You are right at this point.

I'm not sure about this, 
But, if vcpus are not completely stopped before calling 
vmx_relinquish_vcpu_resources,
That's a big issue; vcpus may access some memories which have been freed and 
may be
used by other guys.
Keir,
When free_vcpu_struct() is called, is it guaranteed that this vcpu is stopped 
completely?
Thanks,
Anthony
