Hello!!
I'd like to refer to this post: "RE: [Xen-devel] Re: How to intercept
interrupts from guest domains"
made by "Mads Bergdal" on 21 Sep 2006 in this list.
Mads try to intercept hypercalls made by a guest domain, from hypervisor.
I made this, modifying xen source (entry.S) and print on dmesg the
number of hypercall.
My question is: if in a guest domain an intruder install a rootkit
(for example an IDT hooking), my hypercall interception on Dom0 can
estabilished that there was a violation to that guest?? Is any rootkit
installed on guest detectable by my hypercall interception (for
example an rootkit that make a specific sequence of hypercalls)?
I hope that it isn't so complicated and I thanks you in advance for
comprehension.
Regards,
Elena
