Hi,

I was just going through the (svm.c) svm_vmexit_handler() in the SVM
part of Xen, and saw that:

case VMEXIT_TASK_SWITCH:
        __hvm_bug(regs);
        break;

task switches are not intercepted and handled. I was wondering if it
is not so, then how do you manage consistency of the VM if the Guest
does a task switch (which could alter the value of CR3)? Am I missing
something here?

Thanks,
Vivek
