libvirt users - Mar 2020 - Virtio-disk with driver from Microsoft from 2006 ?

Hi,

i wanted to benchmark a windows guest, compare standard driver and virtio
driver.
I installed the domain first with an IDE disk.
I followed
https://pve.proxmox.com/wiki/Paravirtualized_Block_Drivers_for_Windows to
install the virtIO driver.
In the device manager my VirtIO disk is recognized as a VirtIO SCSI disk from
RedHat which seems ok for me.
But the driver is, following the device manager, a driver from Microsft from
21/06/2006, version 10.0.18362.1.
That's strange in my eyes. This driver is outdated and not from RedHat or
Fedora, what i expected.
Also updating the driver and pointing to the CD, even the respective folder,
didn't work.
It says the driver is the most recent.
I used the virtIO-ISO 0.1.173, Windows 10 64bit Edition 1903.

Hi,

i found it out by myself. Important is the driver for the SCSI-Controller, not
for the disk itself.
The one for the controller is from Red Hat and its date is 12/08/2019.
