For windows, i use IDE HDD, therefore i set the drive prefix as “hd”, target as “hda” and the format is RAW. Hope this will help you ---

Vanilla windows with standard KVM/qemu will only see IDE disks. To use disk hotplugging you shoud use virtio. The drivers can be downloaded here: [http://www.linux-kvm.org/page/WindowsGuestDrivers/Download\_Drivers](http://www.linux-kvm.org/page/WindowsGuestDrivers/Download_Drivers)
