In general this seems to work for scsi disks or image files that contain a scsi bootmap. There are several things that we should fix or extend, though: - disabled wait - make cio better - pass a device id - loadparm - dasd bootmap (which is not architectured, but pretty similar to the scsi one) Can you provide a qemu tree so that we can help to fix/extend this? I think this should go into 1.5, lets see how much we can improve this before the hard freeze Christian
