and the win8.1 viostor amd64 driver.
