29	*
30	* The CPU Monitor / Manager keeps track of all the CPU registers.
31	* This is the ARMv8 variant which is doing much less than its x86/AMD6464
32	* counterpart due to the fact that we currently only support the NEM backends
33	* for running ARM guests. It might become complex iff we decide to implement our
34	* own hypervisor.
