My name is Thu, and I am currently working on virtualization security using Xen.
I am interested in intercepting hypercalls from DomU, and would like to know if I can do that using the hypercall_page kernel symbol. In other words, I would like to know if I can use it in the same way system call interception is done using the system_call_table.
I'd be happy if you guys can provide me with some tips on how I can intercept hypercalls in Xen.
Thanks a lot for your help and I look forward to hearing from you.
