Thanks, applied to the block branch. By the way, I tried converting a raw image to streamOptimised and got this: qemu-img: Could not write to allocated cluster for streamOptimized qemu-img: error while writing sector 63: Input/output error The problem seems to be that qemu-img tries to be clever and doesn't write out sparse parts, which breaks up the first cluster into multiple write requests. Adding -S 64 makes it work. Should we change something to get a working default? Kevin
