hello! i am a junior in XEN. so some questions may be very junior too, please give me more patience. I want to encrypt the data that will be written into the the disk, and the operation will happen in the Domain U''s front-end driver. and i notice that the write operation happens when the static int blkif_queue_request(struct request *req) functions in blkfront.c File is called and the data is put into the struct request *req I want to encrypt these data, and i want to if the data is in virtual address of the guest Domain U or virtual address of the the domain 0. If I want to encrypt the data ,should I do operation on these virtual address directely or do it after doing some translation. and do want translation. please help! Thanks very much! 2009-05-02 tianjiangbo16898 _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
