[Qemu-devel] hooking interrupt

[Antonio Ricci]

Hi all,
I'm new on this list.


I need to to intercept system calls running in the virtual machine from 
the host system. To do it I think that it could be useful to check when 
 the interrupt 0x80 is called and evaluate the value of the registers. 
Is it a correct way to proceed?

In the case of Argos I want to do this operations modifying the file 
target-i386/translate.c in order to check the registers value. Do you 
know if this is a correct way?

Someone suggested me to read the document explaining how to port qemu to 
new CPU, but I can't understand how to do hooking.

Thank in advance for your help
