--- Comment #21 from Jatin Kumar ---
The way I would approach this problem is to first check if there is a VM_EXIT
while executing this instruction. You should be able to find that in
vmx_vcpu_run() function (I guess in KVM code). Put a printk there and print the
instruction as well which caused VM_EXIT.
Futher you should try to investigate if the control flow is trying to emulate
this instruction and then your printk's should be triggered.
CAUTION: I haven't spent much time digging KVM code, but I am confident about
the VM_EXIT part. Still after putting in some effort, you may want to wait for
Paolo's reply :)
