This does not work. qemu_opt_get_bool() takes a bool default argument and returns a bool. (bool)-1 == true. But (int)true == 1 and you cannot expect it to ever equal -1. Try this: if (qemu_opt_get(opts, "hostcache") && !qemu_opt_get_bool(opts, "hostcache", false)) { bdrv_flags |= BDRV_O_NOCACHE; } Stefan
