[Xen-users] What is the scenario of page copying from other domain?

[summerxyt <summerxyt@xxxxxxxxx>]

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!
