In "Red Hat Enterprise Linux 6. Virtualization Host Configuration and Guest Installation Guide" in chapter 10.1 "Installing the KVM Windows para-virtualized drivers" it says:
The virtio-win package contains the para-virtualized block and network drivers for all supported Windows guest virtual machines. The virtio-win package can be found here in RHN
Alas, RHN is a premium feature of Red Hat Enterprise Linux. Are virtio drivers available on CentOS?
I needed to find the virtio drivers for Windows already unpacked. It turns out that Red Hat builds exactly such an ISO image for the Fedora Project (and for other KVM users), including signed virtio drivers.
I downloaded a copy of this ISO image and mounted it to the virtual machine. Then I clicked Load Drivers and navigated to the \win7\amd64 folder on the image to select the viostor driver.
At this point it found candidate drivers and I just clicked Add Drivers. I did not find it necessary to select anything in the list.
Finally it loaded the drivers within Startup Repair and I was able to see the virtual hard drive. One problem solved.
my kvm os is ubuntu 18.04, and I use
sudo fsck -y /dev/sda
sudo reboot
then all works good!
Best Answer
Yes, you can download the drivers from the upstream KVM project.
If you want an installable
virtio-winRPM package, similar to that provided by RHEL, then you can use the virtio-win yum repository provided by the Fedora Project.
