My idea is replace all bdrv_pread(), bdrv_pwrite_sync(), bdrv_pwrite() in block/vpc.c to bdrv_pread_split(), bdrv_pwrite_sync_split(), bdrv_pwrite_split() corresponding. bdrv_pread_split(), bdrv_pwrite_sync_split(), bdrv_pwrite_split() should deal with data splitted at different files via bdrv_pread(), bdrv_pwrite_sync(), bdrv_pwrite(), give an interface of sequential byte accessed. Is it suitable to solve this issue?? Thanks a lot Mitnick
