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>
