Should we make some effort to clear the flag once migration is done (i.e. via bdrv_reopen())? Also, should we set it everywhere where BDRV_O_INACTIVE is set (e.g. in postcopy migration, too)? Is it possible for these images to be opened R/W? If so, we have to make sure the source has also opened the image in shared mode, otherwise opening it will fail despite of BDRV_O_SHARE_RW. Max
