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>
