I'm not even sure this S_ISBLK/S_ISCHR test is necessary. > else if (lseek(fd, 0, SEEK_END) < total_size * BDRV_SECTOR_SIZE) > ret = -ENOSPC; > > qemu_close(fd); > return ret; > } > > > 2)or add a fallback in qemu-img, if bdrv_create doesn't exist, use bdrv_open > to see if the backend device is pre-existing ? Or even add it in block.c, so that it also applies to live snapshots etc. Paolo
