Hello, All!

virtio-win.iso contains two different Windows drivers.
these Windows Server 2012 R2 drivers have different hardware IDs:

\vioscsi\2k12R2\amd64\vioscsi.inf
"Red Hat VirtIO SCSI pass-through controller"
PCI\VEN_1AF4&DEV_1004&SUBSYS_00081AF4&REV_00
PCI\VEN_1AF4&DEV_1048&SUBSYS_11001AF4&REV_01

\viostor\2k12R2\amd64\viostor.inf
"Red Hat VirtIO SCSI controller"
PCI\VEN_1AF4&DEV_1001&SUBSYS_00021AF4&REV_00
PCI\VEN_1AF4&DEV_1042&SUBSYS_11001AF4&REV_01

When I use "VirtIO SCSI controller" in virt-manager,
and when I install Windows Server 2012 R2 -
I can use only viostor driver and can't use vioscsi driver,
Windows Server 2012 R2 can't load vioscsi driver (?)
from virtio-win.iso and did not see virtual hard disks
with vioscsi driver. Only viostor driver work normally.

How I can use "Red Hat VirtIO SCSI pass-through controller"
for Windows Server 2012 R2 virtual machine, what I need
to configure in xml-config?

current /etc/libvirt/qemu/windows.xml config:

   <controller type='scsi' index='0' model='virtio-scsi'>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
    </controller>

    <disk type='file' device='disk'>
      <driver name='qemu' type='raw' cache='none' io='native' discard='unmap'/>
      <source file='/volume/kvm-windows-system'/>
      <target dev='vda' bus='virtio'/>
      <boot order='1'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/>
    </disk>

Additional info:
================

virtio-win.iso version: virtio-win-0.1.126.iso
from https://fedoraproject.org/wiki/Windows_Virtio_Drivers

Maybe you can try the lastest virtio-win-0.1.133.iso :
https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/latest-virtio/virtio-win.iso

Or try to reinstall the latest spice guest tools 0.132 :
https://www.spice-space.org/download/binaries/spice-guest-tools/spice-guest-tools-latest.exe
 

OS: CentOS Linux release 7.3.1611 (Core)

QEMU: qemu-kvm-1.5.3-126.el7_3.5.x86_64

Why don't you upgrade qemu-kvm to qemu-kvm-ev ?
