[Qemu-devel] virtio with Windows 8.

[Yaodong Yang]

Hi all,

1. I create a raw image named as win8.img, using the following command:
/usr/local/kvm/bin/qemu-img create -f raw win8.img 20G

2. I try to install win8 with the following command, but I failed several times.

sudo /usr/local/kvm/bin/qemu-system-x86_64 -enable-kvm -drive file=./win8.img,if=virtio,cache=none -cdrom ./win8.iso -boot d -m 2048.

3. I try the same command but with if=ide, it works. 

Could someone tell me the reason for this failure? 

I appreciate it very much!

The Windows installer will not detect virtio-blk disks since Windows
does not come with virtio drivers by default.

You must provide the virtio-win drivers ISO during the installation:

https://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/bin/

Watch for the screen where Windows prompts you for a driver disk and put
in the virtio-win ISO.
