I downloaded the floppy disk image (1.44M) from the Qemu Testing page here: http://wiki.qemu.org/Testing Then I ran: qemu-kvm -fda odin1440.img Just press enter on the default option, then at the C:\> prompt type "help", e.g. C:\>help <-enter-> This always results in: KVM internal error.

Given that this image is an actual example on the Qemu wiki, I would expect it to work. Albert
