Comment 30 for bug 586175

In qemu-kvm-0.12.5-r1 Windows XP/2003 is booting fine on IDE, but it hangs directly after the first reboot of the Windows setup if you try to install it on a viostor drive. Windows Vista and higher never had any problems in any version of qemu-kvm with any drive (IDE and viostor)...

I'm using the binaries of viostor-1.11.1, which I got from this site: http://www.linux-kvm.com/content/latest-windows-virtio-drivers
