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!
