I'm running Windows 10 as guest via KVM / qemu. Unfortunately, Windows doesn't recognize the fedora virtio drivers I want to install for better HDD perfomance. The driver itself does show up, but installing it fails:

Qemu screenshot - "No new device drivers found"

I tried several driver versions, namely 0.1.102, 0.1.110 and 0.1.112, all for amd64.

Commandline options:

sudo qemu-system-x86_64 \ -device virtio-scsi-pci \ -drive if=none,id=hd,file=win.img,format=raw -device scsi-hd,drive=hd \ --enable-kvm \ -cdrom Win10_1511_German_x64.iso \ -m 4048 \ -drive file=$HOME/VirtualMachines/virtio-win-0.1.112.iso,id=driveriso,if=none,format=raw \ -device ide-cd,bus=ide.1,drive=driveriso \ -cpu host,kvm=off

What could cause Win 10 to reject those drivers? Are there better alternatives for fast HDD access from the Guest OS?

Host OS:

  • CPU: i7-6700k
  • OS: Ubuntu 15.10
  • uname -r: 4.3.4-040304-generic
  • uname -m: x86_64
  • qemu-system-x86_64 --version: QEMU emulator version 2.3.0 (Debian 1:2.3+dfsg-5ubuntu9.2)

  • I recommend strongly that you use virt-manager or virt-install with libvirtd to create VMs. Doing it manually can only result in trouble. Commented Mar 2, 2018 at 21:40

I had the similar problem when I tried to install Windows guest for KVM/qemu (on Ubuntu 14.04) using Packer.

I used stable virtio drivers from Fedora but the installation failed with the same error mesage. Then I found a workaround: when I changed storage type to IDE it worked.

After that I found and tried latest (not stable) drivers on Fedora website and the installation was successful.

I had a similar problem and i ended using ide-hd to install the driver once installed I changed it back to scsi-hd and it works fine :D

not sure why you have --enable-kvm and then you have -cpu host,kvm=off this is contracting and I believe qemu will use the last options passed.

sudo qemu-system-x86_64 \ -device virtio-scsi-pci,id=scsidev \ -drive if=none,id=hd,file=win.img,format=raw -device ide-hd,drive=hd \ --enable-kvm \ -cdrom Win10_1511_German_x64.iso \ -m 4048 \ -drive file=$HOME/VirtualMachines/virtio-win-0.1.112.iso,id=driveriso,if=none,format=raw \ -device ide-cd,bus=ide.1,drive=driveriso \ -cpu host,kvm=off
