Xen users - Nov 2012 - What is the scenario of page copying from other domain?

Hi everyone,

I''m working on my master thesis about Xen. In order to add practical
value, I have to find the applicaiton scenario of the operation of copying page
from other domain (struct gnttab_copy, HYPERVISOR_grant_table_op).

Is there some systems/subsystems/drivers/... use page copying other than page
mapping or page transfer?

Thanks for your help!

Did you try using grep(1) in a kernel source tree for uses of this
operation?

Hi Ian,


Do you mean the Linux kernel when you refered "kernel"?


Thanks for your help for replying so fast. And thanks for your help for my
previous questions.

Please don''t top post, it breaks the flow of the conversation.

Well, any kernel which supports running as Xen dom0 or domU would be a
good starting point, and Linux seems like a reasonable candidate.

You might like to consider some of the points raised in
