I tested it just yesterday (with kvm-83), and "qemu-img convert" does not correctly unpack my VHD image (from Microsoft Virtual PC) to raw, compared with the unpacked version from MSVPC's own conversion tool. There's some patches which greatly improve the VHD support; I'm not sure if they're in kvm-83. -- Jamie -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
