He's determining the layout at runtime. It should even work with kvm's vmx implementation.
It's vulnerable to two issues: - fields that are cached in the processor and not flushed to memory (perhaps just make sure to VMXOFF before dumping memory) - fields that are encoded differently in memory than VMREAD/VMWRITE
