If qemu_opts_absorb_qdict() fails and we carry on and call update_flags_from_options() then that can result on a failed assertion: $ qemu-io -c 'reopen -o read-only=foo' hd.qcow2 block.c:1101: update_flags_from_options: Assertion `qemu_opt_find(opts, BDRV_OPT_CACHE_DIRECT)' failed. Aborted This only happens in bdrv_reopen_queue_child(). Although this function doesn't return errors, we can simply keep the wrong options in the reopen queue and later bdrv_reopen_prepare() will fail.
