Anatomy of a trap
Hello,
I am a newbie at xen - I am trying to trace the complete execution of a
trap.
Specifically, I am trying to find out where the control transfer happens
between a domU to dom0 when a trap occurs, and where the control switches
back to domU after the trap is handled.
I was wondering if there is some documentation on this or someone may be
able to help me out.
Thanks,
Girish
