Rusty, Jens, I need your opinion on the following patch. It seems to work, but I would like to get some feedback if this patch is the right approach: --- Currently virtio_blk assumes a 512 byte hard sector size. This can cause trouble / performance issues if the backing has a different block size (like a file on an ext3 file system formatted with 4k block size or a dasd device). Lets add a
